Question

The population of a town increased by 10%annually .If the present population is 2200 ,find the population a year ago

Answer 1

Answer:

The population 1 year ago will be 2000.

Step-by-step explanation:

Hey Mate,

Given,

Present population of town = 2200

Rate of increase in population annually = 10%

Let the population 1 year ago be x .

So,

(x + 10% of x) = 2200

(x + x/10) = 2200

11x/10 = 2200

x = 2200 × 10/11

x = 2000

So,

The population 1 year ago will be 2000.

Hope it's help you.

Thank-you
