There was 9.9 ℓ of water in a tank and 1.8 ℓ of water in a pail. Owen then poured in an equal volume of water into each container. Now, the volume of water in the tank is 4 times in the pail. How much water did Owen pour into each container?

Difference in the volume of water between the tank and the pail
= 9.9 - 1.8
= 8.1 ℓ
Since Owen 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 = 8.1
1 u = 8.1 ÷ 3 = 2.7
Volume of water that Owen poured into each container
= 1 u - 1.8
= 2.7 - 1.8
= 0.9 ℓ
Answer(s): 0.9 ℓ
