There was 12.1 ℓ of water in a basin and 2.5 ℓ of water in a tank. Sean then poured in an equal volume of water into each container. Now, the volume of water in the basin is 3 times in the tank. How much water did Sean pour into each container?

Difference in the volume of water between the basin and the tank
= 12.1 - 2.5
= 9.6 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 = 9.6
1 u = 9.6 ÷ 2 = 4.8
Volume of water that Sean poured into each container
= 1 u - 2.5
= 4.8 - 2.5
= 2.3 ℓ
Answer(s): 2.3 ℓ
