There was 15.8 ℓ of water in a pail and 1.1 ℓ of water in a basin. David 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 David pour into each container?

Difference in the volume of water between the pail and the basin
= 15.8 - 1.1
= 14.7 ℓ
Since David 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 = 14.7
1 u = 14.7 ÷ 3 = 4.9
Volume of water that David poured into each container
= 1 u - 1.1
= 4.9 - 1.1
= 3.8 ℓ
Answer(s): 3.8 ℓ
