During the Cold War phase, India was on the opposite side of the divide from the US as it had close relationship with Soviet. India’s decision to pursue a policy of NAM in 1945 was not liked by the US as it sided with Pakistan.
After the collapse of Soviet Union, India decided to liberalise its economy and integrate it with global economy. Hence, the US also found India an attractive economic partner due to technological dimension, and the role of Indian-American diaspora.
India-US relationship have never looked so brighter as it today. Both the countries are coming close to each other and both began to gain by coming closer.
Within India, the debate seems to be around three possible views. .

1. India should maintain its aloofness from the USA and forms upon increasing its other comprehensive national power.

Bangladesh has been the part of Pakistan itself. Both of these countries bear some similarities and differences as follows:
Commonalities :

1. Both Bangladesh and Pakistan were under a military rule.
2. At both the places, the struggle for democracy took place in their own way.
3. Pakistan’s administration began under the command of General Ayub Khan and gave up due to dissatisfaction among people giving way to Yahya’s military rule and continued with the army rule though elections were held by military rulers to give a democratic shape to their own rule.
4. In the same way, Bangladesh drafted its own constitution to begin with democracy. Sheikh Mujibur Rahman formed Presidential setup by abolishing all the parties except Awami Legue. But after his assassination the new military ruler Zia-ur-Rahman formed his own party and won elections in 1979. Later on he was also assassinated and another military leader Lt. Gen. H.M. Ershad took over.

Differences :

1. In Pakistan, military, clergy and land-owning aristocrats dominated socially to overthrow elected government whereas in Bangladesh the leaders and their party members dominated for the same.
2. Pro-military groups have become more powerful due to conflict with India in Pakistan whereas in Bangladesh, pro-military groups are powerful due to friendship and encouragement of India.

Answer 24.
The following factors are responsible for Pakistan’s failure in building a stable democracy :

1. The lack of genuine international support for a democratic rule in Pakistan has encouraged to military to continue its dominance. The US and other countries have also supported military rule due to fulfilling their own interests.
2. Pakistan’s conflict with India has made paramilitary groups more powerful which have often said that political parties and democracy in Pakistan are flawed, that Pakistan’s security would be harmed by selfish minded parties and chaotic democracy, hence army stay in power is justified.
3. The social dominance of military, clergy, and owning aristocracy has led to frequent overthrow of elected governments and the establishing of military governments.
4. Global Islamic terrorism and their apprehension that Pakistan’s nuclear arsenal might
   fall into hands of these terrorist groups, the military regime in Pakistan was seen as the protector of western interests in West Asia and South Asia.

The two pro-democracy factors present in Pakistan that can pave the way for establishing a lasting democratic set up over there are:

• Pakistan bears a courageous and entirely free press.
• Pakistan enjoys strong human rights movement.

OR

The process of partition had been started in 1940 when Muslim League under the leadership of Muhammad Ali Jinnah propounded Two-Nation Theory. This process involved various problems:

1. Areas were supposed to be distributed on the basis of religions majority i.e. Muslim majority areas built Pakistani territory and rest stayed with India. It created communal riots in country.
2. No single belt of Muslim majority was the part of British India. They were concentrated in East and West. Hence, it was decided that Pakistan will comprise two territories namely East and West Pakistan separated by long expansion of India territory,
3. All Muslim majority areas did not want to be merged with Pakistan i.e. it was opposed in NWFP. But ultimately NWFP was made to merge with Pakistan.
4. Another problem belonged to minorities on both sides of border i.e. lakhs of Hindus and Muslims and Sikhs from both the sides were left with no option except to leave f their homes.

3. Despite being taken place of free and fair elections, Congress won elections in the
   same manner again and again.
4. The Congress Party consisted of various factions inside itself, based on ideological considerations who never taught together or went out of Congress.
5. Hence, on the basis of above mentioned criterion, it can be concluded that Congress strengthened ideals of democracy and held unity and integrity of the country.

Circumstances that favoured Indira Gandhi to become Prime Minister after the death of Lai Bahadur Shastri are as follows:

1. On 10 January 1966, Shastri’s Prime Ministership came to an abrupt end when he died suddenly in Taskhent. Now, the Congress had to face the challenge of political succession.
2. The senior party leaders decided to support Indira Gandhi, but the decision was not unanimous. There was intense contest between Morarji Desai and Indira Gandhi. The contest jvas resolved through a secret ballot among the MPs of the Congress. Indira Gandhi got the support of more than two-thirds of the Congress party’s MPs.

Achievements of Indira Gandhi that made her popular as a Prime Minister are:

1. Indira Gandhi adopted her strategy boldly and diplomatically. When the Congress had lost in 1967 elections, she converted a simple power struggle into an ideological struggle.
2. Indira Gandhi did not revive old Congress Party but she re-invented the party by forming an entirely different popular party to accommodate some social groups, the poor, the women, the dalits, adivasis and the minorities. Thus, she restored the Congress system by changing the nat are of Congress system itself.
3. Indira Gandhi focussed on the growth of the public sector, imposition of ceiling on rural land holdings and urban poverty, removal of disparities in income and opportunity, and abolition of princely privileges. Her slogan ‘Garibi Hatao’ and the programmes that followed it were part of her political strategy of building an Independent nationwide political support base. As a result, she won 352 seats with about 44 per cent of the popular votes on its own in the Lok Sabha elections of 1971.
4. After the 1971 Lok Sabha election, a major political and military crises broke out in East Pakistan (present Bangladesh). The 1971 elections were followed by the crisis in East Pakistan and the Indo-Pak war leading to the formation of Bangladesh.

All these events added to the popularity of Indira Gandhi. Even the opposition party leaders admired her statesmanship.

Question 17.
Read the following passage carefully and answer the questions:
The global economy relied on oil for much of the 20th century as a portable and indispensable fuel. The immense wealth associated with oil generates political struggles to control it, and the history of petroleum is also the history of war and struggle. Nowhere is this more obviously the case than in West Asia and Central Asia. West Asia, specifically the Gulf region, accounts for about 30 per cent of global oil production. But it has about 64 per cent of the planet’s known reserves, and is therefore the only region able to satisfy any substantial rise in oil demand. Saudi Arabia has a quarter of the world’s total reserves and is the single largest producer. Iraq’s known reserves are second’only to Saudi Arabia’s. And, since substantial portions of Iraqi territory are yet to be fully explored, there is a fair chance that actual reserves might be far larger. The United States, Europe, Japan, and increasingly India and China, which consume this petroleum, are located at a considerable distance from the region.
(i) Which region has much potential for oil production?
(ii) Which area is supposed to have far larger reserves than actually it has?
(iii) Why is the history of petroleum called the history of war and struggle?

Question 18.
Read the following passage carefully and answer the questions:
At the most simple level, globalisation results in an erosion of state capacity, that is, the ability of government to do what they do. All over the world, the old ‘welfare state’ is now giving way to a more minimalist state that performs certain core functions such as the maintenance of law and order and the security of its citizens. However, it ‘ withdraws from many of its earlier welfare functions directed at economic and social well-being. In place of the welfare state, it is the market that becomes the prime determinant of economic and social priorities. The entry and the increased role of multinational companies all over the world leads to a reduction in the capacity of governments to take decisions on their own. At the same time, globalisation does not always reduce state capacity. The primacy of the state continues to be the unchallenged basis of political community. The old jealousies and rivalries between countries have not ceased to matter in world politics. The state continues to discharge its essential functions (law and order, national security) and consciously withdraws from certain domains from which it wishes to. States continue to be important. Indeed, in some respects state capacity has received a boost as a consequence of globalisation, with enhanced technologies available at the disposal of the state to collect information about its citizens. With this information, the state is better able to rule, not less able. Thus, states become more powerful than they were earlier as an outcome of the new technology.
(i) How does globalisation effect on state capacity?
(ii) How have multinational companies effected the states?
(iii) How does the old welfare state react to globalisation?

Question 19.
Study the picture given below and answer the questions that follow:

(i) Identify the person in the centre of the cartoon and mention the challenge surrounding him.
(ii) What does the picture actually refer?
(iii) How did India avoid all these conflicts?

Question 20.
Read the passage given below carefully and answer the following questions:
This coalition-like character of the Congress gave it an unusual strength. Firstly, a coalition accommodates all those who join it. Therefore, it has to avoid any extreme position and strike a balance on almost all issues. Compromise and inclusiveness are the hallmarks of a coalition. This strategy put the opposition in a difficulty. Anything that the opposition wanted to say, would also find a place in the programme and ideology of the Congress. Secondly, in a party that has the nature of a coalition, there is a greater tolerance of internal differences and ambitions of various groups and leaders are accommodated. The Congress did both these things during the freedom struggle and continued doing this even after Independence. That is why, even if a group was not happy with the position of the party or with its share of power, it would remain inside the party and fight the other groups rather than leaving the party and becoming an ‘opposition’.
(i) What do you mean by a faction?
(ii) How did coalition-like character affect the nature of the Congress Party?
(iii) How did the Congress avoided to increase number of‘opposition’?

Question 21.
On a political outline map of India, locate and label the following and symbolise them as indicated:

The Communist Party of India was founded in 1920. In the early 1920s, Communist groups emerged in different parts of India taking inspiration from the Bolshevik revolution in Russia and advocating socialism as the solution to problems affecting the country. From 1935, they worked mainly from within the fold of the Indian National Congress. A parting of ways took place in December 1941, when the Communists decided to support the British in their war against Nazi Germany. At the time of Independence, other non-Congress parties like the CPI had a dedicated cadre. Soon after Independence, the Communist Party thought the transfer of power in 1947 was a not true independence and encouraged violent uprisings in Telangana, but they failed to generate popular support for their position and were crushed by the armed forces.

In 1951, the Communist Party abandoned the path of violent revolution and decided to participate in the approaching general elections. In the first general elections, CPI won 16 seats and emerged as the largest opposition party. The party’s support was more concentrated in Bihar, West bengal, Andhra Pradesh West Bengal, Bihar and Kerala, The party leaders included A.K. Gopalan, S.A. Dange, E.M.S. Namboodiripad, P.C. Joshi, Ajay Ghosh and P. Sundarraya.

Answer 25.
At the time of the Second Five Year Plan, some controversial issues rose in reference to relevancy of agriculture over industry.

