Ask a lot of intellectual questions

123 Three people went shopping. They bought one thing altogether, 30 yuan. They each paid 10 yuan for shopping, but there was a discount that day. As long as 25 yuan remains, 5 yuan remains. 1 said: I will give you a refund of 1 yuan, and we will buy sugar for the rest. But the problem came out. One person returned 1 yuan, which is equivalent to everyone's 9 yuan, 3927, plus the rest of 2 yuan, only 29 yuan. What about the other 1 yuan?

I even gave you the answer.

You let the workers work for you for 7 days, and the workers' reward is a gold bar. Gold bars are divided into seven consecutive sections. At the end of each day, you must give them some gold bars. If you are only allowed to break the gold bars twice, how can you pay the workers?

1, if it is broken twice, it will be divided into three parts. I divided the gold bars into 1/7, 2/7 and 4/7. In this way, I can give it to him on 1 that day1/7; The next day, I gave him 2/7 to get back1/7; On the third day, I will give him 1/7, plus the original 2/7 is 3/7; On the fourth day, I gave him 4/7 gold bars and asked him to find out 1/7 and 2/7 gold bars. On the fifth day, give him1/7; The sixth day is the same as the second day; 1/7 restored him on the 7th day.

2: Now Xiaoming's family has crossed the bridge. It's dark when crossing the bridge, so there must be a light.

15 pirate gold coin:

In the United States, it is said that the average annual salary of people who can answer this question within 20 minutes is more than 80,000 dollars.

After five pirates robbed 100 gold coins, they discussed how to distribute them fairly. Their agreed distribution principle is: (1) draw lots to determine everyone's distribution sequence number (1, 2, 3, 4, 5); (2) Pirates who draw lots. 1 Propose a distribution plan, and then five people will vote. If the plan is approved by more than half of the people, it will be distributed according to his plan, otherwise it will be thrown into the sea to feed sharks. (3) If not. 1 cast into the sea, No.2 puts forward the distribution plan, and then there are 4 people left to vote, if and only if it exceeds. 4 and so on. Assuming that every pirate is extremely intelligent and rational, they can make strict logical reasoning and rationally judge their own gains and losses, that is, they can get the most gold coins on the premise of saving their lives. At the same time, assuming that the results of each round of voting can be implemented smoothly, what distribution scheme should the pirates who have drawn 1 put forward to avoid being thrown into the sea and get more gold coins?

15 problem-solving ideas 1:

Let's talk about Pirate No.5 first, because he is the safest and has no risk of being thrown into the sea, so his strategy is also the simplest, that is, if all the people in front are dead, then he can get 100 gold coins by himself. Next, look at No.4, and his chances of survival depend entirely on the existence of others in front, because if all the pirates from 1 to No.3 feed sharks, then No.5 will definitely vote against the distribution plan proposed by No.4 to let No.4 feed sharks keep all the gold coins. Even if No.4 pleases No.5 to save his life and puts forward a plan like (0, 100) to let No.5 monopolize the gold coins, No.5 may think it is dangerous to keep No.4 and vote against it, so that he can feed the sharks. Therefore, rational No.4 should not take such a risk and pin his hope of survival on the random selection of No.5. Only by supporting No.3 can he absolutely guarantee his life. Look at number three. After the above logical reasoning, he will put forward such a distribution scheme (100,0,0), because he knows that No.4 will unconditionally support him and vote for him, so adding his own 1 vote will make him safely get100 gold coins. But player 2 also knows the allocation scheme of player 3 through reasoning, so he will propose a scheme of (98,0, 1, 1). Because this scheme is relative to the distribution scheme of No.3, No.4 and No.5 can get at least 1 gold coins. Rational No.4 and No.5 will naturally think that this plan is more beneficial to them, support No.2, and don't want No.2 to go out, so No.3 will be allocated. So number two can get 98 gold coins with a fart. Unfortunately, One Pirate 1 is not a fuel-efficient lamp. After some reasoning, he also understands the distribution scheme of No.2. The strategy he will take is to give up No.2 and give No.3 1 gold coins, and at the same time give No.4 or No.5 2 gold coins, that is, to propose (97,0, 1 2,0) or (97,0). Because the distribution scheme of 1 can get more benefits for No.3 and No.4 or No.5 than No.2, then they will vote for 1, plus 1' s own 1 ticket, and 97 gold coins can easily fall into the pocket of 1.

16 card guessing problem

Mr. S, Mr. P and Mr. Q know that there are 16 playing cards in the desk drawer: hearts A and Q, 4 spades J, 8, 4, 2, 7, 3 flowers K, Q, 5, 4 and 6 diamonds A and 5. Professor John chooses a card from 16 card, tells Mr. P the number of points in this card, and tells Mr. Q the color of this card. At this time, Professor John asked Mr. P and Mr. Q: Can you infer what this card is from the known points or colors? So, Mr. S heard the following conversation: Mr. P: I don't know this card. Mr q: I know you don't know this card. Sir: Now I know this card. Mr. Q: I know that, too. After listening to the above conversation, Mr. S thought about it and correctly deduced what this card was. Excuse me: What kind of card is this?

