There was 15.3 ℓ of water in a basin and 2.1 ℓ of water in a tank. Andy then poured in an equal volume of water into each container. Now, the volume of water in the basin is 4 times in the tank. How much water did Andy pour into each container?

Difference in the volume of water between the basin and the tank
= 15.3 - 2.1
= 13.2 ℓ
Since Andy 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 = 13.2
1 u = 13.2 ÷ 3 = 4.4
Volume of water that Andy poured into each container
= 1 u - 2.1
= 4.4 - 2.1
= 2.3 ℓ
Answer(s): 2.3 ℓ
