A Correct answer
Explanation

Statement I: If profit is 20% when selling at cost price after adding water, it means water added is 20% of milk quantity (since selling 120 units at the price of 100 units gives 20% profit). So milk:water = 100:20 = 5:1. Statement II only gives selling price (Rs.25/Litre) without cost price or profit percentage, making the ratio impossible to determine. Therefore, only Statement I is sufficient.
