Question

The population of a town is increasing at the annual growth rate of 5%. If the present population is 1,60,000 then what will be population 4 years later?​

Answer 1

Let, the Population will be x

Then, according to the question :

$160000 \times \frac{(100 + 5)}{100} \times \frac{(100 + 5)}{100} \times \frac{(100 + 5)}{100 } \times \frac{(100 + 5)}{100} = x \\ \\ = > 160000 \times \frac{105}{100} \times \frac{105}{100} \times \frac{105}{100} \times \frac{105}{100} = x \\ \\ = > x = 194481$

So, the population after 4 years will be 194481

I hope it will be helpful for you ☺
