Answer 2

Given - Original population and increase percentage

Find - Present population

Solution - To find the present population, first we will find 5% of original population which has increased. Addition will be followed to get the present population.

Increase in population = 5%*20320

Increase in population = 5*20320/100

Performing multiplication and division

Increase in population = 1016

Present population = 20320 + 1016

Performing addition

Present population = 21,336

Hence, the present population of the town is 21,336.
