There is 214 mℓ more water in Container Y than in Container X. There is 306 mℓ less water in Container X than in Container Z. The total amount of water in the three containers is 1519 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 + 214
Volume of Container Z = 1 u + 306
Volume of more water in Container Z than Container Y
= 306 - 214
= 92 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 214 + 1 u + 306
= 3 u + 520
3 u + 520 = 1519
3 u = 1519 - 520
3 u = 999
1 u = 999 ÷ 3 = 333
Volume of water in Container X
= 1 u
= 333 mℓ
Answer(s): (a) 92 mℓ; (b) 333mℓ
