V2【alextan2010】印象最深刻，因为一直读不懂。说一个商品的利润有30%的成本和24% from cost of changing selling price组成，然后sellingprice现在是$274而成本没有变，问之前的selling price是多少？答案有180 190多 200多，我乱选了190。（害我出了一身冷汗，好紧张，后面时间少了）难道是JJ176？ 作者: 梦离ouzi 时间: 2011-11-13 11:06
V1 的话很明确啊。 英文应该是这样 。 A product's profit had been 12% of total cost, however, recently it had increased to 30% of total cost at the price of $292, assuming cost did not change, what was the original price?
So simply [292/(1.3)]*1.12 估计号码有误。作者: kakaxihx 时间: 2011-11-13 11:41
