Answer 4.
(c) Maximum

Answer 5.
Economic problem arises due to the following reasons :

  1. Human “Wants are Unlimited Human wants are unlimited as it is a repetitive process in which wants get increased by consuming goods and sen/ices. Fulfillment of one want leads to the surfacement of another want.
  2. Resources are Limited Resources are limited in supply in relation to their demand. Scarcity is the basic feature of every economy. No economy can be self-sufficient in everything. Scarcity is a universal phenomenon, which continues indefinitely. The scarcity of resources creates economic problem for every country in the world.
  3. Resources have Alternative Uses The resources are not only scarce in supply but they also have alternative uses. e.g. land can be used to produce wheat or to rice or to build a hospital or a school. A choice between the alternative uses of land has to be made. This problem of choice leads to an economic problem.

Import substitution policy means producing goods in the country rather than importing from rest of the world. To produce more output, now inputs are being imported which increases the resources of the country. Consequently, production possibility curve would shift right from ab to a1b1.

Answer 6.
The consumer will purchase 4 units because at this consumption level, Marginal Utility (MU) is equal to the price. At consumption level of less than 4 units, MU is greater than price. Therefore, there is a scope of increasing gain by purchasing more. If he buys more than 4 units, MU becomes less than the price. Therefore, there is a scope of increasing gain by purchasing less, so consumer maximises satisfaction at 4 units of consumption of commodity X.

Answer 7.
The effect of the following on elasticity of supply of the good is as follows:

  1. Nature of Inputs Used The Elasticity of Supply depends on the nature of inputs used for the production of a commodity. If commonly available inputs are used, supply will be elastic, but in case of scarcely available inputs, the supply will be inelastic.
  2. Technique of Production In case of production of a commodity, supply will be less elastic if it involves the use of a complex and expensive technology. On the other hand, use of a simple technology facilitates quicker changes in output and supply.

Difference between short-run production function and long-run production function are:

Basis Short-run Production Function Long-run Production Function
Nature of factors Some factors are variable while ” others are fixed. All factors are variable.
Proportions type Short-period production function is of variable proportions type. Long-period production function is of constant proportions type.
Scale of output Scale of output remains constant. Scale of output changes.
Study of output behaviour Behaviour of output is studied with reference to ‘Returns to a factor’ or ‘Law of Variable Proportions. Behaviour of output is studied with reference to ‘Returns to scale’.

Answer 8.
Given, Percentage change in price = 10%,
Initial Quantity (Q) = 500 units
New Quantity = 400 units
Change in Quantity (∆Q) = 400 – 500 = -100 units
Percentage change in quantity demanded
CBSE Sample Papers for Class 12 Economics Paper 6 2

Answer 9.
(i) Very Large Number of Buyers and Sellers A perfectly competitive market is dominated by very large number of buyers and sellers of a commodity. It means that there is no such buyer or seller in the market whose purchase or sale is so large as to impact the total sale or purchase in the market. Each buyer and seller has only a fractional share in the market demand and market supply respectively. Each buyer and seller has to accept the price as it is in the .market. Therefore, it is said that a firm under perfect competition is a price taker not a price maker.

(ii) Freedom of Entry and Exit of Firm Under perfect competition, a firm can enter or leave the industry anytime. In order to analyse the implications of this feature, we need to focus on short period and long period situation. Short period by definition, is too short for an existing firm to leave the industry or for a new firm to join the industry. Accordingly, the significance of this feature is restricted only to long period situations. Because of free entry and exit, firms in the long-run earn only normal profits. In case, extra normal profits are earned, new firms will join the industry. In this case, market supply will increase, market price will fall and extra normal profits will be wiped out. In case of extra normal losses, some of the existing firms will leave the industry. Market supply will decrease, market price will increase and extra normal losses will be wiped out. Hence, there will be neither supernormal profits nor losses in the long-run.

Answer 10.
Equilibrium price is determined at a point where market demand is equal to market supply. Other things being equal, equilibrium price increases with an increase in demand and falls with a decrease in demand as shown in the following figure:
CBSE Sample Papers for Class 12 Economics Paper 6 3

In the given figure, DD is the initial demand curve and SS is the supply curve. Initially, the equilibrium point is E. Corresponding to this point, equilibrium price is OP.
As demand increases, demand curve DD shifts rightwards to D1D1. Supply remaining the same, equilibrium point shifts to E1. At this point, the equilibrium price is OP1. which is higher than OP. As demand decreases, demand curve DD shifts leftwards to D2D2. Supply remaining the same, equilibrium point shifts to E2. At this point, the equilibrium price is OP2, which is lower than OP.

