Question

A beekeeper collected 25 kg of honey from one of his hives in 2016. This was 25% more than he collected from the same hive in 2015.

In 2017 he collected 10% less honey than in 2016.
What percentage of the 2015 honey collected is the 2017 honey collected?

Answer 1

40 is the correct answer to this question

Answer 2

Let the amount collected in 2015 = X

In 2016 they collected 25% more so in 2015 they collected 1.25x

1.25x = 25

Divide both sides by 1.25:

x =25/1.25 = 20

They collected 20 kg in 2015

In 2017 they collected 25 x 0.90 = 22.5 kg

20/22.5 = 0.8888

0888 x 100 = 88.888% Round the percentage as needed:

In 2015 they collected 88.89% less than they collected in 2017.
