There was 18.7 ℓ of water in a pail and 1.9 ℓ of water in a basin. Julian then poured in an equal volume of water into each container. Now, the volume of water in the pail is 5 times in the basin. How much water did Julian pour into each container?

Difference in the volume of water between the pail and the basin
= 18.7 - 1.9
= 16.8 ℓ
Since Julian 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.
4 u = 16.8
1 u = 16.8 ÷ 4 = 4.2
Volume of water that Julian poured into each container
= 1 u - 1.9
= 4.2 - 1.9
= 2.3 ℓ
Answer(s): 2.3 ℓ
