There is 213 mℓ more water in Container Q than in Container P. There is 344 mℓ less water in Container P than in Container R. The total amount of water in the three containers is 1550 mℓ.
- How much more water is there in Container R than in Container Q?
- How much water is there in Container P?
(a)
Volume of Container P = 1 u
Volume of Container Q = 1 u + 213
Volume of Container R = 1 u + 344
Volume of more water in Container R than Container Q
= 344 - 213
= 131 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 213 + 1 u + 344
= 3 u + 557
3 u + 557 = 1550
3 u = 1550 - 557
3 u = 993
1 u = 993 ÷ 3 = 331
Volume of water in Container P
= 1 u
= 331 mℓ
Answer(s): (a) 131 mℓ; (b) 331mℓ
