Question

The population of a city was 20,000 in the year 1997 . It increased at the rate of 5% p.a. Find the population at the end of the year 2000. ​

Answer 1

We have,

P = 20,000

R = 5%

T = 3 years

Amount =

$20000(1 + \frac{5}{100})^{3}$

$20000( \frac{105}{100})^{3}$

= 23,52.5

Hence this is the answer.

Hope it helps ❄️
