Question

The population of a town increases by 20 %every year. If its present population is 216000. Find it's population after 2 years and before 2 years?????

Answer 1

Step-by-step explanation:

If population increases by 20% each year

let the present population is P(0) = 216000.

P(1) = Population after 1 year = P(0) X (100+20)/(100) = 1.2 X P(0)

Now, P(2) = 1.2 X 1.2 X P(0) = 311040.

Population after 2 years.

P(-1) = Population 1 year ago = P / 1.2

P(-2) = P/(1.2 X 1.2) = 150000. Population 2 years ago.
