The population of a town is 705600. If it increases at the rate of 5% per annum, then what will be its population 2yr hence?

Given that,
P = 705600, R = 5% and n = 2
According to the formula,
Population after n yr = p(1 + R/100)ⁿ
∴ Population after 2 yr.
= 705600 x (1+ 5/100)²
= 705600 x (105/100)²
= 705600 x (21/20 x 21/20) = 777924
