There was 10 ℓ of water in a tank and 2.2 ℓ of water in a pail. Xavier then poured in an equal volume of water into each container. Now, the volume of water in the tank is 4 times in the pail. How much water did Xavier pour into each container?

Difference in the volume of water between the tank and the pail
= 10 - 2.2
= 7.8 ℓ
Since Xavier 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 = 7.8
1 u = 7.8 ÷ 3 = 2.6
Volume of water that Xavier poured into each container
= 1 u - 2.2
= 2.6 - 2.2
= 0.4 ℓ
Answer(s): 0.4 ℓ
