There was 11.9 ℓ of water in a tank and 1.5 ℓ of water in a pail. Archie 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 Archie pour into each container?

Difference in the volume of water between the tank and the pail
= 11.9 - 1.5
= 10.4 ℓ
Since Archie 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 = 10.4
1 u = 10.4 ÷ 4 = 2.6
Volume of water that Archie poured into each container
= 1 u - 1.5
= 2.6 - 1.5
= 1.1 ℓ
Answer(s): 1.1 ℓ
