There is 226 mℓ more water in Container Q than in Container P. There is 337 mℓ less water in Container P than in Container R. The total amount of water in the three containers is 1448 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 + 226
Volume of Container R = 1 u + 337
Volume of more water in Container R than Container Q
= 337 - 226
= 111 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 226 + 1 u + 337
= 3 u + 563
3 u + 563 = 1448
3 u = 1448 - 563
3 u = 885
1 u = 885 ÷ 3 = 295
Volume of water in Container P
= 1 u
= 295 mℓ
Answer(s): (a) 111 mℓ; (b) 295mℓ
