D Correct answer
Explanation

Initial mixture: 48 liters, ratio 7:5. Milk = 28, Water = 20. Let x be milk added. (28+x)/20 = 3/2. 56 + 2x = 60. 2x = 4, x = 2.

AI explanation

In the initial 48 litres, the quantity of milk is 7 divided by 12 multiplied by 48, which is 28 litres. Let the added milk be x litres, so the new equation becomes 28 plus x divided by 20 equals 3 divided by 2. Solving for x gives 56 plus 2x equals 60, meaning x is 2 litres.