• The Second Five Year Plan emphasised on industry in place of agriculture or rural India.
• J.C. Kumarappa, a Gandhian economist proposed an alternative blueprint to emphasise on rural industrialisation.
• Bharatiya Lok Dal leader, Chaudhary Charan Singh also commented that the planning leading to creation of prosperity in urban and industrial sections at the cost of rural welfare.

Others debated that without an increase in industrial sector poverty could not be alleviated:

• India planning did not have an agrarian strategy to boost the production of food grains.
• It also proposed programmes of community development and spent large sums on irrigation project and failure was not that of policy but of its non-implementation because of the politics of land owning classes.
• Besides, they also argued that even if the government had spent more money on agriculture, it would not have solved the massive problem of rural poverty.

OR

No, this was not the failure of foreign policy but this was a result of international situation:
(i) The Chinese Invasion, 1962 :

• Serious conflict arose when China annexed Tibet in 1950 and removed a historical buffer between two nation, and India did not oppose this openly.
• India grew uneasy, when China began to suppress Tibetan Culture.
• Another border dispute arose when China claimed Aksai Chin area and NEFA (much of the state in Arunachal Pradesh) within the Indian territory.
• Despite long-term correspondence and discussions, these issues have not been resolved even by top leaders of country.
• Hence, India had to indulge in the conflict.

(ii) War with Pakistan :

• A serious armed conflict between two countries began in 1965 with the initiative of Pakistan over Kashmir partition.
• In 1966, the hostilities came to an end with the UN intervention and Tashkent Agreement signed between Indian Prime Minister Lai Bahadur Shastri and Pakistan’s General Ayub Khan.
• The 1965 War added to India’s already difficult economic situation.

(iii) Bangladesh War of 1971 :

• In 1970, Pakistan faced its biggest crisis in the way for a split verdict i.e. Zulfikar Ali Bhutto’s Party emerged as winner in West Pakistan while Awami league led by Sheikh Mujibur Rehman swept through East Pakistan.
• The Bengali population of East Pakistan had voted to protest against discriminatory attitude of West Pakistan, which was not acceptable to West Pakistan rulers.
• In 1971, Pakistani army arrested Sheikh Mujib and unleashed a region of terror on Eas(t Pakistan. This started people’s struggle to liberate Bangladesh from Pakistan.
• India had to bear 80 lakh refugees who fled from East Pakistan to take shelter. Hence, India had to extend moral and material support to the freedom struggle in Bangladesh.
• A full scale war between India and Pakistan in December 1971 broke out, when Pakistan attacked on Punjab and Rajasthan to be.retaliated an attack from India.
• Within ten (Jays the Indian army surrounded Dhaka and Pakistan had to surrender with Bangladesh as a free country, India declared a unilateral ceasefire and Shimla Agreement was signed between India and Pakistan in 1972.
• Most people in India saw this moment as a glory of India and a clear sign of India’s growing military powers.

4. In April 1976, finally it was proved that the government could take away citizen’s right to life and liberty by overruling of High Courts under Supreme Court and accept government’s plea.

(b) Impact on Relationship between the Executive and Judiciary :

1. The Parliament brought in many new changes in the Constitution which made an amendment declaring that elections of the Prime Minister, the President and the Vice-President could not be challenged in the court.
2. The 42nd amendment was also passed to bring a series of changes in the Constitution like duration of legislatures, elections can be postponed by one year during an emergency.

Answer 27.

1. Narmada Bachao Aandolan (NBA) linked its opposition to Sardar Sarovar Project with larger issues concerning the nature of ongoing developmental projects, efficacy of model of development that the country followed and what constituted public interest in a democracy.
2. It demanded that there should be a cost benefit analysis of the major developmental projects due to construction of dam submerged around 245 villages to require two half a lakh population to be relocated.
3. The movement demanded proper rehabilitation of all those to be affected from the construction of these projects.
4. This movement also questioned the nature of decision making process to be in forming of mega scale development projects.
5. Movement also insisted that local communities must have a say in such decision making alongwith an effective control over natural resources.
6. Hence, NBA achieved a comprehensive National Rehabilitation Policy formed by government in 2003.

Democratic strategies used by it :

• Mobilisation of support at inter-national level
• Appeals to judiciary
• Public rallies
• Forms of Satyagraha

OR

Yes, we agree with the statement because India adopted a democratic approach on these regional aspirations in place of considering them as anti-national:

1. India’s democratic politics allows people and groups to address the people on the basis of their regional identity, aspiration, and specific regional problems.
2. India’s democratic politics focus on regional issues and problems to receive adequate attention and accommodation in the policy making process, i.e. regional aspirations of Assam, Punjab and North-East, Kashmir, etc.
3. Its examples are in eighties, military erupted in Punjab, problems persisted in the North-East, students agitated in Assam and Kashmir valley was on the boil.
4. The Government of India settled down some negotiations with these regional aspirations to reduce tensions in many regions.
5. Mizoram is an example of political settlement to resolve the problem of separation effectively.
   It can be concluded that regional aspirations do not encourage separation but these respect diversity to retain unity in the nation.

Principle :
When a current-carrying coil is placed in a magnetic field, it experiences a torque. From the measurement of the deflection of the coil, the strength of the current can be computed. A high resistance is connected in series with the galvanometer to convert it into voltmeter. The value of the resistance is given by

Here,
V = Potential difference across the terminals of the voltmeter
I_g  = Current through the galvanometer
G = Resistance of the galvanometer
When the resistance R₁, is connected in series with the galvanometer,
V = I (G + R₁)
When the resistance R₁ is connected in series with the galvanometer,

Let R₃ be the resistance required for conversion into voltmeter of range 2V

Answer 13.
A photo diode is used to observe the change in current with change in the light intensity under reverse bias condition. In fabrication of photo diode, material chosen should have band gap -1.5 eV or lower so that solar conversion efficiency is better. This is the reason to choose Si or GaAs material. Working: It is a p-n junction fabricated with a transparent window to allow light photons to fall on it. These photons generate electron hole pairs upon absorption. If the junction is reverse biased using an electrical circuit, these electron hole pair move in opposite directions so as to produce current in the circuit. This current is very small and is detected by the micro ammeter placed in the circuit.

A photo diode is preferably operated in reverse bias condition. Consider an «-type semiconductor. Its majority carrier (electron) density is much larger than the minority hole density. When illuminated with light, both types of carriers increase equally in number

That is, the fractional increase in majority carriers is much less than the fractional increase in minority carriers. Consequently, the fractional change due to the photo-effects on the minority carriers dominated reverse bias current is more easily measurable than the fractional change in the majority carrier dominated forward bias current. Hence, photo diodes are preferably used in the reverse bias condition for measuring light intensity.

Answer 14.
(a) Einstein’s photoelectric equations is given by

Where
K_max ⁼ Maximum kinetic energy of the photoelectron
^vmax ⁼ Maximum velocity of the emitted photoelectron
m = Mass of the photoelectron
v = Frequency of the light radiation
Φ₀ = Work function h = Planck’s constant
If v_o is the threshold frequency, then the work function can be written as

The above equations explains the following results.

1. If v < v_o, then the maximum kinetic energy is negative, which is impossible. Hence, photoelectric emission does not take place for the incident radiation below the threshold frequency. Thus, the photoelectric emission can take place only if
   v > v_o.
2. The maximum kinetic energy of emitted photo electrons is directly proportional to the frequency of the incident radiation. This means that maximum kinetic energy of photo electron depends only on the frequency of incident light.

(b) According to the photoelectric equation,

Answer 15.
Let us consider a Wheatstone bridge arrangement as shown below :
Wheatstone bridge is a special bridge type circuit which consists of four resistances, a galvanometer and a battery. It is used to determine unknown resistance. In figure four resistance P, Q, R and S are connected in the form of four arms of a quadrilateral. Let the current given by battery in the balanced position be I. This current on reaching point A is divided into two parts I₁ and I₂. As there is no current in galvanometer in balanced state, therefore current in resistances P and Q is I₁ and in resistances R and S it is I₁.


This is condition of balanced Wheatstone bridge

Answer 16.
From this experiment, the following is observed :

1. Most of the alpha particles pass straight through the gold foil. It means that they do not suffer any collision with gold atoms.
2. About one alpha particle in every 8000 alpha particles deflects by more than 90°. As most of the alpha particles go undeflected and only a few get deflected, this shows that most of the space in an atom is empty and at the centre of the atom, there exists a nucleus. By the number of the alpha particles deflected, the information regarding size of the nucleus can be known.

If m is the average mass of a nucleon and R is the nuclear radius, then mass of nucleus = mA, where A is the mass number of the element. This shows that the nuclear density is independent of A.

Answer 17.

Answer 18.

1. When the number of turns in the inductor is reduced, its reactance X_L decreases. The current in the circuit increases and hence brightness of the bulb increases.
2. When an iron rod is inserted in the inductor, the self inductance increases. Consequently, the inductive reactance X_L = coL increases. This decreases the current in the circuit and the bulb glows dimmer.
3. With capacitor of reactance X_c = X_L, the impedance
   
   becomes minimum, the current in circuit becomes maximum. Hence the bulb glows with maximum brightness.

Answer 19.

When a message is received, it gets attenuated through the channel therefore, receiving antenna is to be followed by an amplifier and a detector. The signal frequency is usually changed to a lower frequency in an Intermediate Frequency (IF) stage. The detected signal may not be strong enough to be made use of and hence is required to be amplified. In order to obtain the original message signal m(t) of angular frequency a simple method is used which is shown in the form of a block diagram.

When the received modulated signal is passed through a rectifier, an envelope signal is produced. This envelope signal is the message signal. In order to retrieve the message, the signal is passed through an envelope detector.

Answer 23.

1. The device that is used to bring high voltage down to low voltage of an a.c. current is a transformer. It works on the principle of mutual induction of two windings or circuits. When current in one circuit changes, emf is induced in the neighbouring circuit.
2. The transformer cannot convert d.c. voltages because it works on the principle of mutual induction. When the current linked with the primary coil changes, the magnetic flux linked with the secondary coil also changes. This change in flux induces emf in the secondary coil. If we apply a direct current to the primary coil the current will remain constant. Thus, there is no mutual induction and hence no emf is induced.

OR

(a) (i) Conductor :
E₀ → external field
E_m → internal field created by the redistribution of electrons inside the metal.
When a conductor like a metal is subjected to external electric field, the electrons experience a force in the opposite direction collecting on the left hand side. A positive charge is therefore induced on the right hand side. This creates an opposite electric field (E_m) that balances out (E₀).

