There is 242 mℓ more water in Container T than in Container S. There is 342 mℓ less water in Container S than in Container U. The total amount of water in the three containers is 1556 mℓ.
- How much more water is there in Container U than in Container T?
- How much water is there in Container S?
(a)
Volume of Container S = 1 u
Volume of Container T = 1 u + 242
Volume of Container U = 1 u + 342
Volume of more water in Container U than Container T
= 342 - 242
= 100 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 242 + 1 u + 342
= 3 u + 584
3 u + 584 = 1556
3 u = 1556 - 584
3 u = 972
1 u = 972 ÷ 3 = 324
Volume of water in Container S
= 1 u
= 324 mℓ
Answer(s): (a) 100 mℓ; (b) 324mℓ
