At present the population of village of Pahalanpur is 10000; if population is being increased at the rate of 3% every year, let us write by calculating its population after 2 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 = 10000, r% = 3% and n = 2 years