∴ The net electric field inside the conductor becomes zero.

(ii) Dielectric :
When external electric field is applied, dipoles are created (in case of non-polar dielectrics). The placement of dipoles is as shown in the given figure. An internal electric field is created which reduces the external electric field.  Polarization of dielectric (P) is defined as the dipole moment per unit volume of the polarized dielectric.

^p = X_es₀ E
X_e = susceptibility
E = Electric field

Answer 26.
(a) Amperes circuital law in electro magnetism is analogous to Gauss law in electrostatics. This law states that “The line integral of resultant magnetic field along a closed plane curve is equal to p₀ time the total current crossing the area bounded by the closed curve provided the electric field inside the loop remains constant. Thus ƒ B .dl = μ.₀I_enc, where p₀ is permeability of free space and I_enc is the net current enclosed by the loop.

A toroid is a hollow circular ring on which a large number of turns of a wire are closely wound. Consider an air-cored toroid (as shown here) with centre O.
Given,
r = Average radius of the toroid
I = Current through the solenoid .
n = Number of turns per unit length

To determine the magnetic field inside the toroid, we consider three amperian loops (loop 1, loop 2 and loop 3) as show in the figure below.

This is the expression for magnetic field inside air-cored toroid.
(b) Given that the current flows in the clockwise direction for an observer on the left side of the solenoid. This means that left face of the solenoid acts as south pole and right face acts as north pole. Inside a bar magnet the magnetic field lines are directed from south to north. Therefore, the magnetic field lines are directed from left to right in the solenoid. Magnetic moment of single current carrying loop is given by
m = IA
where
I = Current flowing through the loop;
A = Area of the loop So, Magnetic moment of the whole solenoid is given by
M = Nm = N(IA)

Effects of Exercise of Cardiovascular System

• The benefits of regular exercise include more than just having a well-toned body. Besides serving as a mood intensifier, physical activity has both long term and short term effects on the cardiovascular system. Good blood circulation throughout your body may provide long standing positive effects to your health.
• Before the person starts exercising, the body go through an anticipative response. During this response the body will release adrenaline consistently before the person sweat. Increases stroke volume: Stroke volume is the amount of blood pumped out of the heart during each contraction. Stroke volume is measured in milliliters per beat. With the onset of exercise, the stroke volume increases anywhere from 60 to 110 milliliters depending on the intensity.
• Lowers blood pressure: A healthy heart rate of an adult at rest is about 60-80 beats per minute. With regular exercise, a lower resting heart rate can be developed. Resting heart rate decreases because the heart develops to hold more amount of blood with exercise.
• Lowers blood pressure: Blood pressure repose with two measurements. The systolic number refers to the amount of pressure that helps to drive blood throughout the system. Blood circulation or flow improves with regular exercise and lowers the blood pressure readings.
• Improves blood flow: An additional short term effect of the circulatory system during exercise is how the blood is delivered throughout the body. When a person is at rest only 15 percent of the blood flowing through the body is drifted towards the skeletal muscles.
• Fewer varicose veins: Regular exercise not only boost leg strength, but also improves vien strength. Stronger veins will lower the risk of getting varicose veins.
• Other long term effects of regular exercise Increases the number of red-blood cells and
  capillaries. Diminishes stress-related hormones from circulating in the blood. Enhances the blood vessel lining which in turn helps to lower the risk of plaque buildup that may lead to coronary disease.
• Probably the first part of your body to benefit from regular exercise is your heart. To get the blood circulated to different parts of your body requires a healthy heart that is able enough to function efficiently. Regular exercise makes your heart stronger so that it won’t have to work as hard as the heart of the one who doesn’t exercise.

Answer 17.
Body largely depends upon the structure of joints, muscles, tendons and ligaments. Flexibility is crucial for performing routine work. It can even prevent injury, especially lower back pain. When joints are flexible, body can perform movements with greater amplitude and range without external help commonly called as active flexibility. But when external help is taken by the body for performing movements, it is called as passive flexibility. Therefore if joints are flexible then easy movements structuring and muscle contractions are possible as required in sports like gymnastics, yoga, swimming and athletics.

Answer 26.
Impacts of high altitude training are:

• At high altitudes the reduced air pressure, oxygen diffuses into red blood cells more slowly.
• To compensate the decreased oxygen, one of the body’s hormone erythropoietin (EPO), triggers the production of more red blood cells to aid in oxygen delivery to the muscles.
• Training at high altitudes results in the production of RBC’s.
• Then athletes head to a competition at lower elevations to take advantage of their changed physiology.
• Natural blood doping – Idea of taking advantage of the body’s physiological changes at high altitude.

Answer 13.

The Law of Inertia: A body at rest tends to remain at rest. A body in motion tends to continue in motion with consistent speed and in the same direction unless acted upon by an outside force. Example is the most anything in the real world—gravity, the surface of the playing field, a defensive player, or the braking action of an athlete’s body to stop.

The Law of Acceleration: The velocity of a body is changed only when acted upon by an additional force. The produced acceleration or deceleration is proportional to and in the same direction of the force. If a baseball player hits a ball with double the force, the rate at which the ball will accelerate (speed up) will be doubled. Football players can slow down, stop, or reverse the direction of other players depending upon how much force they can generate and in which direction.

The Law of Counterforce: The production of any force will create another force opposite and equal to the first force. A swimmer propels herself through the water because the water offers enough counterforce to oppose the action of her hands pushing, allowing her to move. An athlete can jump higher off a solid surface because it opposes his body with as much force as he is able to generate, in contrast to sand or other unstable surface.

Answer 14.
Nutrients are environmental substances used for energy, growth and bodily functions by organisms. Depending as the nutrient, these substances are needed is small amounts or larges amounts. Those that are needed in large amounts are called Macronutrients.

Micronutrients: as opposed to Macronutients. (protein, carbohydrates and fat), are comprised of vitamins and minerals which are required in small quantities to ensure normal metabolism, growth and physical well-being.
Minerals can be classified as macro minerals like calcium, potassium, sodium, magnesium, phosphorous and micro mineral (like iodine, iron, chromium, etc.)
Vitamins can be soluble like Vitamin A, D, E, etc.) or water soluble (like Vitamin B complex, B2, B3 etc.)

Answer 15.
Mal-posture means faulty carriage or incorrect alignment of different parts of body in respect to each other. It occurs due to the following reasons.

• Muscular weakness
• Malnourishment
• Faulty desks and seats
• Defective eye-sight or hearing
• Improper exercises
• Typical occupations
• Too rapid growth during adolescence
• Carrying weights
• Use of improper belonging
• Poor posture of teachers
• Heredity and environments

Answer 16.
Growth of the child: As children grow and learn, their ability to perform more activities with their body and understand actions improves. This can be affected by age and size. While most motor development skills have age-specific target ranges, the skills are also influenced by children being small or tall for their age, their weight, and their mental development.

Environment: The child’s environment has a large effect on their motor skill development. The more opportunities they have to develop both gross and fine motor skills, the faster their capacity increases. For instance, if a child is encouraged to play outside on park equipment or other areas where they can climb, run, and play, their gross motor skills will develop quickly. Additionally, fine motor skills increase when children are encouraged to play with their hands, hold and touch smaller items, feed themselves, and draw or color.

Genetics: Children are affected both by the genetics of their parents and their own genetics. If there are genetic weaknesses, they may have slower motor skill development than general guidelines suggest for their age range. For instance, if a child has weak muscle tone or health issues, they will likely develop at a slower pace than other healthy children of their age.

Muscle Tone: As mentioned previously, muscle tone can affect motor skills. The stronger a child is, the more ability they may have to move and control their body. Muscles are a fundamental factor in a child having the strength to move their body and control their actions. If muscle development is weak, their motor skill development will be slower.

Gender: Gender plays an important role in how children develop. Boys often have more advanced motor skills than girls because they are typically stronger and more aggressive physically. At the same time, girls often have more advanced eye and hand coordination. They may be more able to balance fine motor skills and gross motor skills, using both large movements and more detailed actions interchangeably.

Answer 18.
Types of Fracture:
(i) Close Fracture:

• Transverse Fracture: Broken at right angle to long axis of bone
• Oblique: Oblique direction to long axis, confined to one plane .A fracture in which the line of break runs obliquely to the axis of the bone.
• Spiral Fracture: Occur when one end of an extremity is fixed (e.g., a foot is planted on the floor) but the rest of the extremity remains in motion.
• Comminute Fracture: A fracture in which the bone has broken or fragmented into several pieces. It happens mostly due to crush.
• Impact Fracture: An impacted fracture is one whose ends are driven into each other.
• Green Sticks: fracture in a young, soft bone in which the bone bends and partially breaks

(ii) Open Fracture:

• Compound Fracture: An open fracture, also called a compound fracture, is an injury that occurs when there is a break in the skin around a broken bone. In order for an injury to be classified as a compound fracture, the outside air (and dirt and bacteria must be able to get to the fracture site without a barrier of skin or soft-tissue.

Answer 19.
Total number of teams =09
Upper half = n + 1/2 = 09+1/2 = 5

Answer 20.
Role of sports in personality development are as following:
(i) Development of cognitive abilities: through sports participation cognitive process of athletes to perceive, evaluate and regulate their behaviour, which is appropriate in given situation improves. It benefits the following cognitive functions of processing information from received stimulus:

• Influence Intelligence
• Develops attention span
• Improves concentration

(ii) Control on arousal and emotion: sports participation helps in psycho-physiological activation helps in avoidance of negative emotions state of feeling of nervousness, apprehension associated with arousal of the body.

• Reduce anxiety
• Regulate aggression

(iii) Promote Social Cohesion: Sports participation

• Team association increases
• Task association increases

(iv) Create Leadership abilities: Sports participation helps in development of behaviour process of influencing individuals and groups towards set objectives. Athletes are able to take initiative and guide others in performing some required task in an organized form to task attainment. It help in the following:

• Develop ownership
• Creates responsibility

(v) Self-Efficacy: Sports participation develops belief in athletes to perform task successfully. Sports participation supports individual belief in his or her competencies and abilities to succeed in particular task.

Answer 21.
Role of nutrition in sports performance can be divided in three phases, Pre-competition, During Competition, Post Competition.
(i) Pre-Competition:

• Carbohydrate loading before competition helps in storing of glycogen which helps in extra energy during competitions.
• Sufficient intake of fluid before competitions help in prevention of dehydration.

