Question

1.
33. The population of a certain town in-
creases at a certain rate per cent per annuin.
Now it is 456976. Four years ago it was
390625. What will be it 2 years hence?

456976=390625[1+r/100]^4
(676)^2=(625)2(1+r/100)4
(1+r/100)^2=676/625
Now population 2 years later
456976*(1+r/100)^2
456976*676/625=494265
