Question

The present population of a city is $15000$. If it increases at the rate of $4\%$ per annum. Find its population after $2$ years.

• A. $16224$
• B. $26224$
• C. $36224$
• D. $46224$

Answer 1

The correct option is A $16224$

Given, $P=15000,r=4\%,n=2$ years

Population after $2$ years $=$ $P\left[\right(1+\frac{R}{100}{)}^2]$
$=15000{\left[\right(1+\frac{4}{100})}^2]$
$=15000\times 1.0816$

$=16224$
Population after $2$ years is $16224$.