(ii) During Competition:

• Small amount of carbohydrates at regular interval helps in maintain blood sugar level and reduces fatique.
• Frequent intake of fluids are beneficial to stay hydrated during high intensity level activities.

(iii) Post Competition:

• Initial intake of carbohydrate after competitions help in restoring glycogen.
• To enhance muscle recovery, protein diet after few hours of competition is helpful.
• A balanced diet containing of macro and micro nutrients post competitions helps in faster recovery and reduced chances of injury.

Essential nutrients required for performance:
Fat: it is major source of fuel, various sports require different proportion of fat to muscles, although extra fat influences performance.

Carbohydrates: it is a major fuel for muscular contraction. It helps in decrease of fatigue. Low level of carbohydrates results in formation of lactic acid leading to early fatigue. Protein: It is required for growth of tissues. Protein is used as for repair of cells and tissues leading to faster growth and development of muscles. It does have significant effect on performance.

Minerals: are essential for energy balance, deficiency decreases performance and increases chances of injury.

Vitamins: Essential for balance growth by avoiding deficiency. Vitamins protect the body from preventing external bodies to create damage and produce disease in the body.

Answer 22.
Protection, Rest, Ice, Compression and Elevation, or P.R.I.C.E., adds the concept of “protection” to the traditional R.I.C.E. protocol formula. Protecting the injured area from further damage is crucial to the healing process.
P: Protection is meant to prevent further injury. For example, an injured leg or foot may be protected by limiting or avoiding weight-bearing through the use of crutches, a cane, or hiking poles. Partially immobilizing the injured area by using a sling, splint, or brace may also be a means of protection.

R: Rest is important to allow for healing. However, many sports medicine specialists use the term “relative rest” meaning rest that allows for healing, but is not so restrictive that recovery is compromised or slowed. A person should avoid activities that stress the injured area to the point of pain or that may slow or prevent healing.

I: Ice refers to the use of cold treatments, also known as cryotherapy, to treat acute injuries.Ice is recommended with the intent to minimize and reduce swelling as well as to decrease pain. The most common and most convenient is a simple plastic bag of crushed ice placed over a paper towel on the affected area. It is important to protect the skin and limit the cold exposure to 10 to 15 minutes.
Skin sensitivity or allergy to cold exposure can occur. Skin may become mottled, red and raised where the ice contacted the skin. If this is experienced, the ice treatments should be discontinued.

C: Compression is the use of a compression wrap, such as an elastic bandage, to apply an external force to the injured tissue. This compression minimizes swelling and provides mild support.
Elastic bandage should be applied directly to the skin by starting a few inches below the injury and wrapping in a figure eight or spiraling manner to a few inches above the injured area.
A medium amount of tension should be applied to provide ample, but not too constrictive
compression. The bandage should not cause numbness, tingling, or color change of the soft ‘ tissue.
E: Elevation is recommended to help reduce the pooling of fluid in the injured extremity or joint. Controlling swelling can help decrease pain and may limit the loss of range of motion, possibly speeding up recovery time.

Answer 23.
Effect of exercise on cardiovascular system:
(i) Exercise Effect:

• Increase in stroke volume: it is the amount of blood ejected per beat from the left r ventricle. During activity SV increases 2-3 times from the resting SV.
• Increase in Heart Rate: Heart Rate is the amount of contraction of left ventricles per minute. During exercise HR increases.
• Cardiac Output: Cardiac Output is the amount of blood pumped from the heart per minute. Cardiac Output is the product of HR and S V. A resting Cardiac Output is 5L/ Min which can increase to 20 – 40 L/min after an intense exercise.
• Increase in Blood Flow: More amount of blood is required by the tissue for immediate demand. At rest, 15-20% of blood is released to skeletal muscles, whereas during intense exercise 80-85% of blood is transported to skeletal muscles.
• Increase in Blood Pressure: During exercise the systolic blood pressure increases 50¬70 mm/hg. Diastolic blood pressure remains unchanged.

(ii) Long Tem Effects:

• Increase in size of heart: Muscles of the heart increase in size. The left ventricle adapts
  to the greatest extent. This phenomenon is also called as ‘Cardiac Hypertrophy’ which is not a disease. –
• Decrease Resting Heart Rate: Regular exercise decreases the resting heart rate. Resting Heart Rate of 72beat/min can reduce to 30-40 beat/min in highly conditioned athletes.
• Increase in Resting Stroke Volume: After continuous training of several years, resting stroke volume increases to 70-0 ml/beat from 50-70 ml/beat.

Answer 24.
The parabolic path followed by a projectile is called its trajectory.
Factors:

1. Initial velocity: Initial velocity is directly related to the distance covered in flight. The speed of release depends on initial vertical velocity and initial horizontal velocity. Having higher horizontal velocity will increase the distance covered.
2. Angle of projection: An object which is projectedat different angles but the same initial velocity covers different distances. When it is released at an angle of 45o, covers maximum distance.
3. Projection height: The higher the level of release, the longer distance covered in the flight. The horizontal component will be acting on the projectile for longer duration; hence projectile will be covering a longer distance.
4. Gravity: Gravitational force is exerted by earth on all the objects. It is constant for all the objects. It decreases at the places of high altitude.
5. Spin: it is amount and direction of spin directly affects the distance covered. The spin covered low pressure on the top, the object remains in air for longer period covering longer distance. If the spin creates high pressure on the top, the object remains in air for shorter period and covers shorter distance.
6. Air Resistance: When a projectile moves through the air, it is slowed down by air resistance. It decreases the horizontal velocity of the projectile

Answer 25.
AAPHER motor fitness test was formed in 1965 in United States. It included these items:

• Pull ups (boys)
• Flexed arm stand (girls)
• sit ups 600 yard run walk
• shuttle run
• 50 yard dash etc.

1. Pull ups – to measure arm and shoulder strength
   Procedure – the bar was adjusted according to the height of the subject. The student is advised to raise his body so that the chin reaches the level of the bar. One score is awarded for each pull up. One trial is given.
2. Flexed arm stand – to measure arm and shoulder strength
   Procedure – the adjusted bar is held with hand grasp. The student lifts her body with the help of assistance of testing personnel so that has chin reaches the bar level. The clasped time is taken as score. The score is nearest second.
3. Sit ups – to measure abdominal strength and endurance
   Procedure – Student is advised to lie on floor on his/her back keeping knees bent. The angle of knees should be around 90°. Further the student is advised to put fingers interlockedand put behind the head. The student curls up and touches the elbows to knees. The score is counted as maximum number of sit ups in 60 seconds.
4. 50 yards Dash – to measure speed
   Procedure – the student is advised to run 50 yards and time is recorded nearest to 10th of a second.
5. 600 yard run walk – to measure endurance.
   Procedure – the student is advised to run or walk 600 yards and time is recorded in minutes and seconds.

Answer 26.
Regular physical activity helps elderly people to enjoy life and increases longevity along through wellbeing.

1. Immune Function: A healthy, strong body fights off infection and sickness more easily and more quickly. Rather than sapping energy reserves entirely, recovery from an illness will take less of a toll on the body if the person exercises regularly.
2. Cardio-Respiratory and Cardiovascular Function: Frequent physical activity lowers the risk of heart disease and high blood pressure. If the elderly person has hypertension, exercise will help lower their blood pressure.
3. Bone Density and Risk of Osteoporosis: Exercise protects against loss in bone mass. Better bone density will reduce the risk of osteoporosis, lower the risk of falling and prevent broken bones. Post-menopausal women can lose as much as 2 percent bone mass each year, and men also lose bone mass as they age. Research done at Tufts University shows that strength training can dramatically reduce this loss, help restore bones, and contribute to better balance and less fractures.
4. Gastrointestinal Function: Regular exercise helps boost your metabolism and promotes the efficient elimination of waste and encourages digestive health.
5. Chronic Conditions and Cancer: Physical activity lowers risk of serious conditions such as Alzheimer’s disease and dementia, diabetes, obesity, heart disease, osteoporosis and colon cancer, to name a few. It also helps in the management of high cholesterol and arthritis pain.
6. Manage Stress, Improve Mood: Regular, moderate physical activity can help manage stress and improve your mood. And, being active on a regular basis may help reduce feelings of depression. Studies also suggest that exercise can improve or maintain some aspects of cognitive function, such as your ability to shift quickly between tasks, plan an activity, and ignore irrelevant information.
7. Prevent or Delay Disease: Scientists have found that staying physically active and exercising regularly can help prevent or delay many diseases and disabilities. In some cases, exercise is an effective treatment for many chronic conditions. For example, studies show that people with arthritis, heart disease, or diabetes benefit from regular exercise. Exercise also helps people with high blood pressure, balance problems, or difficulty walking.

Answer 12.
Correct measures of postural deformity:

• Most often, people with a mild curve will only need to be observed through screening by a medical practitioner.
• Exercise for muscle strength, flexibility and movement alignment are very effective.
• If the curve grows worse, a back brace may be worn until bone growth stops. Special exercises may be included. The brace dose not limit most activities
• In extreme cases, spinal surgery is performed to correct the curvature.
  If not treated what might happen?
• Medical problems can occur later in life such as
• Physical deformity • Heart and lung disorders • Pain and arthritic symptoms
  Process of screening:
• A simple 30-second observation of the back: first standing, then bending forward
• Screeners look for an unevenness of shoulders, hips, or one side of the back
• Shirts are removed for better viewing. Boys and girls are screened separately. Girls wear a two-piece bathing suit or a halter-top and shorts.
• Screening is usually done in the privacy of the school nurse’s office yearly.
• The school does not provide treatment, but can direct those who should have further attention to appropriate medical help.

Answer 13.
Spinal Curvature – Precautions:

• We should follow the appropriate posture of sitting, standing, walking and running.
• We should not carry heavy weights.
• Balanced diet should be taken.

Remedies:

• For scoliosis, bending exercises should be performed in appropriate side.
• Don’t carry heavy weights in one hand.
• For lordosis we should perform halasana and sit-ups
• For kyphosis, we should perform dhanurasana and chakrasana etc.

Flat foot – Precautions:

• Don’t not force the babies to walk at an early stage,
• Obesity should be avoided.
• Don’t walk bare feet.
• High heeled shoes should be avoid.

