D Correct answer
Explanation

Let the cost price of 5 liters of pure milk be 5x. The selling price of 6 liters of the mixture (5 liters milk + 1 liter water) is 6 * 2x = 12x. Profit = 12x - 5x = 7x. Profit percentage = (7x / 5x) * 100 = 140%.

AI explanation

Assume the cost price of 5 litres of pure milk is 5x. By adding 1 litre of water, the total volume becomes 6 litres, which is sold at 2x per litre to give a selling price of 12x. The profit is 12x minus 5x, which equals 7x. Using the profit percentage formula, (Profit / Cost Price) multiplied by 100, we get (7x / 5x) multiplied by 100, resulting in 140%.
