The amount of honeydew syrup to the amount of water in Cup A is in the ratio 3 : 5. The amount of honeydew syrup to the amount of water in Cup B is in the ratio 1 : 3. There is an equal amount of honeydew syrup in both cups. Cup B contains 80 mℓ more water than Cup A. What is the amount of honeydew syrup in Cup A? Leave the answer in mℓ.

The amount of syrup in Cup A and Cup B is the same. Make the amount of syrup the same. LCM of 3 and 1 is 3.
Amount of more water in Cup B than Cup A
= 9 u - 5 u
= 4 u
4 u = 80
1 u = 80 ÷ 4 = 20
Amount of honeydew syrup in Cup A
= 3 u
= 3 x 20
= 60 mℓ
Answer(s): 60 mℓ
