Question

The population of a town increases at a rate of 40 per thousand. Its population after 2 years will be 6084 find its present population

Answer 1

Dear Student,

◆ Answer -

Present population = 5625

● Explanation -

Let x be present population of the town.

Population after 2 years is given by -

P' = P (1 + r)^t

6084 = P (1 + 40/1000)^2

6084 = P (1 + 40/1000)^2

6084 = P (1 + 1/25)^2

6084 = P × (26/25)^2

P = 6084 × 625 / 676

P = 5625

Hence, present population of the town is 5625.
