Duye不小心没看清表情符号从商店收到一张100元假钞,Duye想阿,要不俺也赌一把,看能否用掉。

一天Duye来到全不懂的店里买了一件礼物。这件礼物是全不懂花18元从毛毛妈那进的货,标价是21元。

结果Duye掏出100元要买这件礼物。 全不懂当时没有零钱,用那100元向隔壁开免税店的笨企鹅换了100元的零钱,找给Duye79元。

但是笨企鹅后来发现那100元是假钞,全不懂无奈还了笨企鹅100元。

现在问题是:全不懂在这次交易中到底损失了多少钱 ?

答案在这

全不懂's credit ratings will be downgraded. He lost huge. 笨企鹅will never lend him money any more. Now all the people know that 全不懂 is stupid and can be fooled easily. It's like 全不懂 sent an invitation to all the people to cheat him in the future. He will most likely be the next victim of fraud again. 全不懂 lost business opportunity also, because after Duye got the 礼物, he would not buy one again from 全不懂. When 全不懂 went to 笨企鹅's store, 3 other potential customers walked away. Of course, 全不懂 lost $97 cash immediately after the trade. But he lost much more than that as the victim of the fraud.

全不懂收了:100 (假)

总共赔了179
