The person tested the following topics:
We all know that water can support the fish in the water, then answer this question: If we have a bucket only half a bucket, put the bucket in the balance, the water and buckets just 45 kg. Then put a 5 kg of fish into the bucket, what is the total weight?
Most adults will say 45 kg plus 5 kg is 50 kg. The person who presided over this time may ask: "How will this be correct? You know that water will support the fish." Temmer wrote: "If the person being tested continuously changes the answer, then Say that I think the answer should be 50 kg but is not sure, then it is divided into zero. "Only in the use of logic to defend the correct answer for his own, it will defeat twice" challenge ", the answer will be considered correct of.
Microsoft is not happy to disclose the disclosure of the interview problem, but it is very helpless. In the early 1990s, ChrisSells was interviewed at the Developmentor. At the end of the interview, the founder of a company said: "Okay, you are hired. But ask you a Microsoft company asking questions during the interview - why the sewer lid is circular? "Celes replied:" No problem, if you answer this question first, I will answer your question - Why is the fireman's strap is red? "The company founded the dumb. This experience prompted Serbs to start collecting Microsoft's interview issues. In 1996, he created a website and started to post himself on the Internet.
50 people in the village, each has a dog. There is a disease in these 50 dogs (this disease will not be infected). So people will find out the dog. Everyone can observe other 49 dogs to determine if they are sick, only their dogs can't see. The results obtained after observation must not be exchanged, and the owner of the disease dog cannot be notified. Once the owner is, the owner is a sick dog, it is to shoot his dog, and everyone only has the right to shoot her own dog, there is no right to kill other people. On the first day, there was no gun on the next day. I came to the third day, I came, asked if there were several diseased dogs, how to calculate it?
inference:
A, a false dog, the owner of the sick dog will see that other dogs don't have sick, then they know that their dogs have sick, so there will be guns in the first night. Because there is no gun, the number of dicks is greater than 1.
B, there is a doped dog, the owner of the sick dog will see there is a doped dog, because did not hear the gun on the first day, the number of sick dogs greater than 1, so the sick dog's owner will know that his dog is Daughter, there will be a gun on the next day. Since there is also a gun on the next day, the number of dick dogs is greater than 2. From this reason, there is three disease dogs if the third day is shot.
