There was 9.7 ℓ of water in a pail and 1.3 ℓ of water in a basin. Mark then poured in an equal volume of water into each container. Now, the volume of water in the pail is 3 times in the basin. How much water did Mark pour into each container?

Difference in the volume of water between the pail and the basin
= 9.7 - 1.3
= 8.4 ℓ
Since Mark 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 = 8.4
1 u = 8.4 ÷ 2 = 4.2
Volume of water that Mark poured into each container
= 1 u - 1.3
= 4.2 - 1.3
= 2.9 ℓ
Answer(s): 2.9 ℓ
