Question

The present population of a town is 176400. If the rate of growth in its population is 5%per
annum, find : (i) its population 2 years hence, (i) its population one year ago​

Answer 1

V = ?

Vo = 176400

Rate = 5% p.a

Time = 2 years

• Formula = V = Vo(1+r/100)^n

( i )  the population in two years =

     V = 176400(1+5/100)²

     V = 176400*21/20*21/20

     V = 441*21*21

     V = 194481
