Question

The population of a town increases at the rate of 50 per thousand. if the estimated population after 2years will be 22050,find the present population of the town.​

Answer 1

Answer:

20000

Step-by-step explanation:

Population increase year-on-year = 50 per 1000 = 5%

Population at year 2 = 22050

Population at year 1 = 22050 / (1 + 5%) = 22050/1.05 = 21000

Population at present = 21000 / (1 + 5%) = 21000/1.05 = 20000
