There is 205 mℓ more water in Container Y than in Container X. There is 339 mℓ less water in Container X than in Container Z. The total amount of water in the three containers is 1588 mℓ.
- How much more water is there in Container Z than in Container Y?
- How much water is there in Container X?
(a)
Volume of Container X = 1 u
Volume of Container Y = 1 u + 205
Volume of Container Z = 1 u + 339
Volume of more water in Container Z than Container Y
= 339 - 205
= 134 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 205 + 1 u + 339
= 3 u + 544
3 u + 544 = 1588
3 u = 1588 - 544
3 u = 1044
1 u = 1044 ÷ 3 = 348
Volume of water in Container X
= 1 u
= 348 mℓ
Answer(s): (a) 134 mℓ; (b) 348mℓ