Remedies:

• Do rope skipping
• Jumping on toes
• Special shoes should be worn
• Perform tadasana or walk on toes

Answer 25.
Harvard step Fest was developed by Brouha and his associates in 1943. Purpose of this test is to measure cardiovascular fitness.
Procedure – The athlete is instructed to step up and down on the platform at a rate of 30 steps per minute for 5 minutes or until exhaustion occurs. The exhaustion is defined as when the athlete cannot maintain the stepping rate for 15 seconds and this can be administered by metronome. After the completion of stepping, the athlete is advised to step down. After this heart rate is measured between 1 to 1.5 minutes after finishing. The heart rate is the number of times the heart beats per minute. The heart rate can be measured by the method given ahead.
(i) Manual Method – the heart rate can be measured from any spot on the body at which any artery is closed to the surface so that a pulse can be felt. The most common place for measuring the heart rate is wrist and neck.
(ii) Monitor Method – a heart rate monitor or electro cardiogram can be used to measure more accurate heart rate. A heart rate monitor consists of a transmitter and receiver. The heart muscles transmit an electoral signal when they contract. The transmitter then sends an electromagnetic signal containing heart rate data to the wrist receiver which displays the heart rate.
(a) Short Form – In this, only heart rate is counted from 1-1.5 minutes after finishing.
(b) Long Form – In this, the heart rate is counted three times. Firstly from 1 to 1.5 minutes then between 2 to 2.5 minutes, and between 3 to 3.5 minutes.

Scoring:

• Fitness Index For Short Form = (100 x test duration in seconds) divided by (5.5 x pulse count between 1 and 1.5 minutes).
• Fitness Index For Long Form = (100 x test duration in seconds) divided by (2 x sum of heart beats in the recovery periods).
  Example of scoring fitness index:
  The test was conducted for an individual and following readings were recorded:-
  Total duration of stepping 300 seconds
  1-1.5 minutes = 95
  2- 2.5 minutes = 85
  3- 3.5 minutes = 75

1. Short form fitness score
   FI Score = (100×300)/(5.5×95) = 57.4
2. Long form fitness score
   FI Score = (100×300)/2(95 + 85 + 75) = 58.8
   Then by using following table the cardiovascular fitness is determined:

   Gender	Excellent	Above average	Average	Below average	Poor
   Male	Greater than 90	80-90	65-79	55-64	Less than 55
   Female	Greater than 86	76-86	61-75	50-60	Less than 50

The ice must be applied for 20 minutes 6-10 times in first 24 hours. Next day heat and massage is given to absorb the clot.
(iii) Management of Dislocation:

• Reduction – During this process, the doctor may try some gentle movements around the affected joint to help the bones back into position. In case of severe pain local anesthetic procedures are adopted.
• Immobilization – After getting the bones at normal position, the bones should be immobilized with a splint or sling for several weeks. The time for which splint or sling is to be used depends upon extent of damage to nerves, blood vessels and supporting tissues.
• Surgery – If reduction is not able to settle the joint then surgical technique can be used to move dislocated bones back into their correct positions. Even in case of ruptured nearby blood vessels, nerves or ligaments surgery is required.
• Rehabilitation – Rehabilitation process is started after the splint or sling is removed. For the dislocated joint the rehabilitation exercises should be designed in such a way the gradual load is given. The aim of rehabilitation is to restore normal range of motion and strength around the joint.

(iv) Management Of Fractures:

• First Aid for Closed Fracture – The injured part can be immobilized with the help of splint or sling as per the site.

6. India supports the role of developing countries should be represented in Security Council in decision making.

OR

India spends more on traditional security than non-traditional because

1. India has been involved in conflict with its neighbours as Pakistan in 1947-48, 1965, 1971 and 1999 and China in 1962.
2. In South Asian region, India is surrounded by nuclear armed countries. Hence, India’s decision to conduct nuclear test in 1990 was justified to safeguard national security.
3. India conducted its first nuclear detonation on 18 May 1974.

Though India has made efforts to develop its economy and an individual’s security from poverty but still it is lagging behind even now and we are supposed to make more efforts.

Answer 23.
Common but differentiated responsibilities mean that the state shall cooperate in the spirit of global partnership to conserve, protect and restore the health and integrity of the .earth’s ecosystem. As the states have common but differentiated responsibilities over various contributions of global environmental degradation. The developed countries acknowledge that the responsibility that they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the technological and financial resources they command.

We could implement the idea with the help of conventions and declarations:

1. The Rio-Summit held in June 1992 produced conventions dealing with climate change, biodiversity, forestry and recommended a list of developed practices called Agenda 21.
2. The 1992 United Nations Framework convention on climatic change (UNFCCC) also emphasised that the parties should act to protect the climate system on the basis of common but differentiated responsibilities.
3. An international agreement known as Kyoto Protocol set targets for industrialised countries to cut their greenhouse gas emissions which support for global warming.

OR

The impact of changing role of state in the developing countries in the light of globalisation can be summed up as follows:

1. Globalisation reduces the state capacity i.e. the ability of governments to do what they do.
2. Market becomes the prime concern to set down economic and social priorities.
3. Multinational companies effect on the decisions taken by government because their own interest fulfillment also depends on government policies.
4. The old welfare state is now giving way to more minimalist state to perform certain core functions as maintenance of law and order and the security.
5. State also withdraws from many of its welfare functions taken place at the level of
   economic and social well-being. .
6. To some extent developing countries have received a boost as a result of globalisation and became more strong and powerful clue to emergence of new technology.

Answer 24.
India has maintained good relations with all the post-communist countries, but the strongest relations are still those between Russia and India.

1. Indo-Russian relations are a significant aspect of India’s foreign policy. Their relations are embedded in history of trust and common interests and are matched by popular perceptions. For example, Indian heroes from Raj Kapoor to Amitabh Bachchan are household names in Russia and many post-Soviet countries.
2. Russia and India share a vision of multipolar world order i.e. co-existence of several world powers internationally, collective security, greater regionalism, democratisation with the decision-making through bodies like the UN.
3. More than 80 bilateral agreements have been experienced between India and Russia as a part of the Indo-Russia Strategic Agreement of 2001.
4. India has been benefitted from its relationship on the issues like Kashmir, energy supplies, sharing information on international terrorism, access to Central Asia and balanoing its relation with China.
5. Russia is also important for India’s nuclear energy plan and assisting India’s space industry by giving cryogenic rocket to India whenever needed.
6. Co-operation with Russia and its republics like Kazakhstan, Turkmenistan in the form of partnership and investment in oil fields has also benefitted India.
7. Russia is also “benefitted from India on ground of the second largest arms market.
   Indian military gets most of its hardware from Russia.
8. Russia and India have collaborated on various scientific projects also.

“We can identify three constraints on American Power” which were actually not in operation in the years following 9/11. Hence, the US could establish its hegemony. Recently all these constraints are slowly beginning to operate in the following ways:

1. The US bears institutional architecture in the American State itself. It refers division of powers between the three branches of government where American military’s executive branch can place significant brakes upon the unrestrained and immoderate exercise.
2. The second constraint on American hegemony emerges from open nature of American society. American society and suffering from a deep skepticism towards purposes and methods of government in America despite an imposition of particular perspectives on domestic opinion in the US. This is a huge constraint on US military action overseas.
3. The third constraint on US hegemony is the possession of NATO to moderate the exercise of the US hegemony today. The US has an enormous interest in keeping the alliance of democracies to follow the market economies alive and it may be possible to its allies in NATO to moderate the exercise of the US hegemony through their own i liberal policies to fullfiel their own ends.

1. Role of Pt. Nehru in setting the national agenda :
As the Prime Minister and Foreign Minister, Jawaharlal Nehru exercised profound influence in the formulation and implementation of India’s foreign policy from 1946 to 1964. The three major objectives of Nehru’s foreign policy were to preserve the . hard-earned sovereignty. Protect territorial integrity, and promote rapid economic development. Nehru wished to achieve these objectives through the strategy of non-alignment. There were, of course; Parties and groups in the country.
2. Role of Pt. Nehru in Afro-Asian unity :
Jawaharlal Nehru envisaged a crucial role for India in world affairs and in Asian _ affairs especially. His era was marked by the establishment of contacts between India and other newly independent states in Asia and Africa. Throughout the 1940s and 1950s, Nehru had been an ardent advocate of Asian unity. Under his leadership, India convened the Asian Relations Conference in march 1947, five months ahead of attaining its independence, and made earnest efforts for the early realisation of freedom of Indonesia from the Dutch colonial regime by convening an international conference in 1949 to support its freedom struggle.

Popular movements are the movements organised by dalits and farmers under the banner of various social organisations to voice their demands.
Issues related to women which brought social awareness among them:

1. Chipko movement spread across many parts of Uttarakhand and larger issues of ecological and economic exploitation were also raised. Government issued a ban on felling of tress in Himalayan region for fifteen years until green cover was fully restored. Active participation of women was also a very novel aspect of the movement.
2. Anti-arrack movement was the movement of rural women in Andhra Pradesh to protest against alcoholism, mafias and government. This movement focused on issues of sexual violence against women either within family or outside. Women joined the campaign against dowry and demanded personal and property laws based on gender  equality. These campaigns contributed a great deal in increasing social awareness as well as shifted from legal reforms to open social confrontations.
3. Throughout seventies and eighties, local fish workers’ organisations fought with the State governments over the issues of their livelihood. Fisheries being a State subject, the fish workers were mostly mobilised at the regional level. With the coming of policies of economic liberalisation in and around the mid eighties, these organisations were compelled to come together on a national level platform-the National Fishworkers’ Forum (NFF). Fish workers from Kerala took the main responsibility of mobilising fellow workers, including women workers of other states.

Answer 27.
Punjab Accord was an agreement signed between the then Prime Minister Rajiv Gandhi and Harchand Singh Longowal, the then President of Akali Dal in 1985 to be known as ‘Rajiv Gandhi Longowal Accord’ also to create normalcy in Punjab:

• Chandigarh would be transferred to Punjab.
  
  Rajiv Gandhi and Harchand Singh Longowal, signatories of Punjab Accord of 1985
• To appoint a separate commission to resolve border dispute between Punjab and Haryana.
• To set up a tribunal to settle down the sharing of Ravi-Beas river water among Punjab, Haryana and Rajasthan.
• To provide agreement for compensation to better treatment to those affected by militancy in Punjab.
• To withdraw the Armed Forces Special Power Act in Punjab.

But, peace could not be established easily in Punjab and resulted as follows:
(a) It led to many excesses by police and violation of human rights.
(b) It fragmented the Akali Dal.
(c) The President’s rule was imposed and normal political process was suspended.
(d) Hence, political process could not be restored in this atmosphere. Even during elections in 1992, only 24% electors turned out to vote.

