"A-Ning, don't tell me the answer yet, let me guess!"

Hearing this question, Xiao Yuxuan began to think.

He has been smart since he was a child, and he is often praised by his father for the Xiao family Qilin, and in the school, even if he has much less time to study than others, he often ranks first.

Two gatekeepers, one telling the truth and the other telling a lie, can only ask one question to judge whether they are alive or dead.

He brought himself in, and if he found a random gatekeeper and asked, do you know which way to survive?

Then, the gatekeeper who tells the truth must say the way to life, and conversely, the gatekeeper who tells the lie must say the way to death.

Since the identity of the gatekeeper cannot be determined, then it is impossible to judge the way of life and death.

At the end of the day, it's the questions asked that matter.

Since the identity of the gatekeeper cannot be determined, a question must be asked, and the answer can be found without judging the identity of the gatekeeper.

Xiao Yuxuan quickly figured out the crux of the matter.

Seeing Xiao Yuxuan thinking.

Zhang Xuewen was very disdainful, he had been meditating for so many days, but there was no result, this person wanted to find the answer in just a few minutes, it was a dream.

He is the only child in Qinghe Village!

Xiao Yuxuan is still thinking, assuming that there is no need to judge the identity of the gatekeeper, there is only one possibility, that is, this question connects the two gatekeepers.

Anyway, one of the gatekeepers tells the truth and the other tells lies.

The answer is on the horizon.

Xiao Yuxuan smiled and said, "I already know the answer, this person can ask a random gatekeeper to ask a question, "You said that another gatekeeper will point out which way to live?" "This person who goes the opposite way is the way of life!"

Zhang Xuewen glared at Xiao Yuxuan, thought about it carefully, and found that Xiao Yuxuan's answer was correct.

Because if this person asks the gatekeeper who tells the truth, the gatekeeper must know that the gatekeeper who tells lies refers to the dead end, so taking the opposite path is the way of life.

If the person asks the gatekeeper who tells a lie, and the gatekeeper who tells the lie must also point out the opposite way of life and death pointed out by the truth-telling gatekeeper, then this person takes the opposite path, that is, the way of life.

Chu Ning clapped his hands and said with a smile: "Awesome, my little Xuanxuan!" ”

This question was also something she had unintentionally seen on the Internet in her previous life, anyway, she couldn't solve the correct answer at the time, and it dawned on her after reading the answer.

Zhang Xuewen was hit hard and pointed at Chu Ning: "You guys colluded, right?" ”

He couldn't accept that his IQ was so brutally crushed.

"Collusion good routine you? Don't be embarrassed, sister doesn't have this idle time! Chu Ning waved his hand, too lazy to entangle, and immediately said: "The second question that my sister gave you, there is a pasture that can be eaten by ten sheep for twenty days, and fifteen sheep for ten days, so how many days can it be eaten by twenty-five sheep?" ”

"Right!"

This time, Zhang Xuewen red-eyed, pointed at Xiao Yuxuan, and said loudly: "That's right, this time, you come again, the problem last time was a fluke for you, this time it's an arithmetic problem, it's useless for you to guess, you do it again, I don't believe you can calculate it!" ”

He pondered for a long time, and he didn't know how much the paper had wasted, and he didn't figure out the right answer.

Xiao Yuxuan smiled: "This question is even simpler!" ”

"The pasture grass, the daily grass, and the grass grazing of each cow are the same......"

"Wait...... Growing grass every day, growing grass every day? Zhang Xuewen asked thoughtlessly, patted his thigh, and looked distressed: "Yes, grass grows every day, grass grows every day, why did I forget this."

Xiao Yuxuan was upright and continued: "The consumption of fifteen sheep eating grass every day to get rid of the daily grass is about twice that of ten sheep eating grass every day to remove the daily grass, so the amount of grass growing every day is equal to the daily grass consumption of five sheep,...... Then, the daily net consumption is the amount of grass eaten by ten sheep, a total of ten days, the original amount of grass is the consumption of hundreds of sheep eating grass, and now the answer is out, twenty-five sheep can eat up all the grass for five days! ”

"Correct!"

Chu Ning clapped his hands, "Master Xiao, are these children in Qinghe Village blessed?" ”

You must know that the ancients didn't understand any equations, but Xiao Yuxuan was stunned and quickly solved the problem with a clear mind.

Zhang Xuewen was surprised: "He is the master?" ”

"That's right, he's the master of Qinghe Village!" Chu Ning said.

Zhang Xuewen was completely devastated, he was a master at such a young age, which means that he has the fame of Xiucai.

He remembered that Liu Fuzi also said today that in two years, he would be able to take the Xiucai exam, and this person would have a reputation for Xiucai.

I can't tell whether it is envy or jealousy, Zhang Xuewen feels that there is a fire in his heart, and the whole soul of the person is burned.
