Question

the population of a city was 30000 at the beginning of the year 1999 it increased at the rate of 5%p.a. calculate the population at the end of the year 2001?

Answer 1

This sum is a reference for your question please see it and try to do yours

A = P(1+ R/100)N

Initial population of the city (P) = 20,000

Rate of increase (R) = 5% pa

N (number of years) =3

Population of the city after 3 years = A

A = 20000(1+5/100)³

= 20000(105/100)³

= (20000*105*105*105)/(100*100*100)

A = 23152.5

So, population of city after 3 years = 23152.5
