There was 15.2 ℓ of water in a tank and 2.8 ℓ of water in a pail. Jeremy 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 Jeremy pour into each container?

Difference in the volume of water between the tank and the pail
= 15.2 - 2.8
= 12.4 ℓ
Since Jeremy 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 = 12.4
1 u = 12.4 ÷ 4 = 3.1
Volume of water that Jeremy poured into each container
= 1 u - 2.8
= 3.1 - 2.8
= 0.3 ℓ
Answer(s): 0.3 ℓ
