There is 234 mℓ more water in Container J than in Container H. There is 317 mℓ less water in Container H than in Container K. The total amount of water in the three containers is 1490 mℓ.
- How much more water is there in Container K than in Container J?
- How much water is there in Container H?
(a)
Volume of Container H = 1 u
Volume of Container J = 1 u + 234
Volume of Container K = 1 u + 317
Volume of more water in Container K than Container J
= 317 - 234
= 83 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 234 + 1 u + 317
= 3 u + 551
3 u + 551 = 1490
3 u = 1490 - 551
3 u = 939
1 u = 939 ÷ 3 = 313
Volume of water in Container H
= 1 u
= 313 mℓ
Answer(s): (a) 83 mℓ; (b) 313mℓ
