(Damn, the title should be 'Where did that copper coin go? Sorry, I can change the content if it's wrong, but I can't change the title if it's wrong!)
In the classroom.
Sun Zifan, Yu Dongcai, and the other eight new students were not the only ones having headaches. The rest of the students were having headaches when they saw the first question.
"In a division equation, the sum of the dividend, divisor, quotient, and remainder is 75. It is known that the quotient is 8, the remainder is 2, the dividend is _ _ _, and the divisor is _ _ _."
In the previous exams, the first question was usually very simple. But this time, the first question was a linear equation with two variables, which made many people dumbfounded.
Many students were quickly calculating on the draft paper while cursing in their hearts. Although Li Zexuan had explained this linear equation with one variable to them, it would take a lot of effort to solve it. They could only pray that the following questions would not be so perverted.
Who knew that some people who had solved the first question with great difficulty would be dumbfounded when they saw the second question. It was written:
"There is a well that is seven feet deep. A snail crawls up from the bottom of the well. During the day, it climbs three feet and falls two feet at night. Can the snail climb out of the well in _ _ _ days?"
F * ck! F * ck!
Teacher is not giving us a chance to live! What kind of question is this? Why have I never seen it before? Someone is going to die! It can't be that the following questions are all perverted questions like this, right?
The students roared in their hearts, complaining that Li Zexuan's questions were too perverted.
Even Li Tai, Ke Shiqing, Zeng Ziran, Meng Wenhao, Qin Huaiyu, Iron Egg, and the others who had the best grades were deeply frowning.
Meng Wenhao's eyes were fixed on this question. If his eyes had energy, this test paper would probably be instantly penetrated by this majestic energy, right?
"Climbing three feet a day and falling two feet is equivalent to climbing one foot a day. A total of seven feet. Could it be that I have to climb for seven days? No, no, no, this question is definitely not that simple! "
Meng Wenhao's mind raced as various ideas flashed through his mind. His hands didn't stop either. He was constantly writing and drawing on the draft paper, looking for a way to solve the problem.
The rest of the students were all under great pressure. Their foreheads were dripping with sweat. The atmosphere of the entire building suddenly became extremely heavy.
Xu Hongzhi sat on the podium and looked at the group of miserable children below. He also sighed helplessly. After he received the test questions yesterday, he tried to do them. In the end, if he tried his best to do every question, he wouldn't be able to finish them in four hours.
Li Zexuan's test papers had a lot of questions. After all, the exam time was four hours (four hours). The number of questions he set was basically twice as many as the test papers in his previous life.
In the previous exam, because the questions were simple, many people did not feel that time was tight. However, it was different this time. There was not a single question on the entire exam paper that could be answered at a glance. He believed that it would not be long before the students realized that they did not have enough time.
Li Tai was also a little overwhelmed by the second novel question. However, how could he, Li Tai, be someone who would admit defeat? This question was not unsolvable. If he thought about it carefully, he would definitely be able to find the answer.
"The snail actually only moves one foot a day. Most people would definitely think that if it climbed one foot a day, it would naturally reach the mouth of the well in seven days. However, the problem is definitely not that simple. If the snail had already reached the mouth of the well, it wouldn't have continued to fall. This should be the most confusing part of this question.
Then the snail climbed four feet in the first four days. On the fifth day, it climbed three feet and directly climbed out of the well. Therefore, the snail actually climbed out of the well in five days! Perfect! I, Li Tai, am indeed the smartest, hehe! "
A proud smile appeared on Li Tai's face. He quickly wrote down the answers. However, he inadvertently glanced at the hourglass on the podium and was immediately shocked. He had used almost fifteen minutes to answer the two questions. How could this be?
Li Tai glanced at the vast sea of questions behind him. The proud look on his face disappeared. He took a deep breath and continued to immerse himself in the "battle."
"Dang, dang, dang!"
Just as all the students were still immersed in the sea of questions, the gong and drum of the first class of the Imperial College had already sounded. The students were all shocked. They did not expect time to pass so quickly. At this time, many people had not even finished the fill-in-the-blank questions. It was not difficult to imagine how crazy Li Zexuan's questions were this time!
"Oh no! It seems that some of the questions are too difficult. I have to give up! "
Iron Egg had also just finished the last fill-in-the-blank question. He estimated the time needed for the remaining questions and realized that it was not enough. He secretly made a decision.
The smart students all had similar thoughts. Easy first and difficult later. Otherwise, they would definitely not be able to get a high score.
…
Along the way, they were "defeated" many times. However, many students finally finished the last question and answer. Meng Wenhao, Li Tai, and Ke Shiqing were among them.
Li Tai wiped the sweat on his forehead and felt relieved. He began to answer the questions. A quarter of an hour later, he finally came up with an idea. He spent some time writing down the answers step by step on the test paper. Then, he was about to flip back to the questions that he hadn't answered before, but he saw that there was a big question at the back.
"F * ck, what kind of medicine did Li Zexuan take? This is too much! "
Li Tai's heart was about to be driven crazy. However, when he saw the words in the brackets behind the additional questions, his heart moved and he immediately stopped cursing.
"The total score will be increased by 20 points if the answer is correct. No points will be deducted if the answer is wrong!"
Li Tai turned back to the test paper and found that there were four or five questions that he had not answered before. The total score added up to about 10 points. Now that he had less than half an hour left, even if he used all of his time, he might not be able to answer all of the questions correctly. After all, those questions were the most difficult questions. It was better to concentrate on the last additional question. If he got it right, he would get 20 points.
Li Tai immediately made a decision and began to look at the last additional question with all his heart.
"There were three people who went to the hotel for 30 copper coins a night. Each of them paid 10 copper coins and gave the 30 copper coins to the innkeeper. Later, the innkeeper said that the discount today was only 25 copper coins. He took out 5 copper coins and ordered the innkeeper to return it to them. The innkeeper secretly hid 2 copper coins and then gave the remaining 3 copper coins to the three people. Each person received 1 copper coin, which is equivalent to each person paying 9 copper coins. This 3 multiplied by 9 equals 27 copper coins. Plus the 2 copper coins hidden by the innkeeper, it equals 29 copper coins. Please explain the reason! "
"Eh ~? This question is very reasonable, but according to this calculation, where did the 1 copper coin go? "
Li Tai was not the only one who discovered the advantage of the additional question. Sun Zifan also discovered that in the entire test paper, there were only a dozen questions that did not include Arabic numerals and operation symbols. One of them was this question, and the bonus points were very high. Sun Zifan took a fancy to this question at first glance. However, this question had already confused him. He did not know where the 1 copper coin went!
