There was 15.2 ℓ of water in a bucket and 2.9 ℓ of water in a pail. Rael then poured in an equal volume of water into each container. Now, the volume of water in the bucket is 4 times in the pail. How much water did Rael pour into each container?

Difference in the volume of water between the bucket and the pail
= 15.2 - 2.9
= 12.3 ℓ
Since Rael 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.
3 u = 12.3
1 u = 12.3 ÷ 3 = 4.1
Volume of water that Rael poured into each container
= 1 u - 2.9
= 4.1 - 2.9
= 1.2 ℓ
Answer(s): 1.2 ℓ
