Question

The population of a town increases at the rate of 7% every year. If the present population is 90,000, what will it be after two years ?

Answer 1

Present population of town = 90000
Population increase every year = 7%
population after 1 year = 7% of 90000
=> 7/100×90000
=> 7×900
=> 6300
New number of population = 90000+6300
=> 96300
Population after 2 years = 7% of 96300
=> 7/100×96300
=> 7×963
=> 6741
new number of population = 96300+6741
=> 103041
Hence the required population after 2 years is 1,03,041
