Mrs Flynn was preparing some lemon syrup concentration for her friends. The amount of lemon syrup initially used was
37 of the amount of water used. To make it more diluted, she decided to add 1000 mℓ more water into the syrup drink such that
14 of the concentration was syrup. How much syrup did she use?
|
Syrup |
Water |
Before |
3x1 = 3 u |
7x1 = 7 u |
Change |
|
+ 1000 mℓ |
After |
1x3 = 3 u |
3x3 = 9 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 Flynn added
= 9 u - 7 u
= 2 u
2 u = 1000
1 u = 1000 ÷ 2 = 500
Volume of syrup that Mrs Flynn used
= 3 u
= 3 x 500
= 1500 mℓ
Answer(s): 1500 mℓ
