E Correct answer
Explanation

To find profit %, we need cost price and selling price per unit. II gives milk cost Rs.35/L, so water cost Rs.25/L (10 less). Selling price is Rs.40/L. But profit depends on the milk-water ratio, which is NOT given in any statement. Statement III (80 liters sold) doesn't help find the mixture composition. Even with all three statements, the ratio is unknown.
