In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for the both quantities and choose the correct option. Quantity A: A shopkeeper earned a profit of 11.5% on a product after selling it at a discount of 10%. At what percentage above the cost price did he marked the price of the product? Quantity B: A shopkeeper marked a product at 45% above its cost price. After selling it at a certain discount, he earns a profit of 15%. Find the discount percentage.

Quantity B: A shopkeeper marked a product at 45% above its cost price. After selling it at a certain discount, he earns a profit of 15%. Find the discount percentage. Correct Answer Quantity A > Quantity B
Solving for Quantity A:
Let the cost price be Rs. ‘x’
Profit = 11.5% of x = 0.115x
Selling price = Cost price + profit = x + 0.115x = 1.115x
Now, Marked price - Discount = Selling price
⇒ MP - 10% of MP = 1.115x
⇒ 0.9MP = 1.115x
⇒ MP = 1.115x/0.9 = 1.24x
⇒ MP = (100 + 24)% of x
The marked price of the product is 24% above its cost price
⇒ Quantity A = 24%
Solving for Quantity B:
Let the cost price be Rs. ‘x’ and the discount be ‘d’%
Profit = 15% of x = 0.15x
Selling price = Cost price + profit = x + 0.15x = 1.15x
Marked price = (100 + 45)% of x = 1.45x
Now, Marked price - Discount = Selling price
⇒ 1.45x - d% of 1.45x = 1.15x
⇒ (d/100) × 1.45x = 1.45x - 1.15x
⇒ d = (0.3x/1.45x) × 100 = 20.7%
⇒ Quantity B = 20.7%
∴ Quantity A > Quantity B
