There is 246 mℓ more water in Container D than in Container C. There is 313 mℓ less water in Container C than in Container E. The total amount of water in the three containers is 1537 mℓ.
- How much more water is there in Container E than in Container D?
- How much water is there in Container C?
(a)
Volume of Container C = 1 u
Volume of Container D = 1 u + 246
Volume of Container E = 1 u + 313
Volume of more water in Container E than Container D
= 313 - 246
= 67 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 246 + 1 u + 313
= 3 u + 559
3 u + 559 = 1537
3 u = 1537 - 559
3 u = 978
1 u = 978 ÷ 3 = 326
Volume of water in Container C
= 1 u
= 326 mℓ
Answer(s): (a) 67 mℓ; (b) 326mℓ
