There was 9.7 ℓ of water in a basin and 1.1 ℓ of water in a tank. Brandon then poured in an equal volume of water into each container. Now, the volume of water in the basin is 3 times in the tank. How much water did Brandon pour into each container?

Difference in the volume of water between the basin and the tank
= 9.7 - 1.1
= 8.6 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 = 8.6
1 u = 8.6 ÷ 2 = 4.3
Volume of water that Brandon poured into each container
= 1 u - 1.1
= 4.3 - 1.1
= 3.2 ℓ
Answer(s): 3.2 ℓ
