Boys should take good care of themselves [entertainment circle]

After sitting down, she realized that it was inconvenient to face each other, so Su Mengyu moved the chair diagonally opposite Qin Zhenlu, opened the note in the roll, and read the questions together with him:

[One year, there was a severe drought in the fruit country, and the crops were not harvested. A well-meaning wealthy businessman passed by. He couldn't bear to see everyone starving, so he gave a bag of steamed buns to five refugees and asked them to share the steamed buns.

When the refugees brought the steamed buns back to the fruit village, it was already very late, so everyone decided to go home to rest first, and put the steamed buns in the grain pile, and then share them when they woke up tomorrow morning.

In the evening, someone quietly got up, went to the grain pile, divided the steamed bun into 5 parts, and found that there was an extra steamed bun. It happened that there was a scrawny big yellow dog sleeping next to the grain pile, so he gave the steamed bun to the big yellow dog. Then he secretly hid a portion, mixed the remaining steamed buns together, put them back into the grain pile, and quietly went back to sleep.

After a while, another person got up quietly, also divided the steamed buns into 5 parts, and found that there was one more steamed bun, so he gave it to the big yellow dog, then quietly hid one part, mixed the remaining steamed buns, and put them back into the grain pile , quietly went back to sleep.

After a while...

After a while...

All in all, 5 refugees got up and did the same thing.

After everyone got up in the morning, they distributed the steamed buns secretly, and there was an extra steamed bun, so they had to give it to the big yellow dog again.

Excuse me, how many steamed buns are there at least in this bag? ]

Although the two quickly finished reading the topic, considering the audience's acceptance, Su Mengyu read it slowly: "...after everyone got up in the morning, each of them divided the steamed buns with their own ulterior motives... Excuse me, what is this?" What is the minimum number of steamed buns? Now let’s look at this question, although the question is very long, it is actually very simple.”

[? ? ?Is this the beginning?I haven't finished reading the topic yet! 】

[Have ideas just after reading the topic?Doesn't the brain of a top student need time to think? ? ? 】

【Focus, it's actually very simple, I have a hunch what I'm going to face next (smile)】

【Only I want to say, is this big yellow dog really not going to be overwhelmed hahahaha】

[The previous one, now I know why you are not a top student yet (smile)]

【Although the topic is long, it is actually very simple... This sentence is very similar to my high school math teacher (smile)】

"Problems like this type are generally more flexible, and there must be more than one solution," Su Mengyu said while writing "swish" on the paper. Thinking of something, she suddenly turned her head and smiled at Qin Zhenlu He paused, "This is my method, please think of another one, and you can talk about it after I finish."

Su Mengyu pushed the paper in his hand over, Qin Zhenlu glanced at it, nodded, crossed out what he wrote, and wrote it again in a clean place. The idea is the same.

[What kind of fairy communication is this? You can know the other party's thinking at a glance, and immediately overturn your own thinking and start a new thinking...]

[Sorry, I don't even know one kind...]

[The two actually thought of going together, they were in sync, and they hit it off]

[He is studying hard, but you are doing cp there... Well, I can't do anything else except cp, and the two of them look beautiful too, what kind of eyelashes are paired, my God]

After the last barrage appeared, the screen suddenly became quieter, as if immersed in the handsome face of the handsome guy.

It is said that a serious man is the most handsome. At this time, Qin Zhenlu is hanging his head slightly, his thick and slender eyelashes are like crow feathers, hanging down a perfect arc in the air. From this angle, the originally handsome bridge of the nose Even more superior, the light-colored lips are slightly pursed, the fingers holding the pen are well-articulated, the wrist bones under the rolled-up cuffs are prominent, and the sitting posture is extremely upright. At this time, because of the focused expression, it reveals a confident and calm charm from the bottom of its bones .

As soon as Su Mengyu finished writing the formula, she looked up and saw such a scene, and immediately forgot what she was about to say.

Su Mengyu stared at him blankly, as if in a daze, until Qin Zhenlu raised his head and looked at him with a feeling, and then Su Mengyu looked away as if awakened.

【Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.yes huh huh? ? ? 】

[Don't talk about Xiaoyu, even I was stunned, what kind of world famous painting is this, my God]

[Double beauty crit, awsl]

[What is the screenshot?Frozen! 】

It's really disappointing, why is Qin Zhenlu stunned again?Could it be that he had to buy two posters and put them in the dormitory to practice his eyes every day?

No, it seems that he is obsessed with each other, Su Mengyu shook his head, and after the recording of this show, he doesn't know if there will be a chance to meet again in the future, so there is no need to be so troublesome.

"Ahem, let's take a look at this question." Su Mengyu collected her thoughts and turned her gaze back to the question, "Because when the steamed buns were distributed for the first time, the refugees found that there was one more bun. If you add 4 steamed buns at this time, Then it can be evenly distributed, so we can assume that the total number of steamed buns is n-4, and the number of steamed buns distributed to each person after dawn is a..."

As Su Mengyu said, the tip of the pen tapped the two calculation formulas on the paper.

[（1/5）×（4/5）×（4/5）×（4/5）×（4/5）×（4/5）×n=a

Simplification: 1024/15625×n=a]

"...Because a is an integer, the minimum n can only be 15625. Since we initially set the total number of steamed buns to be n-4, the final number of steamed buns is 15625-4=15621."

