Mrs Paul was preparing some pear syrup concentration for her friends. The amount of pear syrup initially used was
34 of the amount of water used. To make it more diluted, she decided to add 1200 mℓ more water into the syrup drink such that
19 of the concentration was syrup. How much syrup did she use?
|
Syrup |
Water |
Before |
3x1 = 3 u |
4x1 = 4 u |
Change |
|
+ 1200 mℓ |
After |
1x3 = 3 u |
8x3 = 24 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 Paul added
= 24 u - 4 u
= 20 u
20 u = 1200
1 u = 1200 ÷ 20 = 60
Volume of syrup that Mrs Paul used
= 3 u
= 3 x 60
= 180 mℓ
Answer(s): 180 mℓ
