Q. A shopkeeper marks shirts at 25% above cost price then allows a discount of 10%. What is the profit or loss % ?
Assume Cost Price: Let's assume the cost price of the shirt is $100 (it makes the math easier).
Calculate Marked Price: First, calculate the marked price which is 25% above the cost price. So, 25% of $100 is $25.
Add Marked Price: Add the $25 to the original cost price to get the marked price: $100+$25=$125.
Calculate Discount: Now, the shopkeeper gives a 10% discount on the marked price. 10% of $125 is $12.5.
Subtract Discount: Subtract the discount from the marked price to find the selling price: $125−$12.5=$112.5.
Find Profit/Loss Percentage: To find the profit or loss percentage, we compare the selling price to the cost price. The selling price is $112.5 and the cost price was $100.
Calculate Profit: Calculate the profit by subtracting the cost price from the selling price: $112.5−$100=$12.5.
Calculate Profit Percentage: The profit percentage is the profit divided by the cost price, then multiplied by 100. So, ($12.5/$100)×100=12.5%.
