1.	A woman bought 50 dozen eggs at Rs 6.40 a dozen. Out of these 20 eggs were found to be broken. She sold the remaining eggs at 55 paise per egg. Find her gain or loss percent.
Answer» Given cost of one dozen eggs = Rs. 6.40 Cost of 50 dozen eggs = 50 x 6.40 = Rs. 320 Total number of eggs = 50 x 12 = 600 Number of eggs left after removing the broken ones = 600 – 20 = 580 SP of 1 egg = 55 paise So, SP of 580 eggs = 580 x 55 = 31900 paise = Rs. 31900/100 = Rs. 319 Loss = CP – SP = Rs. (320 – 319) = Rs. 1 Loss % = (Loss/CP) x 100 = (1/320) x 100 Loss = 0.31%

Answer»

Given cost of one dozen eggs = Rs. 6.40

Cost of 50 dozen eggs = 50 x 6.40 = Rs. 320

Total number of eggs = 50 x 12 = 600

Number of eggs left after removing the broken ones = 600 – 20 = 580

SP of 1 egg = 55 paise

So, SP of 580 eggs = 580 x 55 = 31900 paise

= Rs. 31900/100

= Rs. 319

Loss = CP – SP

= Rs. (320 – 319) = Rs. 1

Loss % = (Loss/CP) x 100

= (1/320) x 100

Loss = 0.31%
