A question that many people answer incorrectly What is a wrong question?

Includ is included, and names are included in the roster and not recorded in the roster. (A bit far-fetched...)But I think it's okay to do both, it's the habit of foreigners to speak).

It should be customary usage, and it is not wrong to b in meaning, it may be that people do not say so in this form of statement, this phenomenon is normal, as if the Chinese say"The Chinese team defeated the American team by a large margin""The Chinese team defeated the American team"It's the same, it's a habit.

Let me first define the following as a mistake:

1.There are 3 types of questions that are done incorrectly (including carelessness, unclear concepts, and logical problems, which must be strictly distinguished).

2.Won't do the question.

3.If you do it slowly, you don't finish it within the allotted time, it's your mistake.

When many students encounter a wrong question, they scan the answer and understand it, and then? And then there was no then. Such learning, IMHO, you are wasting questions and time!

Over time, you're trying the surface, but you're just repeating useless work. Wow.

When you encounter an error, the first thing you need to do is to find the cause. For example, my answer is wrong, why? Carelessness, unclear concepts, or unclear logic?

Remember, it's not enough to understand why the answer is right, the key is to figure out what you're going to think next time so that you can do it quickly and correctly.

Attention, if you can't do it, it's also a mistake! Then they look at the answer, and when the answer is understood, there is no more. Does this make sense for you to solve the problem? It doesn't make any sense at all.

The key is how to think in the future to solve such a problem. The idea behind this question is our second trick, specialization.

Principle: It is much easier to falsify than to prove (because only one counterexample needs to be found), so for multiple-choice questions, many times we can falsify three options with special examples, although we have not proved that the last option is correct, but as long as the question is not wrong, we can choose. This is an application of specialization.

This is a question in the interview, and there are three algorithms:

1.At first it was only 8 yuan, and in the end you had 11 yuan, so it was 3 yuan;

2.The first sale, the protagonist loses 8 yuan, gets a chicken, and the second sale; The protagonist gains 9 pieces and loses a chicken; The third time he buys and sells, the protagonist loses 10 yuan and gets a chicken; In the fourth sale, the protagonist gets 11 pieces and loses a chicken.

So the entire GDP (gross domestic product) generated is 8 9 10 11 38 yuan for 4 chickens.

3.There are 3 transactions in the whole event, let me take a look at which 3 are specific?

The first transaction: buy for $8, sell for $9, profit $1;

The second transaction: sell for 9 yuan, buy for 10 yuan, profit -1 yuan;

The third transaction: 10 yuan to buy, 11 yuan to sell profit 1 yuan;

The whole process: 1-1+1=1 yuan.

So the analysis shows that this person is a fool, because the last two transactions are equivalent to doing it in vain.

After testing, the enterprise believes that:

The result is: he could have earned 3 yuan directly, but after 3 transactions, the total profit became 1 yuan.

So the correct answer is: -2 yuan!

This is actually a test question specifically for the assessment of sales personnel, and the assessment is mainly based on the sales concept of being proficient in mathematical calculations.

Mathematical Calculations Section:

Let's assume that this person only has 9 yuan on him, then there is, the first transaction: -8, there is a chicken, and there is 1 yuan left;

2nd transaction: +9, no chicken, 10 yuan left;

The third transaction: -10, there are chickens, 0 yuan left;

4th transaction: +11, no chickens, 11 yuan left.

So, the answer to the math calculation is 11-9=2, earn 2 yuan.

Sales Calculation Section:

If you sell 11 yuan directly from the second transaction, the profit is 3 yuan, and the current profit is only 2 yuan, which is 1 yuan less in terms of the optimal sales strategy.

So, the real answer is: I made 1 yuan less or I could have earned 3 yuan, but I only made 2 yuan.

People who answer this question incorrectly are normal, and people who answer correctly are abnormal people.

Earned yuan.

8 buys, sells nine more 1 When he used 10 to buy, he paid 9 yuan, and finally sold 11 and earned 2 yuan.

It must have earned 2 yuan, let's say you have 10 yuan at the beginning, spend 8 yuan, leave 2 yuan, and then sell 9 yuan to have 11 yuan, and then spend 10 yuan and have 1 yuan left, and finally get back 11 yuan, and finally a total of 12 yuan in hand, 12-10=2, so simple, those who say that they have earned 3 yuan, do you use other people's money when you spend an extra dollar to buy it back?

This is a confusing question, to see if you have confidence in yourself, don't complicate a simple question, it is a simple question in itself, if you don't trust your own judgment and think that this question will not be so simple, you will fall into the trap. Originally, I made 2 yuan, let people calculate it, either lose or make more, whether it is a loss or an extra or less earn, isn't it clear if you actually demonstrate it?

8 were bought, 9 were sold, and a dollar was earned.

10 bought, 11 sold, a dollar earned.

I made a total of two dollars in two times, damn it, you actually did it wrong in such an easy question? What kind of IQ is this?

Ahaha, this question is not only an interview question, but also on the test papers of elementary school students.

Just like buying a purification cloud mask on a hazy day, it is the same reason that large companies or enterprises will have such a problem!

You're right, but it's a very old question! Don't you think.

Uh......Decide with your own way of thinking.

Landlord, what do you think it should be equal to?

I bought a chicken for 8 yuan and sold it for 9 yuan.

Didn't you earn a dollar?

I bought it back for 10 bucks.

Is it a total loss of one dollar?

11 dollars to sell to another person.

That's a dollar.

Fake silver set up all the correct answers, should get 10 3 30 points more than the actual 30 20 10 points correct answer 1 question than Feng Jianna answered 1 question more than Wang got 3 2 5 points wrong answer 10 5 2 2 answers.

The photos you took are all questions, how can you be wrong if you don't write the answers?

For convenience, let u = x. then du dx = 2x. So:

df(u)/du = e^(-u²)

Therefore, df(u) dx = df(u) du * du dxe (-u) 2x

2x * e^(-x^4)

It seems that the answer c is wrong.

Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipelines, elevators, lifting machinery, passenger cableways, large-scale amusement facilities and special motor vehicles in the field (factory) that involve life safety and are more dangerous. Among them, boilers, pressure vessels (including gas cylinders), and pressure pipelines are special pressure-bearing equipment; Elevators, lifting machinery, passenger ropeways, and large-scale amusement facilities are special mechanical and electrical equipment.

What is "Pressure Piping (Element)" in the title? Could it be that a bolt on a pressure pipe is also considered special equipment?

That's the definition in the book.
