Question

the population of city increases 20% annually. if the present population is 36000. find population of city after 2 years

Answer 1

Annually it increases 20%

So in the first year population will become

36000+20/100*36000

=36000+7200

=43200

Next year again add 20% to the population.

=43200+20/100*43200

=43200+8640

=51840

Thats the population after 2 years:51840

Thanks.
