Difficulties

★You have asked some people to work for you for seven days. You should pay for it with a gold bar. This gold bar will be divided into seven parts. You must give them one piece after each day's work. If you only cut the gold strip twice, how do you score the workers?

★A train leaves Los Angeles at a rate of 15 miles per hour, heading for New York. Another train leaves New York at a speed of 20 miles per hour, heading for Los Angeles.

★You have two jars with 50 red glass balls and 50 blue glass balls respectively. Pick up a jar and take out a glass ball from it. How can we maximize the chance of winning a red ball? In this way, what is the chance of getting a red ball?

★Two odd numbers separated by one digit are called odd pairs, such as 17 and 19. It is proved that the numbers between odd pairs can always be divided by 6 (assuming that both odd numbers are greater than 6 ). It is now proved that there are no odd pairs composed of three odd numbers.

★A room has a door (closed) and three electric lights. There are three switches outside the house, respectively connected to the three lights. You can manipulate these switches at will, but once you open the door, you cannot change the switch. Determine the light for each switch.

★Suppose you have eight balls, one of which is slightly heavier, but the only way to find the ball is to place the two balls on the balance for comparison. How many times can I find the heavier ball?

★Suppose you stand in front of the mirror, raise your left hand, raise your right hand, and look at yourself in the mirror. When you raise your left hand, it seems that you are raising your right hand in the mirror. But when you look up, the mirror is also looking up, rather than looking down. Why does the image in the mirror seem to be upside down, but not upside down?

★You have 4 bottles of medicine. The weight of each pill is fixed, but one of the bottles is contaminated, the weight of the pill changes, and each pill adds a little weight. How did you suddenly determine which bottle of medicine was contaminated?

★Playing a word splitting game below will disrupt the order of all letters. You need to determine what the word is. Assume that the word to be split is composed of five letters:

1. How many possible combinations are there?

2. What if we know which five letters it is?

3. Find a solution to this problem.

★Four women are planning a bridge. They all stood on one side of the bridge and wanted them to all pass through the bridge within 17 minutes. It is evening. They only have one flashlight. Only two people can bridge the bridge simultaneously. No matter who crosses the bridge, whether it is a person or two people, must carry a flashlight. The flashlight must be transmitted and cannot be thrown. The speed of a woman crossing a bridge is different. The speed of two people must be slow.

First woman: It takes 1 minute to bridge the bridge;

Second woman: It takes 2 minutes to bridge the bridge;

Third woman: It takes 5 minutes to bridge the bridge;

Fourth woman: it takes 10 minutes to bridge the bridge.

For example, if the first woman and 4th Women bridge the bridge first, it has been 10 minutes since they passed. If 4th Women are asked to send their flashlights back, then when she reaches the other end of the bridge, it will take 20 minutes in total, and the operation will fail. How can these four women bridge the bridge within 17 minutes? What other methods are there?

★If you have a bucket of 5 kau and a bucket of 3 kau, how can you accurately produce 4 kau?

★You have a bag of sugar, red, blue, and green. Close your eyes and take out two pieces of sugar in the same color. How many times do you need to take it to ensure that two pieces of sugar are in the same color?

★If you have two buckets, one with red paint and the other with blue paint. You pull a cup from the blue paint bucket, pour it into the red paint bucket, and then pull a cup from the red paint bucket into the blue paint bucket. Which of the two buckets has a higher ratio of red and blue pigments? This is proved by arithmetic means.

Interview Questions

1. The salary difference between Mike and Todd is $21. Mike's salary is $20. What is Mike's salary? What is Todd's salary? (The answer does not contain the decimal point)

This is Microsoft's IT expert Steve? He met at an interview that was one of the most exhausting interviews he experienced. What is the purpose of applying for telephone technical support?

"At that time, I really couldn't see how this problem relates to my position," he said. "But now, I think it is indeed similar to the technical support field. In general, technical questions cannot be easily answered, sometimes you have to review your assumptions. In essence, their basic rules are the same."

In that interview, he did not get the job even though he had the answer. "I told them how I thought about this question, including how I used exclusion to remove similar answers," he said. "When the only way to calculate this question is to forget the rule that the answer does not include the decimal point, they seem very satisfied with me getting out of the trap "(the result is $20.50 and 50 cents. The answer should be the entire number .)
