Explanatory Answer   Quick Approach: Assume cost price as $100 and solve   Let the cost price of the goods 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.   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 100 +  50=

$150.   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= Discount/Marked Price∗100=50/150∗100= 33.33%   Choice 33.33%
