Mrs Reggie was preparing some chikoo syrup concentration for her friends. The amount of chikoo syrup initially used was
34 of the amount of water used. To make it more diluted, she decided to add 900 mℓ more water into the syrup drink such that
13 of the concentration was syrup. How much syrup did she use?
|
Syrup |
Water |
Before |
3x1 = 3 u |
4x1 = 4 u |
Change |
|
+ 900 mℓ |
After |
1x3 = 3 u |
2x3 = 6 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
= 6 u - 4 u
= 2 u
2 u = 900
1 u = 900 ÷ 2 = 450
Volume of syrup that Mrs Reggie used
= 3 u
= 3 x 450
= 1350 mℓ
Answer(s): 1350 mℓ
