There is a continuous growth in population of a village at the rate of 5% per annum. If its present population is 9261, what it was 3 years ago?

Explanation

We have,
Present population of town is = 9261
Continuous growth of population is = 5%
So, let population three years ago be = x
By using the formula,
`A = P(1+R/100) ^n`
Substituting the values, we have
`9261 = x (1+5/100)(1+5/100)(1+5/100)`
`9261 = x (1.05) (1.05) (1.05)= 8000`
Hence, population is '8000'
