Answer 2

The population two years ago is 72541.

Given: The population of a village has a constant growth of 6.25% every year and the present population is 82536.

To Find: The population two years ago.

Solution:

The present population is = 82536

The rate of decrease in population per year = 6.25 %

The population 1 year ago = 82536 - (( 6.25 × 82536) / 100 )

                                            = 77377.5

Again population  2 years ago = 77377.5 - (( 6.25 × 77377.5) / 100 )

                                                   = 72541

Hence, the population two years ago is 72541.
