There was 12.3 ℓ of water in a basin and 1.8 ℓ of water in a tank. Ian then poured in an equal volume of water into each container. Now, the volume of water in the basin is 4 times in the tank. How much water did Ian pour into each container?

Difference in the volume of water between the basin and the tank
= 12.3 - 1.8
= 10.5 ℓ
Since Ian 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 = 10.5
1 u = 10.5 ÷ 3 = 3.5
Volume of water that Ian poured into each container
= 1 u - 1.8
= 3.5 - 1.8
= 1.7 ℓ
Answer(s): 1.7 ℓ
