There is 235 mℓ more water in Container X than in Container W. There is 307 mℓ less water in Container W than in Container Y. The total amount of water in the three containers is 1598 mℓ.
- How much more water is there in Container Y than in Container X?
- How much water is there in Container W?
(a)
Volume of Container W = 1 u
Volume of Container X = 1 u + 235
Volume of Container Y = 1 u + 307
Volume of more water in Container Y than Container X
= 307 - 235
= 72 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 235 + 1 u + 307
= 3 u + 542
3 u + 542 = 1598
3 u = 1598 - 542
3 u = 1056
1 u = 1056 ÷ 3 = 352
Volume of water in Container W
= 1 u
= 352 mℓ
Answer(s): (a) 72 mℓ; (b) 352mℓ
