Explanatory Answer | GMAT Profit Loss Discount Q13

Step 1: Assume cost price and compute marked price

Approach: Assume cost price to be $100.

She had initially marked her goods up by 50%.
Therefore, a 50% mark up would have resulted in her marked price being $100 + 50% of $100 = $100 + $50 = $150.

Step 2 : Compute the % discount offered

She finally sells the product at no profit or loss.
i.e., she sells the product at cost price, which in this case is $100.
Therefore, she offers a discount of $50 on her marked price of $150.

Hence, the % discount offered by her = \\frac{\text{Discount}}{\text{Marked Price}} × 100 = \frac{50}{150} × 100)= 33.33%
Discount offered is 33.33%

Choice E is the correct answer.
