E Correct answer
Explanation

Let X bought at Rs 350/kg, Y at Rs 360/kg. Let quantity of X = q kg, Y = (q+40) kg. Selling price is Rs 400/kg for the mixture. But we don't know the total quantity or what the mixture ratio is. We cannot determine cost price per kg of the mixture without knowing the total weight and selling price structure.
