During a sale, for each shirt that Mark purchased at the regular price, he also purchased a shirt at half the regular price. How many shirts did Mark purchase during the sale?
(1) The regular price of each of the shirts that Mark purchased during the sale was $21.50.
(2) The total of the prices for all the shirts that Mark purchased during the sale was $129.00.
--------------------------------------------------------------------------------------------------------------------------------------------------------
【答案】C
【思路】S=?
(1) P=21.5 ---------------------------------------------------------------------insufficient
(2) S P+1/2 P=129-------------------------------------------------------------------- insufficient
(1)(2)解联立得X -------------------------------------------------- sufficient
--------------------------------------------------------------------------------------------------------------------------------------------------------
我也是这么做的,可是当时做题的时候的出来X=5.5, 因为我觉得gmat数学应用题比较联系生活啊,衬衫不可能0.5件来买啊,所以选了E
那么GMAT数学中的得数可以求出但是与事实不符可以么?
