There was 21.3 ℓ of water in a basin and 1.7 ℓ of water in a tank. Eric then poured in an equal volume of water into each container. Now, the volume of water in the basin is 5 times in the tank. How much water did Eric pour into each container?

Difference in the volume of water between the basin and the tank
= 21.3 - 1.7
= 19.6 ℓ
Since Eric 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.
4 u = 19.6
1 u = 19.6 ÷ 4 = 4.9
Volume of water that Eric poured into each container
= 1 u - 1.7
= 4.9 - 1.7
= 3.2 ℓ
Answer(s): 3.2 ℓ
