There was 16.5 ℓ of water in a bucket and 2.1 ℓ of water in a pail. Justin then poured in an equal volume of water into each container. Now, the volume of water in the bucket is 5 times in the pail. How much water did Justin pour into each container?

Difference in the volume of water between the bucket and the pail
= 16.5 - 2.1
= 14.4 ℓ
Since Justin poured in an equal volume of water into each container, the difference in the volume of water at first and in the end remains the same.
4 u = 14.4
1 u = 14.4 ÷ 4 = 3.6
Volume of water that Justin poured into each container
= 1 u - 2.1
= 3.6 - 2.1
= 1.5 ℓ
Answer(s): 1.5 ℓ
