There was 10.9 ℓ of water in a basin and 2.1 ℓ of water in a tank. John 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 John pour into each container?

Difference in the volume of water between the basin and the tank
= 10.9 - 2.1
= 8.8 ℓ
Since John 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 = 8.8
1 u = 8.8 ÷ 2 = 4.4
Volume of water that John poured into each container
= 1 u - 2.1
= 4.4 - 2.1
= 2.3 ℓ
Answer(s): 2.3 ℓ
