There is 245 mℓ more water in Container N than in Container M. There is 281 mℓ less water in Container M than in Container P. The total amount of water in the three containers is 1576 mℓ.
- How much more water is there in Container P than in Container N?
- How much water is there in Container M?
(a)
Volume of Container M = 1 u
Volume of Container N = 1 u + 245
Volume of Container P = 1 u + 281
Volume of more water in Container P than Container N
= 281 - 245
= 36 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 245 + 1 u + 281
= 3 u + 526
3 u + 526 = 1576
3 u = 1576 - 526
3 u = 1050
1 u = 1050 ÷ 3 = 350
Volume of water in Container M
= 1 u
= 350 mℓ
Answer(s): (a) 36 mℓ; (b) 350mℓ
