There was 8.8 ℓ of water in a pail and 1.3 ℓ of water in a basin. Japheth 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 Japheth pour into each container?

Difference in the volume of water between the pail and the basin
= 8.8 - 1.3
= 7.5 ℓ
Since Japheth 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 = 7.5
1 u = 7.5 ÷ 3 = 2.5
Volume of water that Japheth poured into each container
= 1 u - 1.3
= 2.5 - 1.3
= 1.2 ℓ
Answer(s): 1.2 ℓ
