A trader marks his goods at 45% above the cost price. He offers a discount of 21% to his customers. What is his percentage profit (rounded off to the nearest integer)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 15%.
Calculations:
Let the cost price be 100x
Marked price = 145% of 100x = 145x
Selling price after a discount of 21%
Selling price = 145x × 79% = 114.55x
Profit = 114.55x - 100x = 14.55x
Profit % = (14.55x/100x) × 100
⇒ 14.55% or 15% (approx.)
