Someone nearby immediately exclaimed, "Isn't this family being incredibly stingy? Two people sharing one rice bowl, how are they supposed to eat like that?"
Yang Wei was exasperated: "Why do you ask so many questions? We asked you to do problems, not to discuss whether other people's families are stingy or not."
Zu An smiled slightly. He couldn't understand why Yang Weiwei thought such a simple problem was difficult. It was something that could be solved with an equation. Could it be that people in this world couldn't do the multiplication of two-digit numbers?
He gestured casually and wrote down 60 guests.
Glug~
Yang Wei swallowed hard. How could this be? Did this guy know the answers? But I was the one who came up with these questions.
Are these questions really that easy?
He was starting to doubt his life, until he saw the other students around him looking blank, which made him feel a little better. This guy must have guessed, and he just happened to try the number 60 first. Yes, that must be it.
Zuan continues to look at the third question:
In the Mingyue City market, a rooster is worth 5 coins, a hen is worth 3 coins, and three chicks are worth 1 coin. Now, a farmer woman uses 100 coins to buy 100 chickens. How many roosters, hens, and chicks did she buy in total?
Hmm, this is interesting. There are three unknowns, but only two equations can be set up.
However, the numbers are not large to begin with, so we can exhaustively list them. Of course, we won't just blindly list them, but rather we will use a strategy. Let the numbers of the rooster, hen, and chick be x, y, and z, and simplify the equation to y = (100 - 7x) Ă· 4.
Since chickens are living animals, the number of chickens cannot be a decimal. Therefore, x, y, and z must all be integers. Thus, the number of chickens X must be an even number so that 100 - 7x is divisible by 4.
Starting with 2, you can quickly find that there are 4 roosters, 18 hens, and 78 chicks.
Seeing that he had written down the answers, Yang Wei's mind went blank. Three questions! He had already answered three questions correctly!
Even if he wanted to use the teacher's authority to say that the other party's answer was wrong, he couldn't, because in front of everyone, although these people might not be able to do it, it would be easy to verify whether it was correct by working backward from the answer, not to mention that Shang Liuyu was watching.
What's wrong with this guy? Wasn't he supposed to be a good-for-nothing? How come he can solve these problems so easily? And he's even doing it much faster than him?
Now that his opponent has answered three questions correctly, he has already lost the bet. He no longer hopes to kick his opponent out, but hopes that his opponent will not get all of them right, otherwise he will be in a difficult position.
He had never imagined this would happen, so he made the promise casually, but now the situation was making him panic.
Don't worry, the questions get harder and harder, especially the last one, which I found in an ancient rare book. Not to mention the student, even he himself couldn't solve it.
No matter how powerful this guy is, there's a limit. How could he possibly solve such an ancient problem?
However, Zu'an wrote down the answers to each question with great speed and speed, which caused gasps of surprise from the people around him. At first, everyone thought he was just lucky, just like Yang Wei. But now everyone's eyes are not blind, and they naturally understand that he is a math genius.
They had initially planned to laugh at Zu'an, since he had married the most beautiful Miss Chu and was flirting with so many of the school beauties in the list of beauties. They were all so angry that they wanted him to be kicked out of the academy.
But as things have progressed, instead of being disappointed, everyone has become increasingly excited. Watching students being expelled from the academy is nothing compared to watching teachers being expelled.
A faint smile appeared on Shang Liuyu's lips as he looked at Zu An, who was writing intently, and thought to himself that this guy was quite handsome when he was serious.
Involuntarily recalling their first encounter in the pavilion, Shang Liuyu's curiosity grew even stronger: Just how many secrets does this guy hold?
Unlike Shang Liuyu's relaxed demeanor, Yang Wei kept wiping the cold sweat from his forehead with a handkerchief. He could clearly feel everyone's gaze gradually shifting towards him, and he was genuinely starting to feel uneasy. He could only keep reassuring himself, "Don't panic, don't panic, there's no way he could possibly solve the last question."
At this moment, Zuan also stopped in front of the last question:
Two peasant women brought a total of 100 eggs to the market in Mingyue City to sell, and they earned the same amount of money. The first peasant woman said to the second, "If I had as many eggs as you, I could sell them for 15 coins." The second peasant woman said, "If I had as many eggs as you, I could only sell them for 6 and 2/3 coins." How many eggs did each of them have?
The surrounding students immediately started talking:
"Strange, they're both eggs, so why are the two farmers selling them for different prices?"
"Isn't this normal? Obviously, one of the two peasant women is pretty and the other is not so pretty. The pretty one can sell her eggs at a higher price and people will buy them, while the not-so-pretty one can only sell her eggs cheaper."
"Brother, your insight is truly brilliant!"
...
Zu An was stunned when he saw the question, and looked at Yang Wei: "Do you think this question is difficult?"
Yang Wei thought to himself, "Nonsense, why would I leave this to the last one if it weren't difficult?" But at this moment, he no longer dared to underestimate his opponent, so he could only say ambiguously, "It's not difficult for those who know how."
"It's not difficult at all." Zu An thought to himself that this was just a problem of setting up a system of equations. There were four unknowns and four equations. It was just that the calculation process might be a little complicated.
Yang Wei was furious, thinking to himself, "I was just being polite, and you've taken advantage of my kindness? Let's see if you can pull it off!"
