Fame starts with the radio

Chapter 54 Math Problem

【Question 001 has been completed, please answer question 188 first! 】

For the last assessment, the radio station relaxed the restrictions. During the examination, the other candidates who were eliminated could watch it on the big screen. Seeing the number 001, all the anchors were excited.

"Brother Long now has 855 points, and the kid on No. 188 has 850 points. The difference between the two is 5 points."

"What is the origin of this kid, he can get such a high score! It seems that he hardly lost points in the previous rounds."

"It doesn't matter, this round he will be dead no matter what! Brother Long is a top student in the mathematics department, and this round will definitely solve math problems. This is simply the death spot of our broadcasting major..."

"Yes, even if this kid asks a very difficult question, if the two of them are at most tied, Brother Long will still win by 5 points more than him!"

On the big screen, the game video is on the right, and the top ten anchor points are on the left.

Currently ranked No.1, it is Long Fei!
Integral 855 points!
No.2!
Number 188!Integral 850 points!
No.3 points plummeted, only 580 points!
To the 10th place, the points are only 230 points!
It can be seen how cruel the game is! ! !
Just when everyone was discussing, Long Fei's question appeared!

[Boss Wang sells shoes. A pair of shoes buys 20 yuan and sells them for 30 yuan.A customer came to buy shoes and gave Zhang 50. Boss Wang had no change, so he asked a neighbor for 50 yuan.Afterwards, the neighbor found out that the money was fake, and Boss Wang compensated the neighbor another 50.May I ask how much money Boss Wang lost in total?]

Seeing the title, these people laughed again!

"I guessed it right! It's really a math problem!"

"Wow, it looks very brain-inducing, real money 20...sell 30...and give a fake money 50...and then change it to real money 50, I feel that my brain is not enough..."

"No. 188 is a tragedy this time, unless he has learned Mathematical Olympiad..."

……

Just when these people were badmouthing Ling Yun, unexpectedly, in just 1 minute, Ling Yun's answer came out.

What shocked them even more was that Ling Yun not only gave the answer, but also used three solutions.

Solution 1:

The money Boss Wang paid: 20 yuan of capital + 50 yuan for compensation to neighbors = 70 yuan

The money Boss Wang got: 20 yuan (real money) left after giving 30 yuan to the customer

So: Boss Wang lost money: 70-30=40 yuan

Solution 2:

Assuming that Boss Wang has no change, he will lend 20 yuan to the customer from his neighbor, and ignore the 50 yuan fake money.

因此等于：鞋子20元白送了，还要还邻居20元，一共亏掉20+20＝40元

Solution 3
Only calculate the loss of Boss Wang: the cost of the shoes is 20 yuan, and 20 yuan is returned to the customer, so the total loss is 20+20=40 yuan. (With the neighbors, first exchange the fake for the real, and then exchange the real for the fake, which is equivalent to no exchange)

Note: If the shoes are calculated at cost price, the answer is 40 yuan, and if the shoes are calculated at sales price, the answer is 50 yuan.

Seeing this answer, all the anchors frowned and thought, and then they were all surprised!
"I, Cao, did you really figure it out?"

"This question is too brain-intensive to figure it out, but I feel that number 188 is not easy. Three algorithms are given in one minute. I'm afraid this guy is not a part-time Olympiad tutoring class?"

"Look at Brother Long's expression, I guess the guy number 188 is right!"

……

It can be seen from the occasional switching scenes on the big screen that Long Fei's astonishment at the moment is all written on his face.

In addition to surprise, there is also a trace of regret...

He regretted that his question was a bit hasty.

He originally planned to rely on his strong mathematical advantages to kill his opponents in this round of competition. He thought that this group of anchors were not particularly professional in mathematics, so he just asked a difficult elementary school Olympiad question. , he can use this to laugh at the other party.

Unexpectedly, the face was slapped, slapped, slapped...

But the other party didn't give him more time to be amazed, because...

The other party's exam questions...

Also coming! ! !
The screen flashed, and the other anchors froze...

"What is this?"

"Is this also called a question?"

"I don't understand... I really don't understand..."

……

Seeing the topic, Long Fei was also stunned...

The on-screen questions are so simple that they can drive you crazy! ! !

Only one sentence!

[Please prove: 1+1=2! 】

Watched for 5 minute!

Long Fei's face changed from yellow to red, then from red to white, and finally to black again...

If it was a pressure cooker, he would blow himself up!

He has always been called the Prince of Mathematics by the people around him, but this time, he was so humiliated!
Is this supposed to be a joke to me?
Move the mouse with his atmosphere!

"Look! Brother Long is going to apply for a human referee to arbitrate!"

I don't know who yelled, but at this moment, Long Fei turned the mouse, moved it to the left, and clicked the [Request Voice Call] button.

This button only appears in more flexible question types, so that candidates can ask the question maker some supplementary information about the test questions by voice.

But there is a prerequisite that whether the questioner agrees to answer the question is entirely voluntary! ! !

beep……

There was only one sound, and Ling Yun connected the voice.

Then heard the sound of Long Fei gnashing his teeth from the microphone.

"I want to know what is the point of proving that 1+1=2?"

"Because...if you don't prove it, how do you know that 1+1=2?"

In a word, Long Fei was speechless again, yes, if this equation is not proved to be true, then why is this equation true?

Mathematics has always been a very rigorous subject, and Long Fei does not allow everyone to question mathematics.

But now...

Do you want to prove that 1+1=2?
how to prove?

He was a little panicked...

panicked group...
