There is 235 mℓ more water in Container F than in Container E. There is 284 mℓ less water in Container E than in Container G. The total amount of water in the three containers is 1497 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 + 235
Volume of Container G = 1 u + 284
Volume of more water in Container G than Container F
= 284 - 235
= 49 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 235 + 1 u + 284
= 3 u + 519
3 u + 519 = 1497
3 u = 1497 - 519
3 u = 978
1 u = 978 ÷ 3 = 326
Volume of water in Container E
= 1 u
= 326 mℓ
Answer(s): (a) 49 mℓ; (b) 326mℓ