Consequently above mentioned added to tension between Punjab and its neighbouring states.

Answers

Answer 1.
Government’s endeavours to spread education will lead to an increase in the quality of workforce. The production potential of the country would also increase. Economic value reflected is in terms of providing better quality of workforce. Also, this is expected to shift the PPC rightwards.

Answer 2.
Fixed cost remains constant at all levels of output. So, fixed cost curve is parallel to X-axis.

Answer 3.
(a) The application of fixed factor can be changed during long period.

Answer 4.
Loss of interest on his savings is the implicit cost of businessman.

Answer 5.

Marginal Opportunity Cost \(\left( MOC \right) =\frac { Loss\quad of\quad Output\quad of\quad Y\left( \triangle Y \right) }{ Gain\quad of\quad Output\quad of\quad X\left( \triangle X \right) } \)
Since, MOC is rising, therefore Production Possibility Curve (PPC) will be concave to origin.

Answer 6.
Difference between normal goods and inferior goods are:

Or
Due to changes in factors other than the price of the commodity concerned, if more quantity at the same price is demanded, then it is termed as increase in demand and is represented by the rightward shift in the demand curve.
Increase in demand can be explained better with the below mentioned example and diagram:

As it is clear from the above schedule that at the same price of ₹ 10, demand has increased from 20 to 25 units.

In the given diagram, demand increases from OQ to OQ₁ at the same price OP.

Answer 7.
Price ceiling refers to the maximum price of a commodity that the sellers can charge from the buyers. It is generally imposed on essential commodities like foodgrains and certain medicines.

Implications
Government fixes this price lower than the equilibrium market price, so that the concerned commodity remains within the reach of poorer sections of society. Due to this, following implications of price ceiling are seen:

1. Since ceiling price is lower than the equilibrium price, there is likely to be excess demand in the market, leading to shortage of commodity.
2. To make extra normal profits, sellers generally resort to black marketing.

Or
(i) When demand is perfectly elastic and supply decreases, there will be no change in price but the equilibrium quantity will decrease. The following diagram shows that when supply decreases from SS to S₁S₁, equilibrium price remains constant at OP but equilibrium quantity decreases from OQ to OQ₁.

(ii) When supply is perfectly inelastic and demand increases, the price of the commodity will increase but the equilibrium quantity of that commodity remains constant. The following diagram shows that when demand increases from DD to D₁D₁, the equilibrium price also increases from OP to OP₁ but equilibrium quantity of that commodity remains constant at OQ.

Answer 8.
Given, P_X ₹8 P_Y ₹8 MRS_XY = 8
Consumer’s equilibrium is attained where
\({ MRS }_{ XY }=\frac { { P }_{ X } }{ { P }_{ Y } } \Rightarrow 8>\frac { 8 }{ 8 } ;\)
∴ \({ MRS }_{ XY }>\frac { { P }_{ X } }{ { P }_{ Y } } \), so the consumer is not in equilibrium.
Here, consumer can attain equilibrium only when MRS_XY starts falling and becomes equal to \(\frac { { P }_{ X } }{ { P }_{ Y } } \) (on the assumption that \(\frac { { P }_{ X } }{ { P }_{ Y } } \) is constant). This happens only when consumer starts consuming more of X in place of Y so, that he moves downward to right along the IC.
So, if \({ MRS }_{ XY }=\frac { { P }_{ X } }{ { P }_{ Y } } \), then a rational consumer would react by substituting X for Y.

Answer 9.
A firm can sell more only by lowering the price in imperfect market forms such as monopoly and monopolistic competition. In these market forms, the Average Revenue (AR) curve is downward sloping. When AR curve is falling, Marginal Revenue (MR) is less than AR. Therefore, MR curve lies below the AR curve. The slope of MR is half the slope of AR.

It can be seen from the above diagram that at the mid-point of AR curve, MR is zero and below mid-point of AR, MR becomes negative.

Answer 10.
A producer is said to be in equilibrium when he is earning maximum profits and he has no tendency to change the level of output. Producer’s equilibrium under the following situations :

1. When Marginal Revenue is Greater than Marginal Cost (MR > MC) Under this situation, the producer will not be in equilibrium because at this point, the marginal revenues from the sale of an additional unit exceeds the marginal cost incurred in producing that good.
   As a result, it will be more profitable for the producer to expand the level of output till MR becomes equal to MC and MC exceeds MR beyond the point of equality.
2. When Marginal Revenue is Equal to Marginal Cost (MR = MC) Under this situation, the producer or
   firm may or may not be in equilibrium because :
   At this point of equality of MR and MC, if MC exceeds MR beyond the point of equality, only then the producer will be in equilibrium because MR = MC is necessary but not a sufficient condition of producers’ equilibrium. The producer will be in equilibrium only when following two conditions are satisfied simultaneously i.e.,
   MR = MC and MC must cut MR from below.

Answer 11.
The budget line of a consumer can change in the conditions discussed below:
(i) When Income of the Consumer Changes Assuming price to be constant, budget line will change with a change in consumer’s income in the following ways :
(a) When Income of the Consumer Increases When income of the consumer increases, with no change in the prices of good X and good Y, then there will be a parallel rightward shift in the budget line.

With increase in consumer’s income, budget line shifts from ab to a₁b₁.
(b) When Income of the Consumer Decreases When income of the consumer decreases, with no change in the price of good X and good Y, then there will be a parallel leftward shift in the budget line.

With decrease in consumer’s income, budget line shifts from ab to a₁b₁.
(ii) When Price of Good X Changes When price of good X changes and price of good Y and income of the consumer remains unchanged, then,
(a) increase in price of good X will lead to consumer buying less units of good X. The budget line will rotate leftwards from ab to ab₁.
(b) decrease in price of good X will lead to consumer buying more units of good X. The budget line will rotate rightwards from ab to ab₂

Budget line rotates inwards when price of good X rises and rotates outwards when price of good X falls.
(iii) When Price of Good Y Changes When price of good Y changes and price of good X and income of the consumer remains unchanged, then,
(a) increase in price of good Y will lead to consumer buying less units of good Y.
The budget line will rotate leftwards from ab to a₁b.
(b) decrease in price of good Y will lead to consumer buying more units of good Y.
The budget line will rotate rightwards from ab to a₂b.

Budget line rotates inwards when price of good Y rises and rotates outwards when price of good Y falls,
(iv) When Price of Both the Goods Increases Assuming consumer’s income to be constant, when price of both the goods increase, then budget line will shift leftwards from ab to a₁b₁.

Budget line shifts leftwards with increase in the prices of both the goods.
(v) When Prices of both the Goods Decreases Assuming consumer’s income to be constant, when price of both the goods decreases, then budget line will shift rightwards from ab to a₁b₁.

Budget line shifts rightwards with decrease in the prices of both the goods.
The economic value is to consume within one’s means.

Answer 12.
Product differentiation refers to the practice of differentiating products on lines of design, colour or
packaging. In monopolistic competition, rival firms sell products which are not perfect substitutes but close substitutes of each other e.g. Pepsodent and Colgate toothpaste are close substitutes of each other due to product differentiation in their ingredients.
The implications of monopolistic competition are as follows:

1. It allows firm to have a partial control over price of their product.
2. Elasticity of demand for a product tends to be high due to presence of close substitutes.
3. Consumer’s welfare is increased due to large variety of commodity.

Or
Equilibrium price refers to the price at which market demand is equal to market supply (i.e. there is no excess demand or excess supply). So, the price with ‘excess supply’ is not the equillibrium price.
This can be illustrated with the help of the following figure :

The given figure depicts, that excess supply is equal to AB=Q₁Q₂. It implies that market supply is greater than market demand.
This puts pressure on price (OP₁) to decline. The producers reduce the quantity supplied at the lower price OP from OQ₂ to OQ. The consumers react by increasing the quantity demanded from OQ₁ (at OP₁ price) to OQ (at OP price). Equilibrium is struck at point ‘E’. Thus, OP and OQ are the equilibrium price and equilibrium quantity respectively with no excess supply.

Section – B

Answer 13.
Fiscal discipline refers to a situation when fiscal deficit is within the manageable limits and it does not lead to high rate of inflation in the country.

Answer 14.
Revenue deficit indicates that government is unable to cover its day-to-day expenses which hampers the future growth.

Answer 15.
(a) Minimum reserve system is followed by Reserve Bank of India for issuing currency.

Answer 16.
Credit money refers to deposits with banks which are withdrawable through a cheque.

Answer 17.
If aggregate demand falls below full employment level, it will lead to deflationary situations in the economy.

In this figure, AD_FE = AD at full employment level
AD_IU = AD at involuntary unemployment level or below full employment level.
The point E is the equilibrium point, where AD = AS. But at the current levels, deficient demand situation (due to involuntary unemployment) of AD_IU, the Aggregate Demand is less than the actual supply in the economy. Hence, EF is the deflationary gap.
Deflationary Gap = Deficient Demand
= AD_FE – AD_IU = EF
Or
Margin requirement refers to the margin between the market value of the security provided by the borrower and the loan amount approved. When margin is lower, the borrowing capacity of the borrower is higher.

The Central Bank has the power to change this margin. When Central Bank lowers the margin, the borrowing capacity of the borrower increases. This raises consumption expenditure and Aggregate Demand (AD) also increases which helps in correcting deflationary gap.

Answer 18.
Given, \(\frac { MPC }{ MPS } =\frac { 3 }{ 1 } \)
Let MPC be 3x and MPS be 1x
Also, MPC + MPS=1
∴ 3x + 1x = 1 ⇒ 4x = 1
\(x=\frac { 1 }{ 4 } =025\)
Or MPS = x = 025
MPC = 3x = 3 x 025 = 0.75
Now, change in income (∆Y) = ₹ 8,000
\(K=\frac { 1 }{ 1-MPC } =\frac { 1 }{ 1-0.75 } =4\)
\(K=\frac { \triangle Y }{ \triangle / } \) ⇒ ∆Y = ∆/.K
8,000 = ∆/x 4 ⇒ ∆/ = ₹ 2,000
So, investment in the economy should rise by ₹ 2,000.
The economic value reflected is concern for increasing the productive capacity of the country.

Answer 19.
In a two sector economy, there are only two sectors of economic activity namely households and firms. Households supply factor services to firms and firms hire factor services from households. Households spend their entire income on consumption. Firms sell what is produced to the households.
There are two types of markets in this economy:
(i) Product Market Market for goods and services.
(ii) Factor Market Market for factors of production.

