Tank B and Tank C had some syrup in the ratio 9 : 4. After 23 litres of syrup was transferred from Tank B to Tank C, the volume of syrup in Tank C became 3 times as much as in Tank B. How much syrup were there in the two tanks in all?
|
Tank B |
Tank C |
Total |
Before |
9x4 = 36 u |
4x4 = 16 u |
13x4 = 52 u |
Change |
- 23 |
+ 23 |
|
After |
1x13 = 13 u |
3x13 = 39 u |
4x13 = 52 u |
The total volume of syrup in the tanks remained unchanged. Make the total volume at first and in the end the same. LCM of 4 and 13 is 52.
Amount of syrup transferred from Tank B to Tank C
= 36 u - 13 u
= 23 u
23 u = 23
1 u = 23 ÷ 23 = 1
Total volume of syrup in two tanks
= 52 u
= 52 x 1
= 52 ℓ
Answer(s): 52 ℓ
