**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

10100 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

10100 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

= (5100 x 16000) = 800

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

Increase in population after 2 years = 5% of 16800

= 5100 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.
