The reporter visited a company. There are two types of people in this company: honest people who only tell the truth, and scammers who only say lies. At lunch, all the people in the company sat around the dining table. The reporter asked everyone in the company the same question: "Is the person on your left honest ?" Everyone replied, "No ". Then, the reporter asked the company's boss how many people there were, and the boss said there were 25 people. After returning home, the reporter remembered that he had forgotten to ask the boss whether he was a real man or a liar and hurriedly called. When the boss was absent, the secretary answered the question. She replied, "there are 36 people in the company. Our boss is a liar ." Based on the above situation, please help the reporter determine whether the boss is a liar? How many people are there in the company?

Analysis: to deal with logic problems, first carefully analyze each condition and find the starting point, that is, find a breakthrough. This logic question can basically get some information from every condition immediately. There is no so-called starting point, or it is a starting point everywhere. Condition 1: Everyone says that the person on the left is not an honest person. It is inferred from this that if two adjacent people are honest people, then the people on the right are not honest people (fake words). There is a conflict. It is impossible for the two adjacent persons to be honest people; if the two adjacent persons are the same swindlers, the two on the right side are not honest people (truth). They are in conflict. It is impossible for the two adjacent persons to be the same. Therefore, the two adjacent persons must be an honest person sitting next to a liar. In this way, they will be surrounded by an even number of people. Condition 2: The boss says there are 25 people in the company. "There are 25 people in the company", in conflict with condition 1's conclusion that "the number of people in the company is an odd number", and the boss is a liar. Condition 3: There are two types of people in the company: honest people who only tell the truth, and scammers who only say false things. Note: Condition 4: The Secretary said: there are 36 people in the company, and our boss is a liar. According to the inference of condition 2, The Secretary said that "our boss is a liar" is the truth, and Condition 3 knows that she is an honest man. Therefore, the secretary said that "36 people in the company" is also the truth. The first Chinese Culture network: http://www.hywh.net/
