Question

The present population of a town is 176400. If it increases at the rate of 5% p. a. ,what will be its population after 2 years?

Answer 1

Present population = 176400 , inc rate p.a = 5% ( 5% of current pop.)

First year,5% of 176400= 5/100*576400=28820

So,inc pop. = old pop + inc = 176400+ 28820 = 205220

Second year, 5 % of 205220 = 5/100*205220= 10261

So,inc pop = old pop + inc = 205220+10261=215481

Hence,pop. after 2 years = 215481 (ans)

Answer 2

Present population = 176400 , inc rate p.a = 5% ( 5% of current pop.)

First year,5% of 176400= 5/100*576400=28820

So,inc pop. = old pop + inc = 176400+ 28820 = 205220

Second year, 5 % of 205220 = 5/100*205220= 10261

So,inc pop = old pop + inc = 205220+10261=215481

Hence,pop. after 2 years = 215481 (ans)
