There is 240 mℓ more water in Container K than in Container J. There is 292 mℓ less water in Container J than in Container L. The total amount of water in the three containers is 1513 mℓ.
- How much more water is there in Container L than in Container K?
- How much water is there in Container J?
(a)
Volume of Container J = 1 u
Volume of Container K = 1 u + 240
Volume of Container L = 1 u + 292
Volume of more water in Container L than Container K
= 292 - 240
= 52 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 240 + 1 u + 292
= 3 u + 532
3 u + 532 = 1513
3 u = 1513 - 532
3 u = 981
1 u = 981 ÷ 3 = 327
Volume of water in Container J
= 1 u
= 327 mℓ
Answer(s): (a) 52 mℓ; (b) 327mℓ
