There is 236 mℓ more water in Container B than in Container A. There is 303 mℓ less water in Container A than in Container C. The total amount of water in the three containers is 1457 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 + 236
Volume of Container C = 1 u + 303
Volume of more water in Container C than Container B
= 303 - 236
= 67 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 236 + 1 u + 303
= 3 u + 539
3 u + 539 = 1457
3 u = 1457 - 539
3 u = 918
1 u = 918 ÷ 3 = 306
Volume of water in Container A
= 1 u
= 306 mℓ
Answer(s): (a) 67 mℓ; (b) 306mℓ
