If 50% of 2:3 solution of milk and water is replaced with water, then the concentration of the solution is reduced by?

Step-by-step explanation:

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. Hence the solution is reduced by 50%.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
