Boys should take good care of themselves [entertainment circle]

At this time, everyone was in the front hall of the mechanical maintenance room, where there were mainly lockers for storing personal belongings and some odd mechanical parts.

They took off all the fake leather and threw it in the front hall, then pushed open the door of the mechanical maintenance room behind them.

What was displayed in front of everyone was a huge mechanical processing factory, with fast-moving crawlers, automated processing mode, and flow-type mechanical processing device. All the machines were working in an orderly manner.

Amidst Xuan Zi'an and Wai Zai's exclamation, Su Mengyu's gaze focused on a huge hairy object in the middle of the room.

It was a giant robot with a height of two floors. The surface of the robot was covered with remaining metal fragments. In the hollowed-out metal skeleton, many tangled colored lines erupted from the inside out. Surrounded by cold equipment and devices, it gives people an inexplicable sense of loneliness and shock.

There is no doubt that this is a broken giant machine that is struggling to repair.

"Hey, what is this?" Waizai suddenly noticed something, trotted to the foot of the giant robot, and stepped on a strange metal enclosure next to it.

"Is it a crane?" Xuan Zian tugged hard on the rope above, causing the rope fixed on the ceiling above his head to shake slightly.

He raised his head and murmured: "I'm going, we are going to go up, right?"

"This must be going up," Su Mengyu looked away from the distant top of the robot's head, pointed to the startup disk next to the crane that obviously lacked necessary equipment, and said with no expression on his face, "There must be some equipment installed here, we To be able to stand on the crane and let it carry us up."

【Oh my god, isn't it? Climb up again? 】

[Isn't Xiaoyu afraid of heights?He wants to go too? 】

[Isn't there still Teacher You and the others?It’s not necessary for everyone to go up]

[Others probably don't know that Xiaoyu is afraid of heights]

[At this time, please manually @秦真鹿]

【Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. QAQ! 】

[It’s so cruel, I dare not watch it]

[One person's blood book, I beg Brother Lu to go online soon! (｀Д*)】

"Little fish, Zi'an, come here quickly, I found this." Without hearing Su Mengyu's conversation with them, You Changyi hugged a metal box and walked around from behind the mechanical processing device not far away.

He put the metal box on the ground, pointed at the metal box with his hand, and panted while supporting his waist: "I just found this on the track. There is a title on it. Come and see it, little fish. There should be something in it." what."

Hearing You Changyi's words, Su Mengyu breathed out lightly, and looked down at the topic.

[Three computers A, B, and C are playing games together, and each of their screens has an integer greater than 0. The three computers can only see the numbers on the screens of other computers, but not their own screens. on the numbers.

But one thing the three computers all know is that the three computers are very logical computers, they can always make correct judgments, and the three computers always tell the truth.

Now, the housekeeper tells the three computers that the known conditions are: one of the numbers is the sum of the other two numbers, and then starts to ask questions to the three computers.

The butler first asked A: "Do you know the number on your display?"

A replied: "I don't know."

The butler then asked B: "Do you know what the number is on your display?"

B also replied: "I don't know."

The housekeeper then asked C, who also replied that he didn't know.

The housekeeper asked A again, and A replied: "I have 20 on my head."

What are the numbers on the screens of B and C? (various cases)]

After reading the question softly, Su Mengyu said lightly, "First of all, we can see that this is a very typical question for examining logical thinking."

Xuan Zi'an: "..."

You Changyi: "..."

Crooked Boy: "..."

So what, we (we) haven't finished reading the topic yet.

【Come, come, it's about to start again】

【Appeared!Logic freaks! 】

【Study group online】

[Specially deposit money to feel the fear of being dominated by logic [狗头]]

[Well, I'm ready to start calling NIU 666, you can start]

Su Mengyu didn't intend to stop and think, and directly began to describe her thoughts: "First of all, we can know from the title that everyone knows that their number is either the sum of the other two, or the sum of the other two. Bad. Let’s look at the first sentence first, A says he doesn’t know, so what information can we get?”

Saying that, Su Mengyu turned his attention to You Changyi and Wai Zai.

You Changyi & Wai Tsai: "..."

What happened to the sudden familiar feeling of horror?

"Uh, that," You Changyi couldn't bear it any longer, and couldn't hold back, "Xiaoyu, you can just do the questions yourself, and you don't need to worry about us."

