D Correct answer
Explanation

Selling price = 48, gain = 10%, so Cost Price = 48 / 1.1 = 43.63. We have two types of milk: 61/kg and an unknown cost for the 100kg. Without the cost of the second type, the mixture ratio cannot be determined.

AI explanation

The cost price of the mixed milk is calculated as 48 divided by 1.10, which gives Rs 43.63 per kg. Although the Rs 61 per kg milk is mixed with a 100 kg unknown quantity, there are two unknowns in this scenario: the price of the second milk and the required quantity of the first milk. With only one equation from the mixture cost, a unique solution cannot be found. Therefore, the answer cannot be determined from the given data.
