Question : The population of a town is 1,25,000. If the annual birth rate is 12.7% and the annual death rate is 2.7%, how much will the population increase after 3 years?

Option 1: 43,285

Option 2: 41,375

Option 3: 42,565

Option 4: 40,275

Team Careers360 18th Jan, 2024

Correct Answer: 41,375


Solution : The present population, $P$ = 1,25,000
Increase rate, $r$ = 12.7% – 2.7% = 10%
Time, $n$ = 3 years
Total population = $P(1+\frac{r}{100})^{n}$
= $125000(1+\frac{10}{100})^3$
= $125000(\frac{11}{10})^3$
= $125000×\frac{11}{10}×\frac{11}{10}×\frac{11}{10}$
= $166375$
$\therefore$ Population increase = 166375 – 125000 = 41,375
Hence, the correct answer
