There was 12.7 ℓ of water in a pail and 2.2 ℓ of water in a basin. Ahmad then poured in an equal volume of water into each container. Now, the volume of water in the pail is 4 times in the basin. How much water did Ahmad pour into each container?

Difference in the volume of water between the pail and the basin
= 12.7 - 2.2
= 10.5 ℓ
Since Ahmad 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 = 10.5
1 u = 10.5 ÷ 3 = 3.5
Volume of water that Ahmad poured into each container
= 1 u - 2.2
= 3.5 - 2.2
= 1.3 ℓ
Answer(s): 1.3 ℓ
