奥数题,很有难度!There are three men A,B,C,each person may be an honest man or a liar.A. says:"B is a liarB.says:"A and B are kind person.QUESTION:who is honest man,and who is a liar?
假设A为诚实人
则B为说谎者,那么A、 C其中一人为坏人,则只能C为说谎者,成立
A好人
B说谎者
C说谎者
假设A为说谎者
那么B为诚实人,则A,C为好人,不成立

逻辑题?

不认识鸟语~~~

C honset
A、B liars

A说谎,则B说实话,则A说实话矛盾,A必说实话。
所以,B说谎。
题目应该把B说的那个B改成C。
改后,B说谎,则C必不诚实。
综上,A实,BC虚。

1,如果A不是骗子,则A说的就是真话,那么B就是骗子,
B说:A,B都是善良的人就不成立,则至少有一个是骗子,此是B是骗子为真
2如果A是骗子,则B说的就是真话,B说:A,B都是善良的人就成立,矛盾
所以
A诚实,B是骗子
