Chapter 84: Cleverly Solve the Problem of Chicken and Rabbit in the Same Cage
After understanding this, Huang Tinghui no longer hides his clumsiness.
He separated from everyone and took two or three steps forward.
"Why are you pushing me? Do you know that your push just now interrupted my train of thought?"
"I am bound to get that lantern from the county master, and you are the one who is going to ruin my life!"
The young man who was pushed by Huang Tinghui was a little angry.
I was a little unhappy because I couldn't think of an answer to the question, but now I had to take my anger out on Huang Tinghui.
"Hey, this young man!"
"I'm sorry, I won't let you have that lantern today!"
"Those who are gifted by the county master will be given to those who are talented!"
Huang Tinghui is not a doormat, he retorted sarcastically.
Although I wanted to move forward just now, I gave this person a gentle push.
But it was an unintentional move. Huang Tinghui also wanted to apologize before.
This person is so rude, how can Huang Tinghui apologize to him now?
"You...you..." the young man pointed at Huang Tinghui and said, but he quickly reacted, "You said you wanted to get that lantern?"
"Is it possible that you solved this arithmetic problem? How is it possible?"
"This arithmetic problem cannot be solved so easily!"
"You're bragging, you're bragging!"
The young master showed an expression of disbelief. He pointed at Huang Tinghui and kept saying.
"You just said you had an idea, but you don't want me to solve the problem?"
"Are you bragging? You'll know it once you see it."
Huang Tinghui stopped arguing with the person in front of him and walked forward quickly.
For a moment, everyone started talking.
"This question is a bit difficult. Has this person really solved it?"
"I think this person is talking nonsense. With so many people present, no one can solve this problem!"
"This question is difficult to solve. It is much more difficult than writing an eight-legged essay. We, the scholars, all read the books of sages. How can we have the time to solve the questions in such miscellaneous books?"
"That's right..."
Although they really wanted to win the county master's lantern, everyone was still unwilling to admit that they couldn't solve the problem, and they were inferior to others.
In the prosperous dynasty when eight-part essays were popular, not many scholars would delve into topics such as arithmetic.
After all, everyone studies to gain fame, and academics are nothing but have nothing to do with fame.
Huang Tinghui ignored everyone's comments. He stepped in front of the county master and saluted the county master.
"Master County!"
"Did you solve this problem?"
Seeing Huang Tinghui walking up, the county master asked hurriedly.
After all, if I can solve this problem, I won't be too embarrassed in front of the prefect.
This is something closely related to your career.
Seeing Huang Tinghui step forward, the county master also showed an excited expression.
"The ordinary people are not talented, so it took a lot of brain power to solve this problem!"
In front of the local parents' official, Huang Tinghui did not dare to say anything.
It is good that the county magistrate is a seventh-grade official, but in the area under his rule, his power is astonishingly great.
"Hahaha, just untie it!"
"Just untie it!" The county master stroked his beard and laughed.
"Master!"
"Bring up the pen, ink, paper and inkstone and give it to this scholar!"
The county master called out, and the master immediately brought up pen, ink, paper and inkstone.
"Sir, please use it!"
"Thank you, Master." Huang Tinghui took the pen, ink, paper and inkstone from Master's hand, and looked at the question again.
"There are pheasants and rabbits in a cage today. There are thirty-five heads on top and ninety-four legs on the bottom. What are the pheasants and rabbits?"
Translated into modern language, this sentence means: Put chickens and rabbits into the same cage. Counting from top to bottom, there will be thirty-five heads, and counting from bottom to top, there will be ninety-four legs."
"Ask how many chickens and rabbits there are each."
If placed in future generations, this would be the simplest mathematical problem.
Even if he has never learned quadratic equations, Huang Tinghui has a way to solve this problem.
Some people may say that this question is too simple, but what the ancients were exposed to is different from what modern people are exposed to.
It is not easy for them to solve this problem.
Huang Tinghui used ancient numbers to write down the entire calculation process on white paper.
In order for everyone to understand, Huang Tinghui did not even use a system of linear equations of two variables to solve the problem.
The number of rabbits is twelve, and the number of pheasants is twenty-three.
Huang Tinghui put the brush aside and took half a step back.
Everyone looked at the ink marks on the white paper and were a little stunned.
More people were speechless.
It's that simple?
Was it solved so easily?
Most of the scholars who are accustomed to reading eight-legged essays cannot even solve simple arithmetic problems.
What's more, it's a chicken-and-rabbit problem with a slight twist.
To put it bluntly, they cannot solve even some elementary school questions.
"Is that it?"
"The number of rabbits is twelve, and the number of pheasants is twenty-three."
Even the county magistrate looked at the few pens on the white paper and asked after a long while.
"exactly!"
"Master County, looking from bottom to top, there are ninety-four legs in the cage. Subtract twice of thirty-five from ninety-four, and all the remaining legs are rabbits!"
"The reason is very simple. Rabbits have four legs, while chickens have two legs!"
"Then subtract one, and all that's left will be the rabbit's feet."
"Each rabbit has two extra legs. Twice the number of rabbits is twice the result of ninety-four minus thirty-five!"
"That's twice the number of rabbits, which is the number twenty-four!"
"Then the number of rabbits can be easily determined, there are twelve."
"Subtract the number of rabbits from thirty-five to twelve, and you finally get the number of chickens."
"That's twenty-three!"
"In other words, the answer to this question is "The number of rabbits is twelve, and the number of pheasants is twenty-three."
Huang Tinghui explained it this way, and some people, including the county master and others, seemed to understand a little bit.
I see!
So Easy!
Some scholars even slapped themselves on the forehead severely, "It's so simple, why didn't I think of it!"
"I understand, I understand, although rabbits and chickens have different numbers of legs, they both have only one head!"
"I didn't expect there was such a solution, I didn't expect it!"
"Who is this man? He looks like a farmer. Is he a scholar?"
"You actually doubt whether he is a scholar. Look at his handwriting. Can an ordinary farmer write with such good handwriting?"
"This word is really good, even the word for lifting people is just like this!"
Amidst the discussions among the people around him, the county magistrate also stroked his beard and burst into laughter.
"Hahaha……"
"Hahaha……"
"Very good, very good..."
"I understand, I didn't expect this question to be solved like this!"
"Young man, you are a smart man. I hope that one day you will be on the gold medal list."
"Be an official in the same palace as me!" After saying that, the county master looked at his master, "Master, bring me the lantern!"
