There is 220 mℓ more water in Container R than in Container Q. There is 328 mℓ less water in Container Q than in Container S. The total amount of water in the three containers is 1529 mℓ.
- How much more water is there in Container S than in Container R?
- How much water is there in Container Q?
(a)
Volume of Container Q = 1 u
Volume of Container R = 1 u + 220
Volume of Container S = 1 u + 328
Volume of more water in Container S than Container R
= 328 - 220
= 108 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 220 + 1 u + 328
= 3 u + 548
3 u + 548 = 1529
3 u = 1529 - 548
3 u = 981
1 u = 981 ÷ 3 = 327
Volume of water in Container Q
= 1 u
= 327 mℓ
Answer(s): (a) 108 mℓ; (b) 327mℓ
