The population of village is 1,00,000. The rate of increase is 10% per annum. Find the population at the start of the third year?

100000 == 10%↑(1st year) ==> 110000 == 10%↑(2nd year) ==> 121000 Population at starting of 3rd year = 121000 [By using net percentage change method, we have saved our self from cumber some formulas on population which is based on compound interest].