Answer 11.
Price elasticity of demand measures the degree of responsiveness of quantity demanded of a commodity to a change in its price. Price Elasticity of Demand for a commodity is defined as the percentage change in quantity demanded for the commodity divided by the percentage change in its price.
Some of the important determinants of price elasticity of demand are as follows: (any five)

  1. Nature of the Commodity Nature of the commodity is an important determinant of the price Elasticity of Demand. Necessities like food items and prestige goods have an inelastic demand, while luxuries and comforts have comparatively elastic demand.
  2. Availability of Substitutes The demand for commodities having close substitutes is very elastic because if there is an increase in the price of the commodity, their people will start using substitute commodities.
  3. Postponement of Consumption The demand for commodities is elastic, whose consumption can be postponed for sometime such as the demand of television, otherwise it is inelastic as in the case of medicines.
  4. Different Uses of the Commodity A commodity which has several uses will have an elastic demand. On the other hand, a commodity having only one use will have inelastic demand, e.g. milk, steel, etc have elastic demand because they can be put to several uses.
  5. Time Period Generally, longer the duration of period, greater will be the elasticity of demand because consumer have enough time to adjust their demand and vice-versa.
  6. Habits If consumers are habituated of some commodities, the demand for such commodities will usually be inelastic, e.g. alcohol.
  7. Proportion of Income Spent on the Goods Items such as toothpaste, needle will have an inelastic demand as consumers spend a small proportion of their income on such items. On the other hand, goods on which the consumers spend a large proportion of their income (cloth, food, etc) tend to have elastic demand.

Consumer’s equilibrium is a point where budget line is tangent to Indifference Curve (IC) or equilibrium is achieved where slope of Indifference Curve is equal to the slope of budget line or price line.
Two conditions of the consumer’s equilibrium are given below:
(i) \(XY=\frac { { P }_{ X } }{ { P }_{ Y } } \)
(ii) At the point of equilibrium, Indifference Curve must be convex to the origin. It implies that at the point of equilibrium, MRS must be diminishing.
CBSE Sample Papers for Class 12 Economics Paper 6 4
In the given diagram, E is the equilibrium point at which budget line touches the higher Indifference Curve IC2. Points ’A’ and ‘B’ lie on IC1, which offers lower level of satisfaction to the consumer and IC3 is not affordable as per the income of consumer and prices of the two goods.
So, the consumer is at equilibrium at point F’ only, where the indifference curve is tanget to the budget line.MM.

Answer 12.

  1. False, because when Marginal Revenue (MR) is constant, Total Revenue (TR) is increasing at a constant rate. Only when Marginal Revenue is zero, Total Revenue is constant.
  2. False, Average Variable Cost (AVC) can fall even when Marginal Cost (MC) starts rising. In the figure given, MC is at its minimum at point ‘a’ and AVC is at its minimum at point Between points ‘a’ to ‘b’, MC is rising, but AVC is falling.
    CBSE Sample Papers for Class 12 Economics Paper 6 5
  3. True, because point of inflexion is a point from where slope of Total Product (TP) changes. And, Slope of TP=MP. Therefore, from this point, MP stops increasing and starts diminishing.

Answer 13.
Capital expenditure of the government budget refers to those expenditures of the government which either increase assets or reduce liabilities of the government.

Answer 14.
(c) Sales tax because it is not levied directly on the income of the consumer or earner.

Answer 15.
We know that,
Money created
= Deposits of Commercial Banks x \(\frac { 1 }{ LRR } \)
\(50,00,000=1,00,000\times \frac { 1 }{ LRR } \)
⇒ \(LRR=\frac { 1 }{ 50,00,000 } \) = 0.02 or 2%

Answer 16.
The components of M1 measurement of money supply (M1)=Currency (including notes and coins held by people) + Demand Deposits + Other Demand Deposits

Answer 17.
The implications of this statement are as follows:

  1. Aggregate demand is equal to aggregate supply in country ‘Z’.
  2. In country ’Z’, resources are being utilised in an optimum manner.
    Economic value being followed is that of best use of country’s resources.

Answer 18.
No, I do not agree. The term investment demand refers to the demand for real investment and not financial investment. Real investment is concerned with the increase in stock of capital assets such as tools, equipments, inventories and also increase in stock of consumer goods. Thus, it does not include investment in shares and securities.
The functional relationship between the consumption expenditure and the income is known as consumption function. Symbolically,
C = f (Y), which is read as, ‘Consumption is a function of income’.
Consumption function in terms of an algebric expression can be written as:
\(C=\overline { C } +bY\)
Where, C = Consumption expenditure
\(\overline { C } \) = Autonomous consumption at zero level of income
b = Marginal Propensity to Consume
Y = Income
Let us understand it with the help of a diagram.
CBSE Sample Papers for Class 12 Economics Paper 6 6
In the above diagram, point B represents the break-even point, where the consumption expenditure is equal to the income. To the left of point S, consumption is greater than income and to the right of point 6, consumption is less than income.

Answer 19.
Real Gross Domestic Product = ₹ 3,000, and Price Index = 175
We know that,
Price Index = \(\frac { Nominal\quad GDP }{ Real\quad GDP } \times 100\)
\(\Rightarrow 175=\frac { Nominal\quad GDP }{ 3,000 } \times 100\)
Norminal GDP = 175 x 30
=₹ 5,250
The price index of 175 indicates that as compared to the base year, the prices have increased by 75%. in current year

Answer 20.
Double Coincidence of Wants Barter system can only work, when both the persons are ready to exchange each other’s goods. For example, if a person has surplus rice and he wants wheat then he will have to find a person who has surplus wheat and wants rice. But usually this type of double coincidence is rare, especially in modern times.

