Ask who will do it, and get the right answer

The correct answer is: $50.

On the whole, all the behaviors in the whole transaction process are fair except for the 50 yuan counterfeit currency, so the loss of the Xiaomi Bu children's shoe store should be 50 yuan.

Careful analysis, first of all, the Xiaomi Butong shoes store took 50 yuan of counterfeit money to the neighborhood to exchange 50 yuan for change, when the neighborhood knew that it was counterfeit money, the Xiaomi Butong shoes store lost 50 yuan, so this process can be understood as: Xiaomi Butong shoes store took 50 yuan of real money to the neighborhood to exchange 50 yuan for 50 yuan change, this link Xiaomi Butong shoes store has no loss. In addition, the transaction between the millet step children's shoe store and the young people, it is also the main link, the young people use 50 yuan counterfeit money (that is, they did not spend a penny) from the millet step children's shoes store to get a pair of shoes with a cost of 15 yuan and the recovered 29 yuan in cash, which is the loss of the millet step children's shoes store, it should be 15 29 44 yuan, if this is the case, the friend on the 6th floor will answer correctly, but is this really the case?

No. Because, the Xiaomi Butong shoe store is traded with young people at 21 yuan, so if it is calculated at 15 yuan, the Mi Butong shoe store will lose 6 yuan of profit, therefore, the loss of the Xiaomi Butong shoe store in this transaction should be 15 29 6 50 yuan.

44 yuan. As for the other Taibai Immortals, it has been said very clearly.

And the loss of shoes, I think it should be 15 yuan. Because the shoes were bought by the owner for 15 yuan, then, she should have lost 15 yuan when she lost her shoes.

Yes, the shoes can make a profit of 6 yuan, but he can't guarantee that the shoes will be sold! Besides, if you can guarantee that the shoes will not be bought within three days (if there is no accident), and the owner is planning to raise the price in two days, and now he has been cheated, then the shoe store will lose even more after the price increase (note that the loss will be even greater after the incident).

Therefore, the loss of shoes should be 15 yuan.

Please think about it, if the loss of the owner reports that the loss of shoes is 15 yuan, and after solving the case, he gets 15 yuan, and then buys a pair of shoes, will there be no loss?

If you report 21 yuan, and get 21 yuan, you have 6 yuan left after buying a pair of shoes, and you lose a pair of shoes, but you get the same shoes and 6 yuan.

Isn't it inconsistent?

Since you can't decide, take a look at a traditional story.

Isn't it ridiculous that someone killed a neighbor's cat and the neighbor demanded that he pay (as if it were) 10 taels of rice, on the grounds that the cat could eat a lot of mice and thus save a lot of crops--- isn't that ridiculous?

Store expenses 50 + 29 + 15 = 94 yuan.

Income 21-15=6 yuan.

So the loss: 94-6=88 yuan.

That is to say, the shopkeeper collected counterfeit banknotes, but did not receive the bill, first lost the cost of the shoes 15 yuan, then found a buyer 29 yuan, and returned 50 yuan to the neighborhood. This was all lost by the shopkeeper, so a total loss of 94 yuan.
