Mrs Reggie was preparing some starfruit syrup concentration for her friends. The amount of starfruit syrup initially used was
38 of the amount of water used. To make it more diluted, she decided to add 1500 mℓ more water into the syrup drink such that
15 of the concentration was syrup. How much syrup did she use?
|
Syrup |
Water |
Before |
3x1 = 3 u |
8x1 = 8 u |
Change |
|
+ 1500 mℓ |
After |
1x3 = 3 u |
4x3 = 12 u |
The volume of syrup at first and in the end remains unchanged. Make the volume of syrup the same. LCM of 1 and 3 is 3.
Volume of water that Mrs Reggie added
= 12 u - 8 u
= 4 u
4 u = 1500
1 u = 1500 ÷ 4 = 375
Volume of syrup that Mrs Reggie used
= 3 u
= 3 x 375
= 1125 mℓ
Answer(s): 1125 mℓ
