Difference in the volume of water between the basin and the tank
= 21.3 - 2.1
= 19.2 ℓ
Since Ken 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 = 19.2
1 u = 19.2 ÷ 4 = 4.8
Volume of water that Ken poured into each container
= 1 u - 2.1
= 4.8 - 2.1
= 2.7 ℓ
Answer(s): 2.7 ℓ
