Show the answer and the worked solution
Correct answer: C. 4%
Worked solution
- Gain = 28.60 − 27.50 = ₹1.10.
- Gain % = 1.10 / 27.50 × 100 = 4%.
Answer: 4%.
The idea
Profit percent is always measured on the cost price unless a question says otherwise. Divide the gain by the cost, never by the selling price.
Shortcut. 27.50 × 4 = 110, so the ₹1.10 gain is 110/2,750 = 1/25 of the cost — exactly 4%.
Common trap. 3% — dividing the ₹1.10 gain by the selling price 28.60 gives about 3.8%, and truncating that lands on 3%.
