please provide the detailed solution.

Question:

A milkman bought 15 L of milk and mixed 3 L of water in it. If the price per kg of the mixture becomes Rs.22, what is the cost price of the milk per litre?

Options:
A) ₹28.00
B) ₹26.40
C) ₹24.00
D) ₹22.60
Solution:
Ans: (b)

Cost of 1 kg of mixture = Rs. 22
Cost of (15 + 3) kg of mixture = (18 * Rs 22) = Rs. 396
As water is free so Rs. 396 is the actual cost of 15 kg of milk 
so cost of 1 kg of milk = (396 /15) = Rs. 26.40
