Jiang Fan grinned and couldn't help but feel frightened when he saw Qian Rushan.
But when he thought that it was stipulated that it was an accounting problem, and the so-called accounting problem was actually arithmetic, and Qian Rushan had been amazingly talented in this area since he was a child, his uneasy mood was relieved a little.
I don’t believe that I can still be stumped by you in terms of academics!
Even if you look at the entire Zhou Dynasty, there are very few people who can compare with me in arithmetic!
As for those scholars, most of them know nothing about arithmetic!
So even if Jiang Fan can have problems with his accounts, it won't be much more difficult! Qian Rushan is very confident about this!
"The problem of accounts mainly lies in the records of income and expenditure, that is, the records of money transactions. Therefore, can I understand the problem of accounts as arithmetic?"
Jiang Fan asked with a smile.
"Of course! Arithmetic is a vast and profound subject, and many people, even if they are very knowledgeable, only have a superficial understanding of it. Accounting issues can at best be called the basis of arithmetic, but when it comes to arithmetic, there is no problem."
Qian Rushan nodded and said.
"Okay, Brother Qian, you heard me clearly, right now, there are a bunch of chickens and rabbits locked in the same cage. If you just look at the heads, there are thirty-five heads in this cage. And if you just look at the feet,
If so, there are ninety-four legs in this cage, so...how many chickens and rabbits are there in this cage?"
Jiang Fan said with a smile.
Qian Rushan's face froze, and the little confidence he had just encouraged himself and finally re-established was shaken instantly.
Su Xiaonuan and others were a little dumbfounded. They lowered their heads and picked up their fingers subconsciously. However, they soon discovered that... ten fingers were not enough...
"Sister...what kind of problem is this? Why do we put chickens and rabbits in the same cage?"
Lin Wanqing leaned next to Lin Wanru and asked softly.
"I don't understand either, but just looking at Mr. Qian's expression, I at least know that this problem should be difficult."
Lin Wanru replied softly.
"Brother Qian? How is it? Can you answer it?"
Jiang Fan looked at Qian Rushan and asked with a smile.
Qian Rushan was a little embarrassed because...he had no clue about this problem.
She said in her heart that she was lucky that she didn't say any big words just now when she regained her confidence. Otherwise... I'm afraid I would have to work hard to find a crack in the ground to get in.
What the hell is this problem! Why are chickens and rabbits kept together?
Qian Rushan looked aggrieved and looked at Jiang Fan and said: "This...if I count them one by one, I will definitely be able to solve it. But it takes too much time, so...Brother Jiang must have a simpler solution, right?"
"Of course, since there are thirty-five heads, it means that the total number of chickens and rabbits is thirty-five. We assume that the thirty-five are chickens, and the chickens have two feet, that is, seventy feet.
There are twenty-four fewer legs in the cage. Each rabbit has two more legs than each chicken, so there are a total of twelve rabbits and twenty-three chickens."
Jiang Fan said with a smile.
Qian Rushan: "..."
Lin sisters: "..."
Su Xiaonuan and others: "..."
Assume that all thirty-five are chickens?! Is this still possible?!
"How's it going? This question is about arithmetic, right? Brother Qian, you didn't answer it, then..."
Just as Jiang Fan was halfway through his words, Qian Rushan coughed twice and said with a slight blush: "Ahem, Brother Jiang, I just said that this question is too time-consuming, not that it cannot be solved. In fact, I can pick one on my fingers.
If you count them one by one, you can always count them, right?"
After saying this, Qian Rushan felt that he was so shameless.
But there was no way, he really didn't want Jiang Fan to be in a dominant position in their business.
It’s not that I have any bad intentions, it’s just that I have more confidence in my ability to run a business.
"Yes, then I'll change the question."
To Qian Rushan's expectation, Jiang Fan did not struggle with him in this regard, but seemed to be very easy to talk to.
Just why...I feel so panicked...
Qian Rushan thought silently.
"Wanru and Wanqing are walking opposite each other, ten miles apart. Wanru walks three miles every hour, and Wanqing walks two miles every hour. Xiaonuan follows Wanru, and can walk five miles every hour.
, set out together with Wanru, when he met Wanru, he turned around and walked towards Wanru, when he met Wanru, he turned around and walked towards Wanqing, and asked, when Wanru and Wanqing met, how many miles had Xiaonuan walked in total?
Jiang Fan smiled.
Qian Rushan: "..."
Lin sisters: "..."
Su Xiaonuan and his group: "..."
This is no longer a matter of counting on one's fingers, but also involves a certain amount of mathematical logic.
But obviously... no one in this world has studied the so-called arithmetic logic.
"What? Brother Qian, do you think this question cannot be calculated?"
Seeing Qian Rushan standing there with a confused look on his face, his eyes as dull as if he had lost his soul, Jiang Fan asked sincerely.
Qian Rushan felt a little embarrassed, but he would still be a little unwilling to give up.
After gritting his teeth and nodding, he forced a smile and said: "Brother Jiang... No matter this question or the previous question about a chicken and a rabbit in the same cage, it seems... they don't involve money? After all, we have to test accounts, so...
The question must be related to money, right?"
"That's it, it's easy to talk about."
Jiang Fan still had no intention of arguing.
He raised his hand and snapped his fingers, pulling everyone out of the quagmire that Su Xiaonuan had walked.
He continued with a smile: "Speaking of Wanqing, it's like staying in an inn with me. Everyone needs to pay ten cents for the room. When we checked out the next day, we gave the store clerk thirty cents. In the end, the clerk took thirty cents.
I went to give it to the shopkeeper, but the shopkeeper said that the price of the inn has been reduced these days, and the three of us only need to pay twenty-five cents, so he took out five cents and asked the waiter to return it to the three of us."
"The guy had five pennies in his hand and had some idea in his mind, so he secretly paid down two pennies. After catching up with the three of us, he returned the remaining three pennies to us. In this way, I, Wanqing and Wanru
That means each person paid nine cents, which adds up to twenty-seven cents. Adding in the two cents that the waiter left behind, it’s twenty-nine cents. So, may I ask Brother Qian, where did the remaining one cent go?"
Qian Rushan: "..."
Lin sisters: "..."
Su Xiaonuan and his group: "..."
Qian Rushan stood stunned for a moment, but his mind became more and more confused.
By the end, a look of despair appeared on his face.
He nodded dejectedly and said feebly: "Let's just follow Brother Jiang's wishes... Brother Jiang is in charge of this business. If there is any disagreement, I will listen to Brother Jiang."
