Question

In 2010, the population of a city was 101,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 3%. How much did the population grow from 2010 to 2015, to the nearest 100 people?

Answer 1

Answer: 8100 people

Explanation:

2010 -> 101000 people

2015 -> Grew by 8%

100% represents 101000 people

108% represents (108/100 x 101000) people

108% represents 109080 people

Difference in the number of people = (109080 - 101000) people

= 8080 people

= 8100 people (nearest hundred people)
