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:

Given Data

• Total oranges bought = 100
• Total cost (cost price, CP) = Rs. 350
• Selling rate = Rs. 48 per dozen (12 oranges)
• Required: overall percentage of profit or loss

Step 1: Compute total selling price (SP)
Price per orange = 48 ÷ 12 = Rs. 4SP for 100 oranges = 100 × 4 = Rs. 400

Step 2: Compute absolute profit
Profit = SP − CP = 400 − 350 = Rs. 50

Step 3: Profit percentage on cost
Profit% = (Profit ÷ CP) × 100 = (50 ÷ 350) × 100= 0.142857… × 100 ≈ 14.29% profit

Checks & Common Pitfalls

• Always convert the dozen rate to a per unit price before scaling.
• Profit% is always computed on cost, not on selling price (unless explicitly asked).
• Ensure rounding is consistent to two decimals for percentage reporting.

Final Answer
Overall result is a 14.29% profit.
