Question

The population of a small village increased by 8% annually if its present population is 23328 then the population 2 years ago was

Answer 1

Since, the present population = 23328

The population of a small village increased by 8% annually.

We have to determine the population 2 years ago.

Firstly, we will calculate the population of one year ago.

It is given by the formula $P \times \frac{100}{r+100}$ where 'r' is the percentage increase.

Population one year ago = $23328 \times \frac{100}{108}$

= 21600

Now, Population 2  years ago = $21600 \times \frac{100}{108}$

= 20,000

Therefore, the population 2 years ago was 20,000.
