If you can solve the following five questions, you must be a man of god (which is definitely impossible)

Problem description:

If you can solve the following five questions, you must be a man of god (of course impossible); If you can write four questions, your intelligence is the most incredible person in the world; If you can make three questions, your intelligence can complete any logical reasoning problem; If you can answer 2 questions correctly, your intelligence can get an annual salary of 3 million; If you can do 1, your intelligence is much stronger than the average person; A question is not done right, and the intelligence is normal; If you can't understand the topic, it means you have a mental problem! ! ! The president of Microsoft only asked three questions! (premise: the answer is my own, not from other places or discussed)

1, 6 people cross the bridge at night with only one flashlight, and the crossing time is 20min, 15min, 10min, 5min, 2min and 1min respectively. The following two conditions must be met: (1), only two people can pass at a time; (2) You need a flashlight every time you cross the bridge. (Note: it takes 20 minutes to cross the bridge, and it takes 20 minutes for people with 1 minute to cross the bridge together)! Excuse me: how can they cross the bridge to minimize the crossing time? How long will it take? (Hint: The required time should never exceed 42 minutes)

There are two ropes with uneven cross section and a lighter. After unilateral ignition, each rope can burn for one hour. There is no clock now. Excuse me: how do you know that it has just passed 45min minutes by burning the rope?

There are two bottles with strange shapes, but they can just hold 8 ounces of wine, and there is a wine glass, which can just hold 3 ounces of wine. Now the bottle is full of wine and the cup is empty. Excuse me: how can these two bottles of wine *** 16 be distributed equally to four people, and each person just drinks four taels? (Note: You cannot use any other tools)

4. Divide the money among pirates: Five pirates robbed 100 gold, and now each pirate will propose a plan to divide the money. The order in which the plans are put forward will be decided by drawing lots. The pirate who draws "1" will be the first to propose the plan of sharing money, and so on, and the pirate who draws "5" will be the last to propose the plan of sharing money! If: (1), the proposal put forward by the pirates is not approved by more than half of the pirates (including themselves), they will be sent to the sea to feed the fish, and then the next pirate will propose a plan to share the gold, and so on! ! (2), assuming that every pirate has enough wisdom, super logical reasoning ability and enough reason! ! ! I would like to ask: What is the best plan for pirates who smoke "1", so as to get the most gold and maximize their benefits and not be sent to the sea to feed fish?

5. There are 12 glass beads, but there are 1 1 glass beads with the same quality, but the quality of 1 glass beads is different from other 1 1 glass beads, but I don't know whether it is heavy or light! There is only one scale now, and there is no scale. Excuse me: how can I find this abnormal glass bead only after using the balance for three times?

Analysis:

1. I took 1m and 2m first, and then 1m brought the flashlight back, which took 3 minutes.

Let 5m and 10m pass, and 2m bring back the flashlight. It took 12 minutes.

Then 1m and 2m went again, and 1m brought the flashlight back and used it for another 3 minutes.

Then 20m and 15m walked over and asked 2m to bring back the flashlight, which took 22 minutes.

Finally 1m and 2m passed, and another 2 minutes passed.

A * * * took 3+ 12+3+22+2 = 42min.

If both ends of a rope are lit at the same time, it will burn for half an hour.

If the other one is folded in half, it will take half an hour to burn. If the two ends are lit together, it should take fifteen minutes to burn. So it takes 30+ 15 exactly 45 minutes to burn the first one and then the second one.

Three. 1. Take two copies of each bottle for two people to drink.

2. Put the remaining two pairs into a wine glass, draw the scale of two pairs, and then fill the glass with another bottle of wine for one person to drink. Now three people have each drunk three taels, one bottle has seven taels left, and one empty bottle.

3. Then pour out seven taels and let one drink three taels. Now four people drink three taels each, and there are four taels left in the bottle.

Fill the bottle with four or two cups, then empty the bottle and mark the remaining one or two cups as one cup, so that everyone can make up one or two glasses of wine.

Four.

There are many variants of this problem,

The first case: if the first person is not stupid, he will definitely not ask for equal share, because if everyone gets 20 gold coins, the other four people will find an excuse to kill him, so if he gets less gold coins than the other four people, he will not be killed, and the remaining gold coins must be shared equally by the other four people, so calculate how much he can get at least 100 gold coins, and the rest can be divided equally by 4. -1 No, two can't, three can't. By analogy, he can get 4, 8, 12, 16 with less than 20 gold coins. If he wants to save his life, he'd better divide it into four gold coins, and each of the other four people will get 24 gold coins.

In the second case, no matter how the first person gets out of Fang An, others don't agree and kill him. The second person is also killed, and the third person can choose 4 to divide the gold coins equally, kill 5, or choose 5 to divide the gold coins equally and kill 4, because in the case of three people, only one person can pass 2- 1.

Haha, maybe the last two people killed each other and both died. 100 gold coin is yours, haha.

Five.

1. First of all, 6 on one side.
