There was 11.5 ℓ of water in a bucket and 2.2 ℓ of water in a pail. Archie 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 Archie pour into each container?

Difference in the volume of water between the bucket and the pail
= 11.5 - 2.2
= 9.3 ℓ
Since Archie 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 = 9.3
1 u = 9.3 ÷ 3 = 3.1
Volume of water that Archie poured into each container
= 1 u - 2.2
= 3.1 - 2.2
= 0.9 ℓ
Answer(s): 0.9 ℓ
