Rate of increase in population of a state is 2% in a year. The present population is 80000000; let us calculate the population of the state after 3 years.

We know that population after n year


Where p = present population, r% = rate of increase in population in one year and n = number of years.


Given p = 80000000, r% = 2% and n = 3 years
