Question

The population of a town increases 10% every 3 years if the present population is 72600 calculate its population after 6 years and 6 years ago

Answer 1

After 6 years = 87120 people.

Before 6 years = 5808 people.

Explanation:

To calculate how many populations that are added in every 10% in 3 years:

72600 × 10/100 = 7260

After 6 years = 72600 + 7260 × 2 = 87120 people.

Before 6 years = 72600 - 7260 × 2 = 5808 people.
