Let the quantity of milk and water be 40 and 60 respectively
After removing 50% of solution
Quantity of milk = 20 and quantity of water = 30
Therefore, the concentration of the solution is reduced from 40 to 20 i.e., reduced by 50%

Solution:

Given, the ratio of milk and water in the solution is 2:3.

Let the quantity of solution be 5 units (2 units of milk and 3 units of water).

After replacing 50% of the solution with water, the quantity of water in the solution becomes (3/2) units (as half of the water is replaced with water).

The total quantity of the solution after replacement becomes (2 + 3/2) = 7/2 units.

The new ratio of milk and water in the solution is 2:2.5 or 4:5.

Therefore, the concentration of the solution is reduced by (5 - 4)/5 = 1/5 or 20%.

Hence, the correct option is (C) 50%.
