There was 10.5 ℓ of water in a tank and 2.9 ℓ of water in a pail. Sean then poured in an equal volume of water into each container. Now, the volume of water in the tank is 3 times in the pail. How much water did Sean pour into each container?

Difference in the volume of water between the tank and the pail
= 10.5 - 2.9
= 7.6 ℓ
Since Sean 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.
2 u = 7.6
1 u = 7.6 ÷ 2 = 3.8
Volume of water that Sean poured into each container
= 1 u - 2.9
= 3.8 - 2.9
= 0.9 ℓ
Answer(s): 0.9 ℓ
