There was 9 ℓ of water in a pail and 2.4 ℓ of water in a basin. Lee 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 Lee pour into each container?

Difference in the volume of water between the pail and the basin
= 9 - 2.4
= 6.6 ℓ
Since Lee 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 = 6.6
1 u = 6.6 ÷ 2 = 3.3
Volume of water that Lee poured into each container
= 1 u - 2.4
= 3.3 - 2.4
= 0.9 ℓ
Answer(s): 0.9 ℓ
