Question

The population of a town was 3600 three years back. It is 4800 right now. . What is the rate of growth of population, if it has been constant over the years and has been compounding annually?

Options:

A . 15%

B . 5%

C . 12%

D . 10%

Answer: Option D
:
D
Option (d)
Conventional approach :

F i n a l V a l u e = I n i t i a l V a l u e {(1 + \frac{r}{100})}^{t}

Thus, rate

= {(\frac{F V}{I V})}^{\frac{1}{t}} - 1

\Rightarrow \frac{F V}{I V} = \frac{48}{36} = 1.33

Going from answer options
If 10 is the answer

{1.1}^{3} = 11^{2} \times 11 = 12 \times 11 \approx 1.33

Therefore r is approximately

10 % .
