The population of a city is 125000. If the annual birth rate and death rate are 5.5% and 3.5% respectively, calculation the population of city after 3 year.

Explanation

Present population= `28000`
Number of years= `2`
`A=P (1+R/100)^n`
Population after 2 years
=`28000(1+5/100)^2`
=`28000(1.05)^2`
=`30870`
