Question
The population of a town was 160000 three years ago. If it had increased by 3%, 2.5% and 5% in last three years, its present population is
Solution
To find the present population, we need to increase the population of each year by the given percentage.
-
Increase in the first year = 160000 * 3/100 = 4800. So, the population after the first year = 160000 + 4800 = 164800.
-
Increase in the second year = 164800 * 2.5/100 = 4120. So, the population after the second year = 164800 + 4120 = 168920.
-
Increase in the third year = 168920 * 5/100 = 8446. So, the population after the third year (which is the present population) = 168920 + 8446 = 177366.
So, the present population of the town is 177366.
