An egg seller sells his eggs only in the packs of 3 eggs, 6 eggs, 9 eggs, 12 eggs etc., but the rate is not necessarily uniform. One day Raju (which is not the same egg seller) purchased at the rate of 3 eggs for a rupee and the next hour he purchased equal number of eggs at the rate of 6 eggs for a rupee. Next day he sold all the eggs at the rate of 9 eggs for Rs. 2. What is his percentage profit or loss?

A) 10% loss
B) 11.11% loss
C) 3% loss

Solution: CP of one egg in first case = 1/3 = 33.33 paise   CP of one egg in second case = 1/6 = 16.66 paise   Average CP = (33.33 +16.66)/2 = 25 paise   Selling price of 9 eggs = Rs. 2   SP of one egg = 200/9   Profit or loss = [(25 - (200/9))*100]/25   Profit or loss = -11.11. (loss)   Answer: Option 11.11% loss
