There is 247 mℓ more water in Container B than in Container A. There is 278 mℓ less water in Container A than in Container C. The total amount of water in the three containers is 1422 mℓ.
- How much more water is there in Container C than in Container B?
- How much water is there in Container A?
(a)
Volume of Container A = 1 u
Volume of Container B = 1 u + 247
Volume of Container C = 1 u + 278
Volume of more water in Container C than Container B
= 278 - 247
= 31 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 247 + 1 u + 278
= 3 u + 525
3 u + 525 = 1422
3 u = 1422 - 525
3 u = 897
1 u = 897 ÷ 3 = 299
Volume of water in Container A
= 1 u
= 299 mℓ
Answer(s): (a) 31 mℓ; (b) 299mℓ
