A mixture contains 36 litres of milk and water in the ratio 2:1.
How much water must be added to make the ratio 1:1?
Show answer & explanation
Correct answer: A
Explanation
Total mixture = 36 liters; Milk : Water = 2 : 1
Total parts = 2 + 1
Milk = (2/3) × 36 = 24
Water = (1/3) × 36 = 12
Let 'x' liters of water be added.
New ratio = 24 : (12 + x) = 1 : 1
24 = 12 + x
x = 12 liters
