There was 10.1 ℓ of water in a pail and 1.4 ℓ of water in a basin. John 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 John pour into each container?

Difference in the volume of water between the pail and the basin
= 10.1 - 1.4
= 8.7 ℓ
Since John 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 = 8.7
1 u = 8.7 ÷ 3 = 2.9
Volume of water that John poured into each container
= 1 u - 1.4
= 2.9 - 1.4
= 1.5 ℓ
Answer(s): 1.5 ℓ
