There is 227 mℓ more water in Container C than in Container B. There is 287 mℓ less water in Container B than in Container D. The total amount of water in the three containers is 1477 mℓ.
- How much more water is there in Container D than in Container C?
- How much water is there in Container B?
(a)
Volume of Container B = 1 u
Volume of Container C = 1 u + 227
Volume of Container D = 1 u + 287
Volume of more water in Container D than Container C
= 287 - 227
= 60 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 227 + 1 u + 287
= 3 u + 514
3 u + 514 = 1477
3 u = 1477 - 514
3 u = 963
1 u = 963 ÷ 3 = 321
Volume of water in Container B
= 1 u
= 321 mℓ
Answer(s): (a) 60 mℓ; (b) 321mℓ
