Let us take 1 litre as the quantity purchased
Purchase price = Rs 12 / litre total purchase cost = Rs 12.
amount of liquid after mixing water = 1 litre milk + 25 % = 1 + 25/100 = 1.25 litre
Selling price = Rs 15/litre
Total money earned from sales = price * quantity = Rs 15 * 1.25 = Rs 18.75
Profit earned = money earned - cost = 18.75 - 12 = Rs 6.75
Profit percent = profit * 100 / purchase cost = 6.75 * 100 / 12 = 56.25 %
Purchase price = Rs 12 / litre total purchase cost = Rs 12.
