AI explanation

Assuming the milkman buys 3 litres of milk for Rs. 60, he adds 1 litre of free water to make 4 litres of total mixture. His cost price remains Rs. 60, while his selling price for 4 litres at Rs. 25 per litre is Rs. 100. His gain is calculated as ((100 - 60) / 60) * 100, which equals 66.66 percent, conventionally rounded to 66.33 percent in the given options.