The above figure shows that

1. Total Production of Goods and Services by firms
   = Total Consumption of Goods and Services by Households
2. Factor Payments by Firms = Factor Incomes of Households
3. Consumption Expenditure of Households = Income of Firms
4. Thus, Real Flow of Production and Consumption of Firms and Households = Money Flows of Income
   and Expenditure of Firms and Households

Answer 20.
Bank rate refers to the minimum rate at which the Central Bank of a country giveS credit to the commercial banks without any collateral. Increase in the bank rate increases the rate of interest and the cost of borrowings goes up, which discourages borrowers from taking loans which reduces the ability of commercial banks to create credit. On the other hand, a decrease in the bank rate decreases the rate of interest and the cost of borrowings goes down, which encourages borrowers to demand more loans and credit is expanded.
Or
Under the Barter system of exchange, acts of sale and purchase of a good or service were to occur at the same point of time. To buy a thing, an individual must at the same time sell something needed by the other person. But with the introduction of money (as a medium of exchange), an individual can buy a good with money without selling anything at the same time. Likewise, he can sell a good for money without buying anything at the same time. Thus, with the introduction of money, acts of sale and purchase have been separated.

Answer 21.
Importance of government budget can be explained as follows:

1. It shows revenue deficit, fiscal deficit and primary deficit of the government budget which reflects the status of fiscal discipline in the country.
2. It reflects how the government is going to influence the allocation of resources in the country.
3. It points to the efforts of the government to achieve equality in the distribution of income and wealth.
4. It is used to correct the situations of inflationary/deflationary gap in the economy.

Answer 22.
Treatment assigned to the following while estimating national income are as follows:

1. Expenditure on adding a floor to building is included in national income because it is a part of investment expenditure.
2. Payment of fees to a lawyer engaged by a firm is not to be included in estimation of national income as it is treated as part of intermediate consumption.
3. Payment of interest by a government firm should be included while estimating national*income because it
   is a kind of factor payment.

Or
(i) By Product Method
Gross Domestic Product at Market Price (GDP_MP)
= Gross Value Added at Market Price in Primary Sector + Gross Value Added at Market Price in Secondary Sector + Gross Value Added at Market Price in Tertiary Sector
= 600 + 400 + 1,400
GDP_MP = ₹ 2,400 crore
Net National Product at Factor Cost (NNPfc) = GDP_MP + Net Factor Income from Abroad – Consumption of . Fixed Capital – Net Indirect Tax
=₹ 2,400 + 40 – 300 – 240 ⇒ ₹ 2,440 – 300 – 240
∴ NNP_FC = ₹ 1,900 crore

(ii) By Expenditure Method
Gross Domestic Product at Market Price (GDP_MP)
= Private Final Consumption Expenditure
+ Government Final Consumption Expenditure
+ Gross Domestic Capital Formation (Net Domestic Fixed Capital Formation + Consumption of Fixed Capital + Change in Stock) + Net Exports
= ₹ 1,500 + 300 + [440 + 300 + (-40)] + (-100)
= ₹ 1,800 + 700 -100 ⇒ ₹ 2,500 -100
∴ GDP_MP = ₹ 2,400 crore
Net National Product at Factor Cost (NNP_FC)
= GDP_MP – Net Indirect Tax + Net Factor Income from Abroad – Depreciation
= ₹ 2,400 – 240 + 40 – 300 ⇒ ₹ 2,440 – 540

Answer 23.
Difference between inflationary gap and deflationary gap are :

Two measures by which inflationary gap can be corrected:

1. Increase in bank rate
2. Increase in repo rate

Two measures by which deflationary gap can be corrected:

1. Decrease in bank rate
2. Decrease in repo rate

Answer 24.
(i) Fixed rate of exchange is not determined by the forces of demand and supply in the market. It is fixed or declared officially by the country’s concerned authority.
Such a rate of exchange has been associated with standard system during 1880-1914. According to this system, value of every currency is determined in terms of gold.
Accordingly, the ratio between gold value of the two currencies was fixed as exchange rate between those currencies.
For example,
Value of one dollar = 20 g of gold; Value of a rupee = 5 g of gold
Then, 1 $ = \(\frac { 20 }{ 5 } \) = ₹ 4
(ii) The main merits of flexible exchange rate are as follows :

• It eliminates problems of over-valuation and under-valuation of currencies as it is self adjusting and automatically removes the diseauilibrium in the Balance of Payments (BoP).
• It enhances the movement of ca *al across different parts of the world and promotes international growth.
• It enhances the opportunity for optimum utilisation of resources and raises the level of efficiency in the economy.

Answers

Section – A

Answer 1.
(b) inelastic

Answer 2.
Developmental needs are more in a underdeveloped economy and these have to be fulfilled with the help of limited resources. Thus, there is a need of efficient and effective utilisation of resources.

Answer 3.
(c) ₹ 56
Hint: AFC at 4 units =₹ 20,
∴ TFC = 20 x 4 = ₹ 80
AVC at 5 units = ₹ 40
∴ TVC at 5 units = 40 x 5 = ₹ 200
TC at 5 units = TFC + TVC = 80 + 200 = ₹ 280
ATC = \(\frac { 280 }{ 5 } \) =₹ 56

Answer 4.
Variable cost curve originates from the point of origin because when output is zero, variable cost is also zero.

Answer 5.
A consumer attains equilibrium, when = \(\frac { M{ U }_{ X } }{ M{ U }_{ M } } ={ P }_{ X }\)
Where, MU_X = Marginal Utility of Commodity X
MU_M = Marginal Utility of Money
P_X = Price of Commodity X
Substituting the given values, we get \(\frac { M{ U }_{ X } }{ 8 } =10\) 10 implying that, in a state of equilibrium, Akansha’s MU_X must be equal to 80 utils. If having consumed 4th ice-cream, Akansha’s MU_X = 80 utils, then she must stop consuming more. However, if MU_X > 80, then she should consume more ice-creams till MU_X reduces to 80 utils and in terms of its money worth is equal to price of ice cream.

Answer 6.
Economics as a Positive Science A positive science is that science in which analysis is confined to cause and effect relationship. It simply states, ’what is’ and not ‘what ought to be1′ It does not pass any value judgement regarding what is right or wrong. Positive economics is concerned with the facts about the economy, as they exist.
e.g. positive economics deals with questions like ’what are the causes of unemployment’, ‘why prices are increasing’ and so on.

Economics as a Normative Science Economics as a normative science is concerned with ’what ought to be’. It examines real economic events from moral and ethical angles and judges whether certain economic events are desirable or not. It passes value judgement and prescribes methods to correct undesirable happenings.
e.g. normative economics deals with opinions like ‘old-age pension should be stopped’, ’MGNREGA will bring an end to unemployment’ and so on.
Or
‘Choice of technique’ is the problem of ’How to produce’?
‘How to produce’? is the problem which refers to the problem relating the choice of technique. Broadly, there are two techniques of production:

1. Labour-intensive technique and
2. capital intensive technique.

Labour-intensive technique uses more of labour than capital (machines) and is cost effective, whereas capital-intensive technique uses more of capital (machines) than labour and promotes efficiency.
So, a business firm needs to choose among these two techniques such that it obtains a cost-effective as well as efficient relationship.

Answer 7.
Average Fixed Cost (AFC) can be obtained by dividing Total Fixed Cost (TFC) by the quantity of output (Q),
i. e.

\(AFC=\frac { TFC }{ Q } \)

Since, total fixed costs remain the same as output rises, Average Fixed Cost diminishes but never becomes zero.

As output rises, the Average Fixed Cost (AFC) goes on declining. The AFC curve is, therefore a downward sloping curve. AFC curve never touches either of the axis. Thus, the AFC curve takes the shape of rectangular hyperbola which shows that the area under the curve (i.e. total fixed cost) always remains the same.
Or
A competitive firm sells its output at a uniform price. The price or Average Revenue (AR) is constant and Marginal Revenue (MR) is also constant as it is equal to AR. The Total Revenue (TR) is the sum total of MR corresponding to different levels of output.

Since MR is constant, TR increases at a constant rate. Thus, TR is an upward sloping straight line. It passes through origin because when output is zero, TR is also zero.

Answer 8.
Suppose at price X, consumer is willing to buy 450 units of goods Y
Here, E_d = 2;P = 15; P₁ = ₹ X, ∆P = ₹ (X-15)
Q = 300 units, Q₁ = 450 units .
∆Q = (450 – 300) units = 150 units
Where, E_d = Price Elasticity of Demand
P = Actual Price, P₁ = New Price
Q = Actual Quantity, Q₁ = New Quantity
∆P = Change in Price,
∆Q = Change in Quantity

The consumer will purchase 450 units of good Y at the price of ₹ 11.25 per unit.

Answer 9.
Following factors lead to the emergence of oligopoly market:

1. Government Licensing The government may grant licenses only to a few firms for the production of a commodity, e.g. coal mining rights are given to some companies only.
2. Patent Rights Some firms acquire patent rights on account of their innovative product/ technology that restrict the entry of new firms.
   e g. A computerised method of running cash management account, being patented by a company.
3. Scale of Investment Scale of investment for certain products is so high that it becomes difficult for many companies to afford it which leads to concentration of market in the hands of few companies, e.g. Software and Automobile Industries.
4. Cartels Sometimes big companies collaborate or form cartels to gain the control over market.
   e.g. OPEC set-up in 1960 by the world’s five major oil producing countries: Iran, Iraq, Kuwait, Saudi Arabia and Venezuela.

Answer 10.
Producer’s equilibrium is that point at which a producer is getting maximum profit and he has no tendency to change his output. When Marginal Revenue (MR) is equal to Marginal Cost (MC) and marginal cost is rising beyond the point of equilibrium, at that point, the producer earns maximum profits.

