There was 12 ℓ of water in a tank and 2.7 ℓ of water in a pail. Harry then poured in an equal volume of water into each container. Now, the volume of water in the tank is 4 times in the pail. How much water did Harry pour into each container?

Difference in the volume of water between the tank and the pail
= 12 - 2.7
= 9.3 ℓ
Since Harry 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 = 9.3
1 u = 9.3 ÷ 3 = 3.1
Volume of water that Harry poured into each container
= 1 u - 2.7
= 3.1 - 2.7
= 0.4 ℓ
Answer(s): 0.4 ℓ
