There was 13.7 ℓ of water in a pail and 1.4 ℓ of water in a basin. Ian then poured in an equal volume of water into each container. Now, the volume of water in the pail is 4 times in the basin. How much water did Ian pour into each container?

Difference in the volume of water between the pail and the basin
= 13.7 - 1.4
= 12.3 ℓ
Since Ian 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 = 12.3
1 u = 12.3 ÷ 3 = 4.1
Volume of water that Ian poured into each container
= 1 u - 1.4
= 4.1 - 1.4
= 2.7 ℓ
Answer(s): 2.7 ℓ
