One day, a young man came to Boss Wang s shop and bought a gift

100 yuan! It's about this deal.

21-18=3 List Price - Cost = Profit.

100 yuan fake for 100 yuan real Boss Wang lost 0, neighbor lost 100100 yuan true - found out 79 - gift 21 + profit 3 = 3 neighbor lost 100 Boss Wang lost 0 income 3

Boss Wang also returned 100 neighbors, neighbors lost 0, Boss Wang lost 100, minus 3 of the receipts, equals 97

Boss Wang's loss is the young man's gain: a gift + change found.

The cost of the gift is 18 + change 79 = 97

Let's say the boss doesn't have a penny in his hand and doesn't have the goods before he buys them.

His dealings with his neighbors are smoke, leave it alone.

Even if the price is 210,000 (the practice of today's businessmen making profits) is irrelevant to this question, because the young man pays a worthless counterfeit bill, which means that the boss actually gets 0 money.

Borrow 100 yuan and exchange it for 18 yuan + 79 yuan + 3 yuan = 100 three copies;

The cost of the gift is 18 yuan when the goods are purchased, and 79 yuan is given to the young man when the goods are sold, and the young man leaves with both things at the same time;

The boss had only $3 left in his drawer and a worthless counterfeit bill;

Suppose he borrowed 100 yuan from a neighbor, and now he has to pay 97 yuan out of pocket to repay the debt.

In other words, the boss lost 97 yuan.

A little thought: It is recommended to say "customer" in this question, not "young people", as if there is a suspicion of slander, and they all say that "ginger is old and spicy".

The loss was 194 yuan.

The reasoning is as follows: lose 100 fake money because you have to pay back your neighbors.

The loss was 79 yuan, because I found **.

loss of $18, cost of goods.

This adds up to 79 + 100 + 18 = 197

But he sold 21 goods, so he earned 3 yuan.

The last 197-3 = 194 yuan.

Boss Wang lost 194 yuan.

100 yuan for a neighbor, 79 yuan for a young man, 18 yuan for the toy, 21 yuan for the toy, and 3 yuan for the toy.

The net income of 3 yuan is put into the cost of toys and wants to deduct 3 yuan, so the money lost on toys is only 15 yuan.

Therefore, (find 79 yuan + 18 yuan - net profit of 3 yuan = loss of 94 yuan).

First of all, I earned 3 yuan in terms of gifts, and then the neighborhood borrowed 100 to repay 100, and I didn't owe it.

The main thing is that the young man gave 100 yuan in counterfeit money, and here he lost 100 yuan.

The loss of 100 yuan minus the 3 yuan earned, so it is a loss of 97 yuan.

Mathematics is a general means for humans to strictly describe the abstract structure and pattern of things, and can be applied to any problem in the real world, and all mathematical objects are inherently artificially defined.

97 yuan. You can treat the fake as a loss, which is equal to a loss of 100And three of the 100 yuan are earned, which is equal to -100 + 3 = 97

The first answer: a loss of $100.

The price is 21 yuan, and 79 yuan is found, for a total of 100 yuan.

The second answer: a loss of $97.

The cost is 18 yuan, and 79 yuan is found out, for a total of 97 yuan.

It's very simple, 79+18 97 yuan,,, you can think of it this way, Boss Wang lost a total of the cost of the gift, and found out the 79, the neighborhood that condition is a distraction. Wood influences.

The cash loss was 79 yuan and the cost loss was 18 yuan.

The direct loss was 97 yuan.

The opportunity cost loss is 3 yuan.

You can take the 100 yuan you borrowed from your neighbor as Boss Wang's own money (he later returned 100 yuan to your neighbor) The young man took 79 yuan in change and took an item that cost 18 yuan, and he lost 97 yuan.

As a result, the young man shelled out $100 for the gift.

Boss Wang had no change at that time, so he used the 100 yuan to exchange 100 yuan for 100 yuan from the neighborhood, and found 79 yuan for the young man.

But the neighborhood later found out that the 100 yuan was a counterfeit banknote, and Boss Wang had no choice but to return the neighborhood 100 yuan.

Now the question is: how much money did Boss Wang lose in this transaction?

This question? 97 yuan.

Simple algorithm Boss Wang gets 21-18=3 yuan.

Lost (returned to neighbors) 100 yuan.

The difference is 97 yuan

The kind of upside-down on the Internet is very confusing. According to the "gains and losses", that is, the income and expenditure, it will soon become clear

Performance loss: 79 + 18 = 97 (yuan).

Actual loss: 79 + 21 = 100 (yuan) (in this transaction, his labor income is 3 yuan, just imagine, if it is not because of the counterfeit money, will Boss Wang increase 3 yuan at this time?) Isn't that a loss? ）

Why do I get it wrong?

1, many people fell off the horse at "100 yuan". 197. In fact, the relationship between Boss Wang and the neighborhood is only the relationship between borrowing 100 yuan and repaying 100 yuan, and no one has gained or lost in the process.

2. Many people do not include the 3 yuan of labor earned in the transaction when calculating money. (97 yuan) This is like if you negotiate 100 yuan a month for a certain boss to work for a certain boss in advance, but you do something for him for a month, and he doesn't give you a penny, can you say that you have no loss in this incident? Can you say "because the 100 yuan didn't go into my pocket, so it's not mine, I don't have any loss", here Boss Wang's 3 yuan and your 100 yuan are the same thing.

