There was 7.7 ℓ of water in a pail and 1.5 ℓ of water in a basin. Brandon 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 Brandon pour into each container?

Difference in the volume of water between the pail and the basin
= 7.7 - 1.5
= 6.2 ℓ
Since Brandon 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 = 6.2
1 u = 6.2 ÷ 2 = 3.1
Volume of water that Brandon poured into each container
= 1 u - 1.5
= 3.1 - 1.5
= 1.6 ℓ
Answer(s): 1.6 ℓ
