There was 5.8 ℓ of water in a pail and 1.6 ℓ of water in a basin. Pierre then poured in an equal volume of water into each container. Now, the volume of water in the pail is 3 times in the basin. How much water did Pierre pour into each container?

Difference in the volume of water between the pail and the basin
= 5.8 - 1.6
= 4.2 ℓ
Since Pierre 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.
2 u = 4.2
1 u = 4.2 ÷ 2 = 2.1
Volume of water that Pierre poured into each container
= 1 u - 1.6
= 2.1 - 1.6
= 0.5 ℓ
Answer(s): 0.5 ℓ
