There was 20.7 ℓ of water in a basin and 1.9 ℓ of water in a tank. Billy 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 Billy pour into each container?

Difference in the volume of water between the basin and the tank
= 20.7 - 1.9
= 18.8 ℓ
Since Billy 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 = 18.8
1 u = 18.8 ÷ 4 = 4.7
Volume of water that Billy poured into each container
= 1 u - 1.9
= 4.7 - 1.9
= 2.8 ℓ
Answer(s): 2.8 ℓ
