There is 226 mℓ more water in Container F than in Container E. There is 312 mℓ less water in Container E than in Container G. The total amount of water in the three containers is 1492 mℓ.
- How much more water is there in Container G than in Container F?
- How much water is there in Container E?
(a)
Volume of Container E = 1 u
Volume of Container F = 1 u + 226
Volume of Container G = 1 u + 312
Volume of more water in Container G than Container F
= 312 - 226
= 86 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 226 + 1 u + 312
= 3 u + 538
3 u + 538 = 1492
3 u = 1492 - 538
3 u = 954
1 u = 954 ÷ 3 = 318
Volume of water in Container E
= 1 u
= 318 mℓ
Answer(s): (a) 86 mℓ; (b) 318mℓ
