There is 243 mℓ more water in Container J than in Container H. There is 339 mℓ less water in Container H than in Container K. The total amount of water in the three containers is 1407 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 + 243
Volume of Container K = 1 u + 339
Volume of more water in Container K than Container J
= 339 - 243
= 96 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 243 + 1 u + 339
= 3 u + 582
3 u + 582 = 1407
3 u = 1407 - 582
3 u = 825
1 u = 825 ÷ 3 = 275
Volume of water in Container H
= 1 u
= 275 mℓ
Answer(s): (a) 96 mℓ; (b) 275mℓ
