The water and milk are in the ratio 1 : 3. How much water should be added to 12 liters of the mixture to make the ratio 2 : 3?
- 2 liters
- 3 liters
- 4 liters
- None of these
Explanation
In 12 L mixture with ratio 1:3:
Total parts = 1 + 3 = 4
Water = (1/4) × 12 = 3 L
Milk = (3/4) × 12 = 9 L
Let x liters of water be added. Milk stays 9 L.
New ratio: (3 + x) : 9 = 2 : 3
So (3 + x)/9 = 2/3
3(3 + x) = 18
9 + 3x = 18
3x = 9
x = 3
