There is 249 mℓ more water in Container F than in Container E. There is 292 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 + 249
Volume of Container G = 1 u + 292
Volume of more water in Container G than Container F
= 292 - 249
= 43 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 249 + 1 u + 292
= 3 u + 541
3 u + 541 = 1492
3 u = 1492 - 541
3 u = 951
1 u = 951 ÷ 3 = 317
Volume of water in Container E
= 1 u
= 317 mℓ
Answer(s): (a) 43 mℓ; (b) 317mℓ
