There is 219 mℓ more water in Container T than in Container S. There is 331 mℓ less water in Container S than in Container U. The total amount of water in the three containers is 1495 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 + 219
Volume of Container U = 1 u + 331
Volume of more water in Container U than Container T
= 331 - 219
= 112 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 219 + 1 u + 331
= 3 u + 550
3 u + 550 = 1495
3 u = 1495 - 550
3 u = 945
1 u = 945 ÷ 3 = 315
Volume of water in Container S
= 1 u
= 315 mℓ
Answer(s): (a) 112 mℓ; (b) 315mℓ
