There was 8.4 ℓ of water in a pail and 1.8 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 3 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
= 8.4 - 1.8
= 6.6 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.
2 u = 6.6
1 u = 6.6 ÷ 2 = 3.3
Volume of water that Paul poured into each container
= 1 u - 1.8
= 3.3 - 1.8
= 1.5 ℓ
Answer(s): 1.5 ℓ
