Question

A village has a population of 2000 and is currently growing at a rate of 3.7% per annum. If growth stays constant, what will the population be in 2 years’ time?

Answer 1

A village has population of 2000 and is currently growing at a rate of 3.7℅ per annum. Growth is given to be constant. We have to calculate what will be the population in 2 year's time.

First we will calculate population in next 1 year. Growth rate is 3.7℅ so we will calculate 3.7℅ of 2000 as

2000×(3.7/100) =74 so the population in next one year would be 2000+74= 2074.

Growth rate is constant so population in next two year would increase by 3.7℅ of 2074 which is

2074×(3.7/100) = 76.7380

So population in two year's time is 2074+76.7380=2150.738

So the population in 2 year's time would be 2151 (approximately).

This answers your question. If you understood, please rate positively.
