Logical puzzle. 3 Persons, each 2 statements, 1 lie, 1 true I got a question at university which I cannot solve. We are currently working on RSA encryption and I'm not sure what that has to do with the question.
Maybe I miss something. Anyway, here is the question:
Inspector D interviews 3 people, A, B and C. All of them give 2 statements, where 1 statement they say is true and 1 is wrong. The inspector knows that and he also knows that exactly one is guilty. 
Here are the statements:
c did it, but b doesn't know it, just a lucky guess..
Relation to RSA would be that you have one secret and one public verifiable statement. But it is somewhat abstract.
