	$A = P {(1 + r)}^{n}$ $at 1985 let n = 0$ $then in 1995, n = 10$ $A = 24000000, P = 20000000$ $\Rightarrow 24000000 = 20000000 {(1 + r)}^{10}$ $\Rightarrow 1.2 = {(1 + r)}^{10}$ $\log 1.2 = 10 \log (1 + r)$ $0.0079181246 = \log (1 + r)$ $\Rightarrow 1 + r = 1.02 \Rightarrow r = 0.02$ $now n = 5, P = 24000000, A = ?$ $\Rightarrow A = 24000000 {(1 + 0.02)}^{5} \approx 26000000$

	$well sir, you cannot expect the population$ $growth of a country to be 20, 000, 000 right$ $that is not logical except they are Rabbits$ $not humans .$ $I assumed the he / she meant the population$ $not population growth .$
