The population of a town increase by 20% every year. If the present population of the town is 96000, then what was the population of the town last year? Correct Answer 80000

Population of a town increase by 20% every year

Let the population of the town last year was A

∴ 96000 = A × (100 + 20)/100

96000 = (120/100) A

A = (96000 × 100)/120

A = 80000
