There is 221 mℓ more water in Container P than in Container N. There is 279 mℓ less water in Container N than in Container Q. The total amount of water in the three containers is 1544 mℓ.
- How much more water is there in Container Q than in Container P?
- How much water is there in Container N?
(a)
Volume of Container N = 1 u
Volume of Container P = 1 u + 221
Volume of Container Q = 1 u + 279
Volume of more water in Container Q than Container P
= 279 - 221
= 58 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 221 + 1 u + 279
= 3 u + 500
3 u + 500 = 1544
3 u = 1544 - 500
3 u = 1044
1 u = 1044 ÷ 3 = 348
Volume of water in Container N
= 1 u
= 348 mℓ
Answer(s): (a) 58 mℓ; (b) 348mℓ
