There was 15.7 ℓ of water in a tank and 1.7 ℓ of water in a pail. Paul then poured in an equal volume of water into each container. Now, the volume of water in the tank is 5 times in the pail. How much water did Paul pour into each container?

Difference in the volume of water between the tank and the pail
= 15.7 - 1.7
= 14 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 = 14
1 u = 14 ÷ 4 = 3.5
Volume of water that Paul poured into each container
= 1 u - 1.7
= 3.5 - 1.7
= 1.8 ℓ
Answer(s): 1.8 ℓ