Su Mengyu put down her pen, clasped her hands under her chin, turned her head sideways, and looked at Xuan Zi'an with a smile: "How about it, do you understand?"

Xuan Zi'an, whose eyes were darkened, said, "..."

Why cue me QAQ? ? ?

[Hahahaha, Xiaoyu doesn't ask anyone, only brother Zi'an, it can be seen that brother Zi'an's imitation of scumbags has been deeply rooted in the hearts of the people]

【My little brother obviously didn't understand the expression on his face (laughing and crying)】

[Looking at other people's expressions, they should understand everything, so smart]

[Sorry for dragging everyone down, I will continue to keep it up (dog head)]

[Seeing that brother Zian didn't understand, I feel relieved (smile)]

"Okay, which step do you not understand?" Su Mengyu raised his forehead, pointed to the first sentence and asked, "Do you understand this? Do you know why n-4 is set?"

Xuan Zi'an nodded.

"Okay, then explain it again."

Xuan Zi'an: "..."

【Hahahahahaha I can't do it anymore, what kind of scene is this like dreaming back to high school?】

【Brother Zi'an doesn't know it, forget it, we don't know it, don't be ashamed (dog head)】

[Scene of large-scale school slag overturning.gif]

"Forget it, let's look at other problem-solving methods first." Su Mengyu immediately turned her head, and threw the pen in her hand on the table as if she couldn't bear to look directly at it. Come on, I'll leave the rest to you."

Qin Zhenlu smiled, first picked up the pen he had thrown away and put it in order, then looked at his paper, and said unhurriedly: "My method is also to set unknowns, but it is a little more difficult than Xiaoyu's. Suppose: there are X steamed buns at the beginning, and each person gets Y steamed buns at dawn, then the following equation can be obtained..."

[X=5A+1

4A=5B+1

4B=5C+1

4C=5D+1

4D=5E+1

4E=5Y+1]

"... After simplification, we get: 1024X=15635Y+11529. This is an indeterminate equation. According to the title, we seek the smallest integer solution. If X1 is the solution of this equation, then X1+15625 is also the solution of this equation. There is a tricky way... ..."

Qin Zhenlu said, suddenly looked at Su Mengyu, and asked with a smile: "Does Xiaoyu have any ideas?"

The process ended here, Qin Zhenlu directly wrote a result, Su Mengyu clenched his fist with his right hand, and gently rubbed his chin, this is his usual action when thinking.

"Assume Y=-1, then X=-4," Su Mengyu replied slowly, "If there are -4 steamed buns at the beginning, no matter how many times you divide them, it is in line with the meaning of the question, so add -4 15625 is the smallest integer solution, and the final answer is 15621."

"That's right, that's my way of thinking." Qin Zhen touched Su Mengyu's head with a smile, retracted his hands, put them on the table with his hands clasped, and smiled lightly, "How about it, Zi'an, do you understand?"

Xuan Zi'an, who was completely fainted: "..."

Why do you always cue me QAQ? ? ?

[What kind of fairy dialogue is this... Who am I?where am iwhat am i doing 】

【I obviously came to watch the show for fun, why can't I escape the little fairy of mathematics (smile bitterly)】

[Whether you understand it or not, just watch it (smile)]

"Why do I think, I seem to have seen this number somewhere..." Wai Zai frowned, pursed his lips and thought for a while, then clapped his hands suddenly, "Oh, I remembered! I was on Feng Xiaoxing's desktop just now seen it!"

Su Mengyu raised her eyebrows, followed Waizai back to Feng Xiaoxing's desk, and found that there were indeed a few shallow numbers written in pencil on the upper left corner of his desk, which was the answer "15621".

Xuan Zi'an's eyes widened: "Oh my god, is this the IQ of a ten-year-old kid? I'm sorry that my motherland is holding me back."

"I told you earlier that he is a genius." Su Mengyu didn't care about this. The handwriting on the table gave him new ideas. He straightened up and was about to go to the podium to check the seating chart when he saw Qin The real deer had already stood in front of a table and looked at something seriously.

Okay, got preempted again.

Su Mengyu has completely gotten used to Qin Zhenlu's muffled style of doing big things. He walked over and found a profile face of a character outlined with a pencil on the table, with a small nose, long eyelashes, and slightly grinning lips. With a small arc, it seems to be smiling, and with a few strokes, a cute boy is vividly displayed on the table.

"Whose seat is this?"

"Wang Xiaoming," Qin Zhenlu paused, and added, "Squad leader Wang Xiaoming."

Su Mengyu nodded. He knew that Qin Zhenlu had already written down the seat chart and duty schedule, so he was not surprised at the moment. He looked at the lifelike young man in front of him, narrowed his eyes slightly, and suddenly touched Qin Zhen. Lu: "Hey, who do you think Wang Xiaoming painted?"

As soon as he heard this, he knew that he had another trick, Qin Zhenlu smiled helplessly, and replied: "I guess it's him."

Sure enough, Su Mengyu shook his head, patted him on the back, and said dumbfoundedly: "You can't imagine, little brother, I guess this is Feng Xiaoxing...hehe."

Qin Zhenlu: "...?"

Is that what he meant?
