GRE percentages / discount question

The following is a practice question from a GRE preparation book.

A case of $100$ candy bars is sold at a discount of $\$0.36$per bar. Quantity A: the discount per case Quantity B: 36% (a) A is greater (b) B is greater (C) The two quantities are equal (d) The relationship cannot be determined from the information given My approach: Quantity B is 36%, which is simply 0.36 Quantity A is 0.36 * 100 = 36 Therefore A > B. However the answer I'm given is D. Where have I made a mistake? • You don't know what a bar costs, so you don't know the percent discount. – dxiv Jan 7 '18 at 7:24 • Perhaps I don't understand the meaning of 'discount per case' clearly. Should not just mean the discount per 100 bars? Why is the % discount relevant? – rayanisran Jan 7 '18 at 7:37 • Your answer would have been correct if Quantity B had said$\,\$0.36\,$, instead. But it does not, it says $\,36\%\,$, which is presumbaly to be interpreted as the percent discount off a box of candies. – dxiv Jan 7 '18 at 7:40
• Was subtle to me. Thanks. – rayanisran Jan 7 '18 at 7:50
