There was 17.1 ℓ of water in a pail and 1.5 ℓ of water in a basin. Paul then poured in an equal volume of water into each container. Now, the volume of water in the pail is 5 times in the basin. How much water did Paul pour into each container?

Difference in the volume of water between the pail and the basin
= 17.1 - 1.5
= 15.6 ℓ
Since Paul 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.
4 u = 15.6
1 u = 15.6 ÷ 4 = 3.9
Volume of water that Paul poured into each container
= 1 u - 1.5
= 3.9 - 1.5
= 2.4 ℓ
Answer(s): 2.4 ℓ