The main reason is that they can't keep up with each other's thinking at all!So why do you want to dream of going back to school and experience the fear of being called by the teacher to answer questions when you are obviously only here to participate in a variety show? !

She didn't know that she had been pasted with a [terrorist] note by You Changyi. After hearing You Changyi's words, Su Mengyu nodded kindly.

It just so happens that he is in a hurry now, and the beautiful Lulu is still waiting for him to rescue him, but he has no time to talk about logic problems with a few people here.

Thinking in this way, Su Mengyu completely let go of herself and began to narrate.

"We can have a reverse thinking. Under what circumstances may A know the number on his display screen? There is only one possibility, that is, B is equal to C, because B minus C is equal to zero, so A will know the number on his display screen It must be B plus C, but now A says he doesn't know, so we can deduce that B must not be equal to B.

"B replied that he didn't know, what information can we infer? It is still a reverse thinking, under what circumstances might B know the number on his display screen? It is still the same as A, when A is equal to C, B can know.

"But in addition, from A's answer that he doesn't know, B can also infer that the number on his display is different from the number on C's display, so when A is equal to 2C, B can also infer that the number on his display is The number is A plus C, because at this time A minus C is equal to C, and B knows that the number on his display is different from C, so A must not be equal to C, and A must not be equal to 2C."

Having said that, Su Mengyu paused slightly, and cleared his thirsty throat, knowing that he should save the yogurt until now.

But You Changyi and Waizai had already looked at the blue sky with "who am I, where am I, and what am I doing" expressions on their faces.

As for Xuan Zi'an... Being a scumbag by nature, he has already given up treatment completely, and now his only pleasure is to gloat when You Changyi and Wai Zai are being abused.

Su Mengyu licked her dry lower lip, and continued: "C replied that he didn't know, and he could also analyze it according to the reverse thinking above. is not equal to 2A, so B minus A is not equal to A/2, that is, B is not equal to 3A/2, and A is not equal to 2B."

Speaking of this, he suddenly stretched out his hand and patted Xuan Zi'an, who was laughing foolishly. Seeing Xuan Zi'an looking over in a daze, Su Mengyu spread his hand towards him: "Please give me a pen."

"Oh, alright."

I knew he must have something in his hand.

"Thank you," Su Mengyu took the notebook and gel pen from Xuan Zi'an, pulled out the cap, flipped open a blank page, tapped the tip of the pen on the snow-white paper, "finally A answers that the number on his display is 20, so under what circumstances, A may know the number on his display?"

The slender pen barrel nimbly turned around at the fingertips, Su Mengyu held the pen, wrote a number "1" on the paper, and then drew a circle.

"One, C is equal to 2B. At this time, A knows that the number on his display cannot be C minus B equals B, but only C plus B equals 3B, but 20 cannot be divisible by 3, so this situation is ruled out.

Second, B is equal to 2C, which is similar to the first case, so it can also be ruled out.

Three, C is equal to 3B/2. At this time, A knows that the number on his display cannot be that C minus B equals B/2..."

他说着，笔尖在纸面写下几个字符：[A＝B+C＝5B/2＝20，B＝8，C＝3B/2＝12]

Then another "④" was drawn under "③".

"Fourth, C is equal to 5B/3. At this time, A knows that the number on his display screen cannot be C minus B equal to 2B/3, but only 8B/3, but the B calculated in this way is not an integer, so it can also be exclude.

"Five, C is equal to 3B. At this time, A knows that the number on his display cannot be C minus B equals 2B, but only 4B, so B equals 5 and C equals 15.

"The last situation..." At this point, Su Mengyu paused again, her beautiful eyes glanced at the faces of the people in front of her, seeing that they were all in a trance, their faces were dull, and Wan Ru was mentally retarded, so she had to lower her head and take a look. The bully sighed at the helpless gesture of the scumbag.

"Six, B is equal to 3C. At this time, A knows that the number on his display cannot be B minus C equals 2C, but only B plus C equals 4C, so we can infer that B equals 15 and C equals 5... ..."

Turning the tip of the pen lightly, he quickly circled a few numbers on the paper, closed the cap of the pen with a "boo", and threw it back into Xuan Zi'an's arms.

“最后答案有三个，B等于8、C等于12，B等于5、C等于15，以及B等于15、C等于5。”

He stood up, rubbed his numb legs, and raised his chin to those who were still dumbfounded: "812, 515, 155, try these three."
