In a mixture of 60 liters, the ratio of milk and water is 2 : 3. What amount of water must be added to make the ratio of milk and water 1 : 2?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 12 litres.
In a mixture of 60 liters, the ratio of milk and water is 2 : 3
Milk = 2/5 × 60 = 24 liters
Water = 3/5 × 60 = 36 liters
Now,
The amount of water must be added to make the ratio of milk and water 1 : 2
Let the water added be x
⇒ 24/(36 + x) = 1/2
⇒ 48 = 36 + x
⇒ x = 12
So, 12 liters of water must be added
