Question

Population increases R% every year and after n years the population becomes P. What was/were the population before n years?

Answer 1

`P_0 = P / (1 +0.01*R)^n`

Explanation:

Let's same `P_0` is the Initial (Starting) Population.
To Find Resulting P after n years with a growth rate of R%:
`P = P_0(1 + 0.01*R)^n`

To find what was the population before n years, we need to solve for `P_0`:

`P_0 = P / (1 +0.01*R)^n`
