Answer 2

Given:

✰ In a certain year, the population of India was about 98 crore.

✰ It increases by 2%.

To find:

✠ What will be its population after year?

Solution:

Let's understand the concept first!

• We know that in a certain year the population of India was about it increased by 2%, so we will add 2% to the population of India in a certain year, that is 98 crore to get the population after year.

• First we have to convert 2 percent into simple decimal number. To convert percent into simple decimal number we will follow the following steps:

1. Divide the percentage by under 100 then remove the percentage sign.
2. Multiply the given fraction by the the population of India in a certain year i.e, 98 crore.

Let's find out...✧

⟹ Percentage of population increased = 2%

⟹ Number of population increased = 2% of 98 crore

⟹ Number of population increased = 2/100 × 98 crore

⟹ Number of population increased = 2/100 × 980000000

⟹ Number of population increased = 2 × 9800000

⟹ Number of population increased = 19600000

⟹ Number of population increased = 1.96 crore

Now,

We will add Number of population increased to the population of India in a certain year to find the population of India after year.

➤ The population of India after year = The population of India in a certain year + Number of population increased

➤ The population of India after year = ( 98 + 1.96 )crore

➤ The population of India after year = 99.96 crore

∴ 99.96 crore will be its population after year.
