Question

A swimming pool had 2.5 million liters of water in it. Some water evaporated, and then the pool only had 2 million liters of water in it.

What percent of the water evaporated?

Answer 1

25 % of the water had evaporated.

Answer 2

20%

Since the total amount of water is 2.5 million

And 2 million evaporated,

To determine the amount left,it will be total amount- evaporated

2.5-2=0.5

To determine the% of evaporated water

It will be evaporated/total amount ×100

0.5/2.5 × 100

50/2.5

20%

So the percentage of the evaporated water is 20%
