Question

The population of a town increased by 15% in 2016, and decreased by 5% in 2017. If the population of the town was 60,000 in the beginning of 2016, then what was it at the end of 2017?

Answer 1

The population of the town at the end of 2017 was 65,550.

Explanation:

The population of the town was 60,000 in the beginning of 2016.

In 2016, the total population is increased by 15%.

`60,000*(15)/(100)=9000`

Therefore the population is increased by 9000 and the population of the town at the end of 2016 was

`60,000+9000=69,000`

In 2017, the total population is decreased by 5%.

`69,000*(5)/(100)=3450`

Therefore the population is decreased by 3450 and the population of the town at the end of 2017 was

`69,000-3450=65,500`

Therefore the population of the town at the end of 2017 was 65,550.
