Hello Roland.

Let's take a look at your question.

There is something that is not clear in the wording. Watching the answers, this PS should be solved like this:

In each case, the orange candy is the cheapest, therefore in both cases, the discount will be 30 cents. Hence, the difference is $0. The correct answer is A. But, according to the wording, the way it should be solved is the following: We have that: - Each orange candy costs 30 cents. - Each strawberry candy costs 40 cents. If a customer buys: - 2 strawberry candies and an orange candy, the total cost will be 110 cents. - 2 orange candies and a strawberry candy, the total cost will be 100 cents. Since we know that the store gives the following offer: if a customer buys three candies then the cheapest amongst them will not be charged for, hence the amount paid for each customer is: - 2 strawberry candies and an orange candy, the new total cost is 80 cents. - 2 orange candies and a strawberry candy, the new total cost is 70 cents. This implies that the percentage paid for each customer is: $$-\ P_1=\frac{80\cdot100}{110}\approx73\%\ \ \ \ \Leftrightarrow\ \ discount_1=27\%.$$ $$-\ P_2=\frac{70\cdot100}{100}\approx70\%\ \ \ \ \Leftrightarrow\ \ discount_2=30\%.$$ The difference in the discount is 3%. I hope these explanations may help you. I'm available if you'd like a follow-up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.

With the current deal, if 2 strawberry candies and an orange candy are purchased then the orange candy wonâ€™t be charged. If 2 orange candies and a strawberry candy are purchased then one of the orange candies won't be charged.

Thus, the difference in the discounts will be zero.
