There is 220 mℓ more water in Container B than in Container A. There is 335 mℓ less water in Container A than in Container C. The total amount of water in the three containers is 1512 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 + 220
Volume of Container C = 1 u + 335
Volume of more water in Container C than Container B
= 335 - 220
= 115 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 220 + 1 u + 335
= 3 u + 555
3 u + 555 = 1512
3 u = 1512 - 555
3 u = 957
1 u = 957 ÷ 3 = 319
Volume of water in Container A
= 1 u
= 319 mℓ
Answer(s): (a) 115 mℓ; (b) 319mℓ
