There was 15.2 ℓ of water in a tank and 1.7 ℓ of water in a pail. Vaidev 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 Vaidev pour into each container?

Difference in the volume of water between the tank and the pail
= 15.2 - 1.7
= 13.5 ℓ
Since Vaidev 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 = 13.5
1 u = 13.5 ÷ 3 = 4.5
Volume of water that Vaidev poured into each container
= 1 u - 1.7
= 4.5 - 1.7
= 2.8 ℓ
Answer(s): 2.8 ℓ