Money has eliminated double coincidence of wants. In modern times, the buyer buys goods for money and the seller sells goods for money. So, the person having surplus rice can sell it in the market for money and from that money he can purchase wheat. So, money facilitates exchange of goods and services and helps in carrying on trade smoothly.
The various forms that money took during the process of evolution are discussed below:

  1. Commodity Money All sorts of commodities like pearls, sea-shells, salt etc have been used as a medium of exchange.
  2. Animal Money Animals such as cow, goat, etc were used as a medium of exchange. .
  3. Metallic Money Money made from metals like gold, silver, copper etc was called metallic money.
  4. Paper Money Money made of paper is known as paper money.
  5. Credit Money It refers to bank deposits with banks which are withdrawable through a cheque.
  6. Plastic Money It is the modern form of money in the form of debit and credit cards.
  7. Virtual Money It is the latest form of money which exists in web world. Bit coin is the example of virtual’money.

Answer 21.
With the efforts of government in raising educational and health related services, level of health and education of poor people is expected to rise. This leads to a rise in human capital formation.
Efficiency of workers is expected to rise with improvement in their health and with improvement in their education, skill formation will take place.
Consequently, the level of technology tends to scale up due to which more research and innovations are facilitated.
Higher level of output is achieved with the same level of inputs. So, Production Possibility Curve (PPC) tends to shift to the right.

Answer 22.
(i) By Income Method
Gross National Product at Factor Cost = Compensation of Employees + Rent + Interest + Profits ‘ + Net Factor Income from Abroad + Consumption of Fixed Capital
= 1,850 + 400 + 500 + 1,100 + (- 50) + 100
= 3,950 – 50 = ₹ 3,900 crore
(ii) By Expenditure Method
Gross National Product at Factor Cost = Private Final Consumption Expenditure + Government Final Consumption Expenditure + Net Domestic Capital Formation + Consumption of Fixed Capital + Net Exports + Net Factor Income from Abroad – Net Indirect Taxes
= 2,600 + 1,100+ 500 + 100 + (-100) + (-50) – 250
= 4,300 – 400 = ₹ 3,900 crore
The economic value involved in estimation of national income is to assess the level of economic development in the country.

Answer 23.
Consumption Function (C) =200 + 0.75 Y
Suppose, Income (Y) in the economy is ₹ 400, ₹ 500 or ₹ 600
When Y = 400
C= 200 + 0.75 x 400 = ₹ 500
When, Y = 500
C= 200 + 0.75 x 500 = ₹ 575
When Y = 600
C= 200 + 0.75 x 600 = ₹ 650

Income (Y) Consumption (C) APC (C /Y)
400 500 500/400 = 1.25
500 575 575/500 = 1.15
600 650 650/600 = 1.08

From the above table, it is clear that as income rises, Average Propensity to Consume (APC) decreases.
Therefore, as shown in the given example as income increases from ₹ 400 to ₹ 500 to ₹ 600,
APC decreases from 1.25 to 1.15 to 1.08, respectively.
(i) Investment Expenditure Substituting the value of
Y in saving function,
We get
S = -200+ 0.25 x 2,000 = ₹ 300
At equilibrium level of income, S = /
So, / =₹ 300
Thus, investment expenditure at equilibrium level of income is ₹ 300.
where, S = Savings
/ = Investments, Y = National Income/Income
(ii) Autonomous Consumption
Consumption + Saving = Income … (i)
Autonomous consumption refers to that level of consumption expenditure where income is zero. Flere, if income (Y) = 0, Saving (S) = -200 Putting these value in equation (i), We get Consumption + (- 200) = 0
⇒ Consumption = ₹ 200 So, Autonomous Consumption = ₹ 200
(iii) investment Multiplier \(K=\frac { 1 }{ MPS } \)
From saving function, we know that
Marginal Propensity to Save (MPS) = 025
Investment Multiplier (K) = \(\frac { 1 }{ 0.25 } =4\)

Answer 24.
(i) There is no direct impact on national income of a country with change in exchange rate. But change in exchange rate has an indirect impact on national income. When exchange rate rises, domestic currency depreciates. The foreign countries can now purchase more quantity of goods and services from the same amount of foreign currency from the domestic country. Imports tends to fall and exports tend to rise. Accordingly, aggregate demand tends to rise. A rise in AD may lead to a rise in national income.

(ii) Difference between depreciation and devaluation of currency are:

Basis Depreciation of Currency Devaluation of Currency
Market forces of demand and supply Depreciation of foreign currency is determined by market forces of demand and supply. Devaluation of foreign currency is not determined by market forces of demand and supply.
Government intervention There is generally no direct intervention of government. Devaluation is generally done by government itself.
Planning It is not planned at all. It is generally planned by government.
