Question

The population increases by 13% annually. If the current population is 43,000, what will it be after 3 years? (in approx.)

A.

72,045

B.

56,045

C.

52,045

D.

62,045

Correct option is D

Given:
Current population = 43000
Annual increase rate = 13%
Time period = 3 years
Formula Used:
Final Population = Initial Population × (1 + Rate ÷ 100) raised to the power of Time
Solution:
Substitute the given values into the population growth formula:
A = 43000 × (1+13100)3(1 + \frac{13}{100})^3​​
A = 43000 × (1.13)3(1.13)^3​​
A = 43000 × 1.442897 = 62044.57
Rounding to the nearest whole number gives 62045.
Final Answer
So the correct answer is (d)