Got it? These are the two main wrong locations.

Many friends obviously have no concept of the value-added of goods. If a product is given away, it will not add value. It only adds value if you buy and sell, that is, when you trade, because you pay for your labor in the transaction.

If Boss Wang's gift was given away, it would be a loss of 18 yuan, but here he traded it, and the transaction was obviously successful, that is, it had been sold. Thus his labor should be recognized, and it was recognized, that is, it was really sold for $21. It is a fact that he received counterfeit money, but you can't disown his labor because of that.

Boss Wang received 100 yuan of counterfeit money, which is actually equivalent to Boss Wang receiving 100 yuan of real money, but he accidentally dropped it. If you can think about it this way, you will understand how much yuan Boss Wang lost in this incident.

A total of 115 yuan was lost to Boss Wang.

The money exchanged with the neighbor can be used as a loan balance, take 100 and repay 100, you can ignore the young people to buy things, and exchange 79 yuan and 21 yuan worth of goods with a hundred yuan counterfeit banknotes, while Boss Wang paid 79 yuan in real banknotes and a cost of 18 yuan, and the price of 21 yuan was a commodity, the answer came out, Boss Wang lost 100 yuan, looking at the problem from the perspective of maximizing benefits, 21 yuan can be sold for something, calculated with 18 yuan, this 3 yuan is also a loss.

So I think the answer should be $100.

Boss Wang's lost money = the money earned by the young man = the cost of the gift of 18 yuan + the 79 yuan found for the young man = 97 yuan.

194 18 Gift capital 79** 100 Return to neighbor 3 Earn 194 6 200

21 earned 3 yuan in the supply and returned to the neighbor 100 li, that is, 97 318 3 earned 15

Earn 3 97 100 also next door.

I didn't know how to calculate it from these answers, and I got the number 197

I don't think you should look at the content of the interference, start from reality, and pretend that I am the king, then a fake bill means:

Meta things are lost.

2.I also found 79 yuan.

3.After that, he also lost 100 to others

So in the end a total of 197 was lost

I don't know if it's right, so think about it again!

176 yuan, calculated as:

1. The cost loss is 18 yuan.

2. Change is 79 yuan.

3. Compensate the neighbor 100 yuan.

4. Exchange 100 yuan for change, and 21 yuan after change.

Therefore, 18 + 79 + 100-21 = 176 yuan.

It should be 97 yuan, the neighbor didn't make your money, so you didn't lose money on the neighbor, only the buyer made your money, and took 18 products and 79 yuan.

It's just the math answer.

In reality, losses are calculated based on the selling price.

He gave his neighbor 100 yuan in counterfeit bills and repaid his neighbor 100 yuan, and he and his neighbor did not owe each other. He collected 100 yuan in counterfeit banknotes and returned 100 yuan to the guest, and he should have lost 100 yuan, but the profit was 3 yuan, so the loss was 100-3 = 97 yuan.

Calculated in this way: the cost is 18 + 79 + 100 = 197 plus the 3 + 3 = 203 yuan that should be earned, and the actual loss is: 203 yuan.

The cost price of the gift of 18 yuan, and the change of 79 yuan, a total loss of 97 yuan!

A total of 100 yuan was lost, of which 79 were lost by finding money for young people, 18 were lost in cost, and 3 yuan should have been earned. It means that the young man didn't pay a penny, and the boss gave him the goods and 79 yuan. You don't care about the change you exchanged with your neighbors, just treat it as if the change is yours, and the fake money is always in your hands, so you won't mistake it for a loss of 200.

How do you feel that none of the above answers are correct?

I'll do the math. Because it was a counterfeit banknote received.

1.Boss Wang lost a total of 18 yuan in cost of a piece of clothing, and then 79 yuan in cash to the young man, for a total loss of 97 yuan.

2.If the clothes are calculated according to the price of 20 yuan, Boss Wang has lost a total of 100 yuan.

200 yuan.

Because 197 is just a cost.

He also lost profits.

So it's 200

200 yuan.

179 yuan + 18 yuan cost + 3 yuan profit.

No, it should be 94.

It's $97. The whole transaction has nothing to do with the neighborhood, because the neighborhood did not make or lose money in the transaction, so it was ignored, because the young man gave.

Boss Wang. The $100 is.

Counterfeit banknotes. So it can be considered 0 yuan, that is, the young man got 79 yuan and a gift worth 18 yuan from Boss Wang without any payment, so Boss Wang's loss is.

Yuan! I hope my reply will be useful to you.

79 + 18 = 97 (yuan).

Simplifying this issue:

Everyone understands that the neighbors have not lost a penny.

The young man got 79 yuan and a merchandise worth 18 yuan for nothing.

So in this transaction, Boss Wang's loss is the young man's gain.

That is: Boss Wang lost 79 + 18 = 97 yuan.

If the gift is calculated at the cost of 18 yuan plus 3 yuan profit for a total of 21 yuan, it is a loss of 100 yuan.

So, mathematically speaking, it's $97. Celery buried.

But from an economic point of view, it's 100 yuan.

176 yuan. The cost of the 18 yuan gift plus the boss gave the young man 79 yuan, and the money given by the neighborhood was still 21 yuan under the skin.

The boss took out his 79 yuan and made up 100 yuan to return to the neighborhood.

18 + 79 + 79 = 176 yuan. Settle!
