Question

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 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
• D. 2.5% profit

Answer 1

The correct option is B 11.11% loss

CP of one egg (in first case) $=\frac{1}{3}$ = 33.33 paise
CP of one egg (in second case) $=\frac{1}{6}$ = 16.66 paise
Averge CP of one egg $=\frac{33.33+16.66}{2}$ = 25 paise
SP of one egg $=\frac{200}{9}$
(Re. 1 = 100 paise)
profit - loss $=\frac{25-\frac{200}{9}}{25}\times 100$ $(loss\%=\frac{CP-SP}{CP}\times 100)$
=11.11% loss
