Riya purchased \(2\frac{1}{2}\) dozen eggs at the rate of Rs 20 per dozen. She found that 6 eggs were rotten. She sold the remaining eggs at the rate of Rs 22 per dozen. Her profit or loss percentage is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 12% loss
She paid for all the eggs but could sell only the good ones, so compare the money she paid for all 30 eggs with the money she got for the eggs she sold.
\(2\frac{1}{2}\) dozen \(=30\) eggs; cost price \(\displaystyle =2\frac{1}{2}\times20=\) Rs 50
Eggs left \(=30-6=24=2\) dozen
Selling price \(=2\times22=\) Rs 44
Loss \(=50-44=\) Rs 6
Loss per cent \(\displaystyle =\frac{6}{50}\times100=12\)%
Riya makes a loss of 12%.
