一道简单数学题, 答不对者不适合理财

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

[Coco_lau]

100+79+18=197

[Coco_lau]

100+79+15=194

[fran]

97元，加上赚3元的生意机会。

太复杂了，算不清。

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.

损失了97元，18＋79＝97元。

[caterpilllar]

79+18=97

[caterpilllar]

他一共损失：100+18=118元-赚了3元=一共损失115元

全不是答案.

Correct 答案 is ZERO.

nothing really happened.

no witness. case dismissed.

[xintong2006]

197？

[dentdoc]

100+21+79=200

[williamyuan]

改正一下，损失了97元，18＋79＝97元。

[许诺]

100+79+18=197

[patrick168]

买礼物的18元和给笨企鹅的100元共118元.

[mibaby]

79 add 18 is 97.Is right ?

[svcz0511]

损失了100元

[williamyuan]

损失了100元，21元＋79元＝100元。

[easyrude]

全不懂收了：100 （假）
付出了：79 （找钱） + 100

总共赔了179

[如果可以再来一次]

197