16 solution idea:

From the first sentence, "Mr. P: I don't know this card." It can be seen that this card must have two or more suits, that is, it may be A, Q, 4 and 5. If this card has only one suit, Mr. P knows the number of points in this card, and Mr. P must know this card. From the second sentence, "Mr. Q: I know you don't know this card." It can be seen that the points of this suit card can only include A, Q, 4 and 5, and only hearts and diamonds meet this condition. Mr. Q knows the color of this card. Only the colors of hearts and diamonds include A, Q, 4 and 5 can Mr. Q make this assertion. From the third sentence, "Mr. P: Now I know this card." It can be seen that Mr. P passed "Mr. Q: I know you don't know this card." Judging that the suit is hearts and diamonds, Mr. P knows the number of points in this card, and Mr. P knows this card. Accordingly, excluding A, this card may be Q, 4, 5. If the number of points in this card is A, Mr. P still can't judge. From the fourth sentence, "Mr. Q: I know." Visible colors can only be squares. If it is a heart, Mr. Q can't judge whether it is Q or 4 after excluding A. To sum up, this card is 5 diamonds.

Reference answer:

This card is five diamonds.

17 (rope burning problem) rope burning problem

It takes 1 hour to burn an uneven rope from beginning to end. Now several ropes are made of the same material. How to time an hour and fifteen minutes by burning rope?

17 solution idea:

Burn a rope like this from beginning to end 1 hour. So it takes half an hour to burn the head and tail at the same time. Burn two such ropes at the same time, one at each end and one at both ends; When the rope at both ends is burned out, it takes * * * half an hour, and the rope at one end continues to burn for half an hour; If the other end of the burned rope is also ignited at this time, it only takes fifteen minutes.

Reference answer:

Burn two such ropes at the same time, one at each end and one at both ends; When one is burned out, take the other one out for later use. Labeled rope 2. Find another rope like this and mark it as rope 1. Burning rope at one end 1 required 1 hour, and burning rope at both ends 15 minutes. This method can time 1 hour 15 minutes.

18 table tennis problem

Suppose there are 100 ping-pong balls arranged together, and two people take turns to put the balls in their pockets. The winner is the person who can get the100th table tennis. The condition is: the person who holds the ball must take at least 1 at a time and not more than 5 at most. Q: If you are the first person to take the ball, how many should you take? How can I take it in the future to ensure that you can get the100th table tennis?

18 solution idea:

1, we might as well do the reverse reasoning. If there are only six table tennis balls left, let the other side take the ball first, and you will definitely get the sixth table tennis ball. The reason is: he takes 1 and you take 5; If he takes two, you take four; If he takes three, you take three; If he takes four, you take two; If he gets five, you get 1. 2. We divide 100 ping-pong balls into groups from back to front, with 6 ping-pong balls as a group. 100 is not divisible by 6, so it is divided into 17 groups; 1 group 4,1group 6. 3. In this way, four players in the 1 group will be completed first, and then each team in the 16 group will let the other team take the ball first, and the rest will be completed by themselves. In this way, you can get the last place in the 16 group, that is, the100th table tennis.

Reference answer:

Take four first, he takes n, you take 6-n, and so on, to ensure that you can get the100th table tennis.

19 drinking soda)

The problem of drinking soda water

1 yuan a bottle of soda, drink two empty bottles for a bottle of soda, Q: You have 20 yuan money, how many bottles of soda can you drink at most?

19 solution ideas 1:

At first, 20 bottles were fine, and then 10 bottles were fine. Then divide the five bottles into four bottles and 1 bottle, first change the four empty bottles into two bottles, and then change the two bottles into 1 bottle after drinking. At this time, the number of empty bottles left on hand after drinking is 2, and these 2 bottles are replaced by 1 bottle to continue drinking. You can give the bottle back to others after drinking the exchanged bottle, so the most soda you can drink is: 20+10+5+2+1+1= 40.

Problem solving ideas 2:

Look at 1 yuan first. How many bottles of soda can you drink at most? Drink 1 bottle and 1 empty bottle, borrow 1 empty bottle from the merchant, and exchange two bottles for 1 bottle to continue drinking. After drinking, return these empty bottles of 1 to the merchants. That is, 1 yuan can drink up to 2 bottles of soda. Of course, 20 yuan can drink up to 40 bottles of soda.

Ideas to solve the problem 3:

Two empty bottles for one soda, we know that pure soda is only worth 50 cents. Of course, 20 yuan can drink up to 40 bottles of pure soda. Of course, you can drink 2N bottles of soda at most for N yuan.

Reference answer:

40 bottles

22. A group of people have a dance, and everyone is wearing a hat. There are only two kinds of hats, black and white, and there is at least one kind of black. Everyone can see the color of other people's hats, but not their own. The host first shows you what hats others are wearing, and then turns off the lights. If someone thinks he is wearing a black hat, he will slap himself in the face. The first time I turned off the lights, there was no sound. So I turned on the light again and everyone watched it again. When I turned off the light, it was still silent. I didn't get a slap in the face until I turned off the light for the third time. How many people are wearing black hats?

There are three people wearing black hats. Suppose there are n people wearing black. When N= 1, the person wearing black can determine that he is black when he sees that everyone else is white. So when the lights are turned off for the first time, there should be a sound. It can be concluded that N> 1. For everyone who wears black, he thinks he is white when he sees the black hat of N- 1. But after waiting for N- 1 times and no one hits himself, every black person can know that he is black. So when the lights were turned off for the nth time, n people hit themselves.
