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:
A's statement is either (t,f) or (f,t). if it is (f,t) it means both him and B are guilty. Assuming there is a solution to this puzzle A is (t,f) and so C is guilty.
Further B is not guilty so his second statement is false. This does not mean C is not guilty, its just that B does not know. Note also C is (f,t) so B does not know who did it anyway.
t=true
f=false
