There is 238 mℓ more water in Container T than in Container S. There is 313 mℓ less water in Container S than in Container U. The total amount of water in the three containers is 1439 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 + 238
Volume of Container U = 1 u + 313
Volume of more water in Container U than Container T
= 313 - 238
= 75 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 238 + 1 u + 313
= 3 u + 551
3 u + 551 = 1439
3 u = 1439 - 551
3 u = 888
1 u = 888 ÷ 3 = 296
Volume of water in Container S
= 1 u
= 296 mℓ
Answer(s): (a) 75 mℓ; (b) 296mℓ
