一道簡單數學題, 答不對者不適合理財

Duye不小心沒看清表情符號從商店收到一張100元假鈔，Duye想阿，要不俺也賭一把，看能否用掉。

一天Duye來到全不懂的店裏買了一件禮物。這件禮物是全不懂花18元從毛毛媽那進的貨，標價是21元。

結果Duye掏出100元要買這件禮物。 全不懂當時沒有零錢，用那100元向隔壁開免稅店的笨企鵝換了100元的零錢，找給Duye79元。

但是笨企鵝後來發現那100元是假鈔，全不懂無奈還了笨企鵝100元。

現在問題是：全不懂在這次交易中到底損失了多少錢 ?

答案在這

100+79+18=197

[Coco_lau]

100+79+15=194

97元，加上賺3元的生意機會。

太複雜了，算不清。

[大家幫我買房]

全不懂's credit ratings will be downgraded. He lost huge. 笨企鵝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 禮物, he would not buy one again from 全不懂. When 全不懂 went to 笨企鵝'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.

損失了97元，18＋79＝97元。

[caterpilllar]

79+18=97

[caterpilllar]

他一共損失：100+18=118元-賺了3元=一共損失115元

全不是答案.

Correct 答案 is ZERO.

[xintong2006]

197？

[dentdoc]

100+21+79=200

[williamyuan]

改正一下，損失了97元，18＋79＝97元。

[許諾]

100+79+18=197

[patrick168]

買禮物的18元和給笨企鵝的100元共118元.

[mibaby]

79 add 18 is 97.Is right ?

[svcz0511]

損失了100元

[williamyuan]

損失了100元，21元＋79元＝100元。

[easyrude]

全不懂收了：100 （假）
付出了：79 （找錢） + 100

總共賠了179

[如果可以再來一次]

197
