In a mixture 60 litres, the ratio of milk and water 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is

  1. 80 litres
  2. 60 litres ✓
  3. 40 litres
  4. 10 litres
Explanation

In 60 litres with milk : water = 2 : 1, milk = 40 litres and water = 20 litres.

For milk : water = 1 : 2, water must be double the milk, so 80 litres. Water to add = 80 − 20 = 60 litres.
