\(100 \) oranges are bought at the rate of \(Rs. 350\) and sold at the rate of \(Rs. 48\) per dozen. The percentage of profit or loss is:
Answer: A
Cost Price of 1 orange \(= Rs. (\frac{350}{100}) = Rs. 3.50\)
Selling Price of 1 orange \(= Rs. (\frac{48}{12}) = Rs. 4\)
\(\therefore\) Gain % = \((\frac{0.50}{3.50} \times 100)\) % \(= \frac{100}{7}\) % \(= 14\frac{2}{7}\) %