Accordingly, producer’s equilibrium is struck at 5th unit of output because at output level of 2 and 5 units, both MR and MC are equal, which is equal to 5 in both the cases. But the producer is in equilibrium at 5th unit only where profit is maximum, i.e. 2. Also, beyond this level, Marginal Cost tends to rise.
Formulae Used
Total Revenue (TR) = Price (P) x Quantity (Q)
Marginal Revenue (MR) = TR_N – TR_N-1
Marginal Cost (MC) = TC_N – TC_N-1

Answer 11.
From the supply function, we have learnt that the minimum Average Cost (AC) is ₹ 20 and no firm would be ready to sell at price below minimum of AC. Hence, in the situation of free entry and exit, equilibrium price will always be equal to minimum AC. Hence, in this situation, equilibrium price will be P0 = ₹ 20 (equal to minimum AC)

At this price, market supply will be equal to market demand.
From the demand function, we can get the equilibrium quantity by substituting in the function the value of price q₀ = 800 – 20 = 780 units

At equilibrium price (P₀ = ₹ 20), each firm supplies = 10 + 20 = 30 units
Hence, equilibrium number of firms will be,\([{ N }_{ 0 }=\frac { { q }_{ 0 } }{ { q }_{ 0p } } =\frac { 780 }{ 30 } =26firm\)

Thus, given the market demand function and supply function of a firm when free entry and exit are allowed,
Equilibrium price = ? 20, Equilibrium quantity = 780 units, Total number of firms = 26
Or

1. P = 10 suggests that in the situation of free entry and exit, equilibrium price can neither be greater nor less than ₹ 10. If the market price becomes greater than ₹ 10, Excess supply emerges and price tends to fall till it becomes equal to ₹ 10. On the other hand, if market price becomes smaller than ₹ 10, excess demand emerges and price tends to rise till it reaches ? 10.
2. From the supply function, \({ q }_{ t }^{ s }\)= 0 for P < 10, we have learnt that the minimum Average Cost (AC) is ₹ 10. In the situation of free entry and exit, equilibrium price is always equal to minimum AC. Hence, in this case, market will be in equilibrium at the price of ₹ 10.
3. From the demand function, we can get the equilibrium quantity by substituting the value of price.
   q₀ = 590 – P = 590 -10 = 580 units
4. At equilibrium price (P0) = 10, each firm supplies q_0f = 8+ 5 x 10 = 58 units
   Hence, the number of firms required =\(\frac { 580 }{ 58 } =10firms\)

Answer 12.
The Law of Demand states that other things remaining constant, the quantity demanded of a commodity expands with fall in its price and contracts with a rise in its price. So, there is an inverse relationship between price and quantity demanded of a commodity. This is explained with the help of an imaginary schedule and cunve which is based on that imaginary schedule.

Exceptions to the Law The law will not hold good under following circumstances:

1. Conspicuous Consumption The Law of Demand will not apply in case of costly items such as diamonds. These commodities will be demanded, even if the prices have gone very high.
2. Ignorance If the consumer is not aware of the competitive price of the commodity, he may purchase
   more of the commodity even at higher price. Such ignorance of the buyers makes the Law of Demand ineffective.

No, I don’t think that law of demand explains the demand for gold in our country. In spite of continuously rising prices, demand for gold remains constant. It is because consumers believe that prices of gold will rise further in future and because of this their demand has not fallen in the present. In this case too, law of demand have failed due to high future expectation of price by the consumer.

Section – B

Answer 13.
Fraction of total deposit that each commercial bank must keep with themselves in liquid assets (cash, gold and unencumbered securities) is referred to as statutory liquidity ratio.

Answer 14.
Direct tax is that tax whose incidence and impact falls on the same person i.e. burden of such taxes cannot be shifted to others e.g. gift tax, corporation tax, income tax, etc.

Answer 15.
Time deposits are fixed or recurring deposits which have a fixed period of maturity. The term of deposit may vary. Cheques cannot be issued against them and they are not payable on demand but these deposits yield interest for the depositor.

Answer 16.
(c) Disinvestment is a source of capital receipt.

Answer 17.
The extent to which current aggregate demand becomes higher than the aggregate demand required for full employment, is termed as inflationary gap.

In the figure given below, full employment equilibrium is struck at point E. If the level of demand increases to AD,, it is in excess of what is required to maintain full employment. This causes inflation.
Inflationary Gap = EF (The difference between AD and AD₁).

Or
The extent to which aggregate demand falls short of aggregate supply to maintain full employment equilibrium is known as deficient demand. As shown in the diagram, deficient demand occurs when Aggregate Demand (AD) is less than what is required to maintain full employment in the economy. Full employment level of demand is indicated by AD₁. If demand level happens to be AD₂ the gap between AD₁ and AD₂, equal to ab, represents deficient demand.

Answer 18.
Let Average Propensity to Save (APS) = 2x
Average Propensity to Consume (APC) = 7x
Now, APS + APC = 1
2x + 7x = 1
9x = 1
\(x=\frac { 1 }{ 9 } \)

Answer 19.
Net Value Added at Factor Cost (NVAFC) = Sales + Change in Stock – Purchase of Raw Materials – Consumption of Fixed Capital + Subsidies =
500 + (-20) – 250 – 40 + 30
= 530 – 310 = ₹ 220 lakhs

Answer 20.
Under open market operations, RBI purchases or sells government securities to general public for the purpose of increasing or decreasing the stock of money in an economy. The purchase or sale of securities controls the money in the hands of public as they deposit or withdraw the money from commercial banks. Thus, money creation by commercial banks get affected.

Suppose, the Central Bank purchase securities of ₹ 1,000 from a bond holder by issuing a cheque. The seller of the bond produces this cheque of ₹ 1,000 to his commercial bank, fhe commercial bank credits the account of the seller by ₹ 1,000 and the deposits of the bank goes up by ₹ 1,000, which is a liability for the bank. On the other hand, the assets of the commercial bank also goes up as the cheque in its possession is a claim on the Central Bank.

Thus, purchase of security increases the money creation of commercial banks and similarly sale of securities decreases the credit creation of commercial banks. Thus, the Central Bank controls the process of money creation by commercial banks through open market operations.

Answer 21.
The two significance of public expenditure are as follows:

1. Increases Economic Growth Public expenditure accelerates the process of economic growth. This is of unique importance particularly, in the context of developing countries like India. Public expenditure helps in establishing new industries. It ensures development of public overhead cost like the construction of roads, dams, bridges, etc.
2. Increases Economic Welfare Public expenditure increases economic welfare. This happens particularly when public expenditure is directed towards poverty eradication, as well as, health and education for the poorer sections of the society. Such expenditures reduce economic divide between ‘have’ and ‘have-nots’ and thereby promotes social welfare.

Or
Following are the implications of large fiscal deficit:

1. National Debt Fiscal deficit leads to national debt as government resorts to borrowings to combat the deficit. National debt is a burden on future generations. Therefore, future generations inherit a economy which is under high pressure of mounting borrowings.
2. Low GDP Growth In case of large fiscal deficit, a significant percentage of national income is used up to pay the’past debts and very less is spent on infrastructural expansion, therefore, GDP growth of the economy remains low.
3. Crowding-out Effect High fiscal deficit increases borrowings by the government from the money market which reduces availability of funds for private entrepreneurs. Shortage of funds leads to high rate of interest which lowers the level of investment in the economy. Thus, economy slips into state of economic slowdown. This is known as crowding-out effect.
4. Erosion of Government Credibility High fiscal deficit erodes credibility of the government in domestic as well as international market, ‘credit rating’ of the government is lowered and global investors start withdrawing their investment from domestic economy.

Answer 22.
The counting of the value of commodity more than once is called double counting. This leads to over estimation of the value of goods and services produced. Thus, the importance of avoiding double counting lies in correct estimation of the value of domestic product, e.g. a farmer produces one tonne of wheat and sells it for ₹ 400 in the market to a flour mill.

The flour mill sells it for ₹ 600 to the baker. The baker sells the bread to the shopkeeper for ₹ 800. The shopkeeper sells the entire bread to the final consumers for ₹ 900. Thus,
Value of Output = ₹ (400 + 600 + 800 + 900) = ₹ 2,700

In fact, the value of the wheat is counted four times, the value of services of the miller thrice and the value of services by the baker twice.
In other words, the value of wheat and value of services of the miller and of the baker have been counted more than once. The counting of the value of commodity more than once is called double counting. To avoid the problem of double counting, following two methods are used:

1. Final Output Method According to this method, the value of intermediate goods is not considered. Only the value of final goods and services is considered. In the above example, the value of final goods, i.e. bread is ? 900.
2. Value Added Method Another method to avoid the problem of double counting is to estimate the total value added at each stage of production. In the above example, the value added at each stage of production is ₹ (400 + 200 + 200 +100)= ₹ 900.

Or

1. It will not be included in domestic product of India as this income is earned outside the domestic (economic) territory of India.
2. It will not be a part of domestic product of India as embassy of Japan in India is not a part of domestic territory of India. Hence, this income is not earned within the domestic territory of India.
3. It will be included in domestic product of India as the branch of American bank is located within the domestic territory of India. So, it is income earned within the domestic territory of India.
4. It will be part of domestic product of India because this income is earned within the domestic territory of India. Indian Embassy in Korea is treated as located within the domestic territory of India.

Answer 23.
If Aggregate Demand (AD) is less than Aggregate Supply (AS), then economy is not in equilibrium because an economy is in equilibrium when AS = AD.
When AD < AS, flow of goods and services in the economy tends to exceed their demand. As a result, some of the goods would remain unsold.
To clear unwanted stocks, the producers would plan a cut in production. Consequently, AS would reduce to become equal to AD. This is how AS adapts itself to AD.

In the above figure, equilibrium is struck at point E
where, AD = AS. At point Ev Aggregate Supply exceeds Aggregate Demand (AS > AD).
It will cause following changes in the economy:

1. Stocks of the producers would be in excess of the desired limit.
2. Desired level of output for the subsequent year will face a cut and profits will start shrinking.
3. Levels of income and employment will tend to shrink to the point where, S = l, corresponding to point E in the diagram.
   Thus, the economy will come back to the state of equilibrium.

Answer 24.

1. False, as current account of balance of payments account also records unilateral transfers.
2. True, as all kinds of foreign investments (foreign direct investments and portfolio investments) are included in the capital account of balance of payments.
3. False, as improvement in the exchange rate of a country’s currency implies that less rupees are to be paid for a dollar than before. It points to the relative strength of the Indian rupee in the international market. However, for a developing country like India, it is not always desired. It would mean that US, now can buy less Indian goods for a dollar than before, which might cut US demand for the Indian goods i.e., it leads to fall in exports from India.
4. True, a rise in foreign exchange rate causes a rise in its supply because, there is a direct relation or positive relation between foreign exchange rate and supply of foreign exchange. As with the rise in exchange rate, foreign currency can buy more units of domestic good with the same amount, therefore it leads to increase in supply of foreign exchange.
