There is 247 mℓ more water in Container W than in Container V. There is 321 mℓ less water in Container V than in Container X. The total amount of water in the three containers is 1504 mℓ.
- How much more water is there in Container X than in Container W?
- How much water is there in Container V?
(a)
Volume of Container V = 1 u
Volume of Container W = 1 u + 247
Volume of Container X = 1 u + 321
Volume of more water in Container X than Container W
= 321 - 247
= 74 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 247 + 1 u + 321
= 3 u + 568
3 u + 568 = 1504
3 u = 1504 - 568
3 u = 936
1 u = 936 ÷ 3 = 312
Volume of water in Container V
= 1 u
= 312 mℓ
Answer(s): (a) 74 mℓ; (b) 312mℓ
