The population of the 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?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 41,375.
Given that
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%
Now,
The net increment of the population in one year = 12.7 - 2.7 = 10%
The population increased after 3 years = 125000 × (1.1)3 = 125000 × 1.331 = 166375
Hence, The population increase in 3 years = 166375 - 125000 = 41375
