Explanation

The milkman buys 18 liters at Rs 10/liter (Total cost = 180). He sells 18 liters, but uses a 900ml measure for every liter, effectively selling 18 * (1000/900) = 20 liters worth of milk at Rs 12/liter. Total revenue = 20 * 12 = 240. Profit = 240 - 180 = 60. Profit percentage = (60/180) * 100 = 33.33%.

AI explanation

The total cost price for 18 litres of milk is 18 multiplied by Rs. 10, which equals Rs. 180. He sells this milk using a 900 ml measure, so he gets 1800 divided by 900, which equals 20 measures, and his total selling price is 20 multiplied by Rs. 12, totaling Rs. 240. The profit is 240 minus 180, which is Rs. 60, and the profit percentage is 60 divided by 180 multiplied by 100, equalling 33 1/3%. The profit is Rs. 60 and the profit percentage is 33 1/3%.
