Three cups of Milk from the first container is taken out and is mixed well in the second container. Then, three cups of this mixture is taken out and is mixed in the first container. Quantity 1: Proportion of water in first container Quantity 2: Proportion of Milk in second container

  1. Quantity I > Quantity II

  2. Quantity I < Quantity II

  3. Quantity I ≥ Quantity II

  4. Quantity I ≤ Quantity II

E Correct answer
Explanation

This is a mixture transfer problem. Container 1: 600 ml Milk. Container 2: 600 ml Water. After transferring 3 cups milk to container 2 and mixing, then transferring 3 cups of mixture back, due to the symmetric transfers and equal initial volumes, the final proportion of water in container 1 equals the final proportion of milk in container 2. Quantity I = Quantity II.
