pace慢的题4反思：
selling price: N, W
listing price: 0.5N, 0.4W
题干问的是what percent (more or less) of the selling price in Store N is the selling price of the item in Store W？也就是问(N-W)/W等于多少？
由这句话 If the list price of the same item is 20 percent higher in Store W可得：0.5N=1.2*0.4W，也就是N=0.96W
所以，(N-W)/W=（0.96W-W）/W=-0.04=4%loss

sell price 是打折后的price， list price 是打折前的price. 60% discount, 是打四折

list price：N和W，打折后的selling price：0.5N和0.4W。因为W的list price比N高20%，所以W=1.2N。求 (N的sell price - W的sell price)/W的sell price。代入可得，(0.5N-0.4W)/0.4W = (0.5N/0.4*1.2N)-1=1/24，结果只是约等于4%，而且是正数，根本不是less。到底哪里错了啊？

嗷，of后面跟的时分母，分母是0.5N。。。所以等式应该是(0.5N-0.4W)/0.5N = 1- 0.4*1.2/0.5 = 1/25，咱们还是正数啊？啊！

selling price是list price打折后的价格吧，那应该store N是N*0.5,store W不该是N*1.2*0.4=0.48N吗，为什么答案N的价格比W低？

摘自gmatclub: 感觉这样好理解一些。We can let the list price of the item in store N = 100; thus, the list price of the same item in store W = 120. The selling (or discounted) price of the item in store N is 0.5 x 100 = 50, and the selling (or discounted) price of the same item in store W is 0.4 x 120 = 48. Therefore, the selling price in store W is (50 - 48)/50 x 100 = 2/50 x 100 = 4 percent less than that in store N. Answer: B

题目 list price N W 说售价 是分别打五折和四折 所以 selling price 是 0.5N 0.4W 又说 W 的list price 高0.2 则 list price 又变成 N 和 W=1.2N 问：selling price 比N 多或者少 多少percent 是 M 则求(M-N)/N 所以 （1.2*0.4N-0.5N）/0.5N=0.48/0.5-1=-0.04 也就是4%less

题目有两个地方都读错了。首先，60%discount on listing price的意思是listing价格减少60%，打四折；其次最后的问题不是求N/W是多少，注意那个（more or less），应该是（N-W）/W

what percent more or less （of the selling price in Store N） is the selling price of the item in Store W? 实际上问的是W的售价比N的售价多或者少多少百分比？所以是N-W/N。
