There was 8.4 ℓ of water in a tank and 1.4 ℓ of water in a pail. Julian then poured in an equal volume of water into each container. Now, the volume of water in the tank is 3 times in the pail. How much water did Julian pour into each container?

Difference in the volume of water between the tank and the pail
= 8.4 - 1.4
= 7 ℓ
Since Julian 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 = 7
1 u = 7 ÷ 2 = 3.5
Volume of water that Julian poured into each container
= 1 u - 1.4
= 3.5 - 1.4
= 2.1 ℓ
Answer(s): 2.1 ℓ
