There was 10.3 ℓ of water in a tank and 2.9 ℓ of water in a pail. Luis 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 Luis pour into each container?

Difference in the volume of water between the tank and the pail
= 10.3 - 2.9
= 7.4 ℓ
Since Luis 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 = 7.4
1 u = 7.4 ÷ 2 = 3.7
Volume of water that Luis poured into each container
= 1 u - 2.9
= 3.7 - 2.9
= 0.8 ℓ
Answer(s): 0.8 ℓ
