Question

Population of a village decreases at the rate of 12% per annum. If its population 2 years ago was 62500, find its present population.

Answer 1

Its present population is 48400

Step-by-step explanation:

Population 2 years ago = 62500

We are given that Population of a village decreases at the rate of 12% per annum.

So, Population after 1 year = $62500-12\%(62500)=62500-0.12(62500)=55000$

Population after 2 year =$55000-0.12(55000)=48400$

Hence its present population is 48400
