**Question 1.**

**Solution:**

We have :

**Question 2.**

**Solution:**

(i) Let x% of 1 kg be 125 g

**Question 3.**

**Solution:**

**Question 4.**

**Solution:**

(i) Let x be the required number.

**Question 5.**

**Solution:**

Let x be the number

The number is increased by 10%

Increased number = 110% of x

**Question 6.**

**Solution:**

The present value of the machine = ₹ 10000

The decrease in its value after the 1 st year = 10% of ₹ 10000

\(\frac { 10 }{ 100 }\) x 10000 = ₹ 1000

The depreciated value of the machine after the 1 st year = ₹ (10000 – 1000) = ₹ 9000

The decrease in its value after th 2nd year = 10% of ₹ 9000

\(\frac { 10 }{ 100 }\) x 9000 = 900

The depreciated value of the machine after the 2nd year = ₹ (9000 – 900) = ₹ 8100

Hence, the value of the machine after two years will be ₹ 8100.

**Question 7.**

**Solution:**

The present population of the town = 16000

Increase in population after 1 year = 5% of 16000

= (\(\frac { 5 }{ 100 }\) x 16000) = 800

Thus, population after one year = 16000 + 800 = 16800

Increase in population after 2 years = 5% of 16800

= \(\frac { 5 }{ 100 }\) x 16800 = 840

Population after two years = 16800 + 840 = 17640

Hence, the population of the town after two years will be 17,640.

**Question 8.**

**Solution:**

Let us assume that the original price of the tea set is Increase in price = 5%

So, value increased on the tea set = 5% of ₹ x

Hence, the original price of the tea set is ₹ 420.

**Mark (✓) against the correct answer in each of the following :**

**Solution:**

**Question 10.**

**Solution:**

(c) 12

Given that x% of 75 = 12

**Question 11.**

**Solution:**

(c) 25

Let the number be x. Then, we have:

120% of x = increased number

**Question 12.**

**Solution:**

(d) 180

Let the required number be x.

Then, we have :

5% of x = 9

**Question 13.**

**Solution:**

(a) 60

Let the number be x According to question, we get:

(35 % of x) + 39 = x

**Question 14.**

**Solution:**

(c) 500

Let x be the maximum marks Pass marks = (160 + 20) = 180

36 % of x = 180

**Question 15.**

**Solution:**

(i) 3 : 4 = (75) %

Explanation:

3 : 4 = \(\frac { 3 }{ 4 }\)

= (\(\frac { 3 }{ 4 }\) x 100) %

= (3 x 25)% = 75%

(ii) 0.75 = (75)%

Explanation : (0.75 x 100)% = 75%

(iii) 6% = 0.06 (express in decimals)

Explanation :

6% = \(\frac { 6 }{ 100 }\) = 0.06

(iv) If x decreased by 40% gives 135, then x = 225

Explanation :

Let the number be x.

According to question, we have :

x – 40% of x = 135
