B Correct answer
Explanation

Total mixture = 15 kg milk + 3 kg water = 18 kg. Total value = 18 kg * 22 Rs/kg = 396 Rs. Since water is free, the 396 Rs is the cost of the 15 kg of milk. Cost price per kg = 396 / 15 = 26.40 Rs.

AI explanation

The total weight of the mixture is the 15 kg of milk plus the 3 kg of water, which equals 18 kg. At a price of 22 rupees per kg, the total value of the mixture is 18 multiplied by 22, resulting in 396 rupees. Because the water is free, this entire amount represents the cost of the 15 kg of milk, so dividing 396 by 15 gives the original cost of the milk as 26.40 rupees per kg.
