There is 202 mℓ more water in Container B than in Container A. There is 308 mℓ less water in Container A than in Container C. The total amount of water in the three containers is 1581 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 + 202
Volume of Container C = 1 u + 308
Volume of more water in Container C than Container B
= 308 - 202
= 106 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 202 + 1 u + 308
= 3 u + 510
3 u + 510 = 1581
3 u = 1581 - 510
3 u = 1071
1 u = 1071 ÷ 3 = 357
Volume of water in Container A
= 1 u
= 357 mℓ
Answer(s): (a) 106 mℓ; (b) 357mℓ
