A retailer marks all his goods at 50% above the cost price and thinking that he will still make 25% profit, offers a discount of 25% on the marked price. What is the actual profit he earns on his sales?

Correct option is C

Given:
Goods marked above Cost price = 50%
Discount offered = 25%
Solution:
Let the Cost Price of article be 100
Then marked price of goods = 100 + 50% of 100 = 100 +50 = 150
If a discount of25% is offered then selling price = 150 - 25% of 150 = 150 -37.5 = 112.5
Profit = 112.5 - 100 = 12.5
Profit percentage = 12.5/100 × 100 = 12.5%
