There was 14.2 ℓ of water in a tank and 2.5 ℓ of water in a pail. Howard 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 Howard pour into each container?

Difference in the volume of water between the tank and the pail
= 14.2 - 2.5
= 11.7 ℓ
Since Howard 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 = 11.7
1 u = 11.7 ÷ 3 = 3.9
Volume of water that Howard poured into each container
= 1 u - 2.5
= 3.9 - 2.5
= 1.4 ℓ
Answer(s): 1.4 ℓ
