Study the following information and select guilty person. Ram was visiting a place where inhabitants always answer any question with two sentences. One of these is always true while other is always false. While on the visit he found that his bag has been stolen and he suspected three persons those visited his guest room. He was sure that only one person is guilty. When he questioned them they replied as follows. R ∶ S did not do it. I did not do it. S ∶ I did not do it. P did not do it. T ∶ I did not do it. I did not know who did it. Correct Answer S

On analysing the statements: (One is correct and other is wrong.)

R ∶ S did not do it. I did not do it.

S ∶ I did not do it. P did not do it.

If 'S did not do it' is correct then statement of S 'I did not do it' is also correct. This implies that statement of R 'I did not do it' is false and statement 'P did not do it.' is false. This further implies that P and R did it which is not possible. Thus, S is guilty and both the first statements of R and S are false. 

T ∶ I did not do it. I did not know who did it.

Here, first statement is true and second is false.

Hence, S is guilty.
