Question

The population of a town was 25,000 at the first year of a census.

(a) If the population of the town increased to 30,000 at the second year, by what percent did the population increase?


(b) If the population decreased from 30,000 to 27,000 at the third year, by what percent did the population decrease?

Answer 1

Explanation:

a) 30,000-25,000= 5000

(5000/25,000) x 100= 20%

b) 30,000-27,000= 3000

(3000/30,000) x 100= 10%
