There is 207 mℓ more water in Container J than in Container H. There is 297 mℓ less water in Container H than in Container K. The total amount of water in the three containers is 1542 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 + 207
Volume of Container K = 1 u + 297
Volume of more water in Container K than Container J
= 297 - 207
= 90 mℓ
(b)
Total volume in the 3 containers
= 1 u + 1 u + 207 + 1 u + 297
= 3 u + 504
3 u + 504 = 1542
3 u = 1542 - 504
3 u = 1038
1 u = 1038 ÷ 3 = 346
Volume of water in Container H
= 1 u
= 346 mℓ
Answer(s): (a) 90 mℓ; (b) 346mℓ
