The population of Town X in 2018 and 2019 together is approximately what percentage of the population of Town Y in 2021 and 2022 together?

A86.6 ✓ Correct

B89.6

C81.6

D84.5

Correct answer: (A) 86.6

Explanation

The figure is about 86.6%, so the answer is 86.6.

Town X in 2018 and 2019 is 50 plus 49 plus 52 plus 49, which is 200.

Town Y in 2021 and 2022 is 58 plus 56 plus 62 plus 55, which is 231.

The required percentage is 200 divided by 231 times 100.

This works out to about 86.58%, which rounds to 86.6%.
