In his spare time, Miao Chengping also discusses some mathematical problems.

Zhang Wenqin's problem, although they spend a little time, can be calculated, and the bit is by no means a problem that can be calculated simply by thinking about it.

Therefore, they also want to know how Lu Dashi calculated it.

Seeing everyone's expectant eyes, Miao Yufeng was even more proud, as if the person who answered the question just now was himself.

Miao Yufeng pushed Lu Dashi and deliberately said loudly, "Brother Lu, since they don't understand, then you can teach them and let them have a long experience." ”

Hearing Miao Yufeng's words, Zhang Wenqin sneered in her heart, she had already decided that Lu Dashi would never be able to say the steps to answer, and said deliberately.

"That's right, Lu Zhutou, you hurry up and say it, and let us have a long experience!"

Although Zhang Wenqin said it well, Lu Dashi knew very well where she wanted to gain knowledge, and she clearly wanted to make herself ugly.

This problem, if there is no equation, it is almost impossible for Lu Dashi to solve it so quickly.

The most important thing is that with a simple equation, Lu Dashi really won't use stupid methods to solve the problem.

Lu Dashi thought about it, and then said with a smile.

"Actually, as long as you can figure out the key to this question, you will naturally be able to solve it very easily."

Speaking of this, Lu Dashi's tone paused, he picked up the teacup on the table, put it in front of him, and then continued, "This problem, the biggest difficulty, is that we only know how much silver is left, so we can assume it." ”

Speaking of this, Lu Dashi looked at the tea in the cup with his hand, wrote an equation on the table, and then said with a smile.

"Let's assume that the number of people in the room is X, and we can make this equation."

Speaking of this, Lu Dashi's tone paused before continuing, "As long as there is this equation, it is easy to figure out this problem. ”

Zhang Wenqin got closer, only tilted her head slightly, and saw the equation written by Lu Dashi on the table, and was stunned, no matter how high her knowledge was, she didn't understand what it meant.

Miao Chengping, Lu Jiansheng and others had already left their seats and came behind Lu Dashi, and after seeing the equation written by Lu Dashi, they were also confused.

After Zhang Wenqin came to his senses, he suddenly sneered, "Lu Zhutou, I doubt that you deliberately wrote something that we don't understand to perfunctory us!" ”

Speaking of this, Zhang Wenqin's tone paused, and then continued, "And the question just now, you already know the answer, but you don't know the steps to answer, so you scribbled it and wanted to fool the past, right?" ”

Lu Dashi actually didn't want to do this, and he couldn't help it.

If you want to explain the equation to them, you can't explain it in a moment.

Lu Dashi thought for a while, then turned his head to look at Zhang Wenqin, and said with a smile, "If Miss Zhang doesn't believe it, you can say another question, and I can also solve it for you." ”

Although Lu Dashi looked confident, Zhang Wenqin would never believe it, and in addition, he didn't believe that Lu Dashi would happen to hear about another problem in addition to this question.

Thinking of this, Zhang Wenqin's two delicate eyebrows furrowed slightly, and he began to think in his heart about what kind of problem to give Lu Dashi.

After thinking for a while, Zhang Wenqin's eyes suddenly lit up, and she finally remembered a difficult problem, and she was sure that this problem would definitely be able to stump Lu Dashi.

Zhang Wenqin raised his head and looked at Lu Dashi, and said slowly, "Since Lu Zhutou is so confident, then I will give you another question, if you answer correctly, it proves that what you said is true." ”

When Lu Dashi heard this, he nodded indifferently, an ancient person who was not even at the level of junior high school, if he wanted to stump a highly educated person, it was impossible to think about it!

Seeing Lu Dashi's confident appearance, Zhang Wenqin was stunned for a moment, and after being stunned, he said slowly.

"In a temple, there are a total of 100 monks, the big monk eats 4 each, and the small monk eats 1 for 4 people.

They ate a total of 100 steamed buns at each meal. ”

Speaking of this, Zhang Wenqin's eyes were firmly fixed on Lu Dashi, and then he asked word by word.

"Lu Zhutou, tell me, how many great monks are there in this temple? How many little monks, and how many steamed buns do they eat? ”

Hearing Zhang Wenqin's question, Lu Dashi only thought about it slightly, and immediately dipped the tea in the cup and wrote down an equation on the table.

With this equation, Lu Dashi calculated slightly in his heart, then raised his head to look at Zhang Wenqin and said with a smile.

"Miss Zhang, if I'm not mistaken, there are a total of 20 big monks and 80 small monks in this temple.

Miss Zhang, I don't know if I'm right? ”

Seeing that Lu Dashi said the answer so quickly, Zhang Wenqin looked at the equation on the table in disbelief, then looked at Lu Dashi, and began to calculate silently in his heart, whether the answer Lu Dashi said was right or not.

Zhang Wenqin's teacher only said this question recently, so Zhang Wenqin didn't know the answer.

Just when Zhang Wenqin was thinking silently in his heart, Miao Chengping, who was standing behind Lu Dashi, clapped his hands violently and said with a smile.

"Lu Zhutou, I really didn't expect you to be so powerful, such a problem, you can figure it out so quickly!"

After hearing Miao Chengping's words, Zhang Wenqin was taken aback, although she hadn't figured it out yet, she also knew that the answer Lu Dashi said was correct.

Miao Chengping is well-known among these young people, and if he is right, he will never be wrong.

Zhang Wenqin looked at Lu Dashi in surprise, and couldn't understand that such a complex problem, Lu Dashi could calculate it in such a short time with such a simple formula.

Miao Chengping smiled and patted Lu Dashi's shoulder, "I really didn't expect it, Lu Zhutou, your arithmetic is so good!" ”

Lu Dashi hurriedly waved his hand, "Where, where, these are just small skills of carving insects, and compared with Miao Gongzi's talents, they can't be put on the table." ”

Hearing Lu Dashi say this, Miao Chengping was also a little proud in his heart.

Scholars in this era are almost all liberal arts students, although they are also involved in science, but they are not profound, and the most important thing is that they are not used in the exam, so few people study seriously.

Miao Chengping smiled and nodded, "Lu Zhutou, no matter what, you are also a smart person, no wonder you can solve so many big cases, it can be regarded as amazing!" ”

Seeing Miao Chengping praising Lu Dashi so much, Zhang Wenqin was even more surprised in her heart, she never expected that the question that she thought was difficult in the eyes of the teacher would be solved so easily by Lu Dashi, could it be that Lu Dashi is stronger than her teacher?
