A merchant bought an item for $80. He marked it up by 25% and then offered a 10% discount on the marked price. What was his profit percentage?

A 12.5%
B 15%
C 18%
D 22.5%

✓ Correct Answer: Option A

Cost Price (CP) = $80. Marked Price = $80 * (1 + 0.25) = $100. Selling Price (SP) = $100 * (1 - 0.10) = $90. Profit = SP - CP = $90 - $80 = $10. Profit Percentage = ($10/$80) * 100% = 12.5%.
