The population of a city was 20000 in the year 2007.It increased at the rate of 5% p.a.Find the population at the end of the year 2010​

Answer 1

So the Population in 2007 = 20,000 It increases at the rate of 5% p.a

So, 5% of 20,000 = (5/100) * 20,000 =

1000

Which Means every year 1000 people are increasing

Population in 2010 = 20,000 + (3*1000) = 23,000
