In a decade, a town's population grew from 1,75,000 to 2,62,500. What is the average annual percentage increase in population?
Answer & explanation
Correct answer: option 3
Increase in population in a decade = 262500 - 175000 = 87500
1 decade = 10 years
Population increase in 1 year = \(\frac{87500}{10}\) = 8750
Required percentage = \(\frac{8750}{175000}\) × 100
= 5%
So , Average annual increase in population = 5%
