Question
A milkman purchases 25 liters of milk from a dairy for
Rs.800 and sells it at the rate of 33.50 per liter. What is the profit or loss %? (rounded off)Solution
CP of 25 liters of ilk = Rs 800 SP of 25 literss of milk = 800/25 = Rs 33.5 SP of 25 liters of milk = 25 x 33.5 = 837.5 Profit = 837.5 - 800 = 37.5 Profit % = 37.5 / 800 x 100 = 4.6875% = 4.7%
