There was 8.3 ℓ of water in a pail and 1.1 ℓ of water in a basin. Andy then poured in an equal volume of water into each container. Now, the volume of water in the pail is 4 times in the basin. How much water did Andy pour into each container?

Difference in the volume of water between the pail and the basin
= 8.3 - 1.1
= 7.2 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 = 7.2
1 u = 7.2 ÷ 3 = 2.4
Volume of water that Andy poured into each container
= 1 u - 1.1
= 2.4 - 1.1
= 1.3 ℓ
Answer(s): 1.3 ℓ
