There was 12.5 ℓ of water in a basin and 2.7 ℓ of water in a tank. Ivan then poured in an equal volume of water into each container. Now, the volume of water in the basin is 3 times in the tank. How much water did Ivan pour into each container?

Difference in the volume of water between the basin and the tank
= 12.5 - 2.7
= 9.8 ℓ
Since Ivan 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 = 9.8
1 u = 9.8 ÷ 2 = 4.9
Volume of water that Ivan poured into each container
= 1 u - 2.7
= 4.9 - 2.7
= 2.2 ℓ
Answer(s): 2.2 ℓ
