### HideShow timer Statistics

11) Throughout last year, a stylish jacket had a full price of P in certain store. At the beginning of this year, the regular full price of the jacket rose A% percent. Shortly after the beginning of this year, this store had a sale, and Margarette bought the jacket at B% less than then this year’s current full price, where B > A. How much did Margarette save, buying the jacket this year on sale, as compared to what she would have spent last year?

Statement #1: P = $250 Statement #2: B – A = 5 For a full explanation, see #11 in the second half of this post: http://magoosh.com/gmat/2013/gmat-sampl ... questions/ Let me know if there are any questions.

B – A = 5

case 1:

B=90 A=85
250(185%)10%= price1

case 2

B=10 A=5
250(105%) 90% = price2

clearly
(P-price1) does not equal (P-price2)
So we cannot determine how much she saved.
