Question

the population of the village has a constant growth of 12% p.a. If the present population of the town is 7,84,000, What was the population two years ago?​

Answer 1

Answer:

Two year ago the population was 95,086

Step-by-step explanation:

Let P be the population two years ago.

∴  P(1+1005)2=104832

     P(100105)2=104832

     P×100105×100105=104832

                  P=105×105104832×100×100

                      =95085.71

                      =95,086 (rounding off to the nearest whole number)

∴ Two years ago the population was 95,086.
