Question

The population of a town increases by 10% annually. If the present population is 60000, what will be its population after 2 years?

Answer 1

Given details are,

Present population of town is = 60000

Annually population increases by = 10%

So, Population after 2 years = present population × [(100 + increased %)/100] years

= 60000 × (100+10)/100 × (100+10)/100

= 60000 × 110/100 × 110/100

= 60000 × 11/10 × 11/10

= 72600

∴ After 2 years population will be 72600.
