There was 12 ℓ of water in a pail and 1.2 ℓ of water in a basin. Jack then poured in an equal volume of water into each container. Now, the volume of water in the pail is 5 times in the basin. How much water did Jack pour into each container?

Difference in the volume of water between the pail and the basin
= 12 - 1.2
= 10.8 ℓ
Since Jack 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 = 10.8
1 u = 10.8 ÷ 4 = 2.7
Volume of water that Jack poured into each container
= 1 u - 1.2
= 2.7 - 1.2
= 1.5 ℓ
Answer(s): 1.5 ℓ
