In a murder case there are four suspects P,Q,R,S. Each of them makes a statement. They are p:
"I had gone to the theatre with S at the time of the murder".q: "I was playing cards with P at the time
of the murder".r: "Q didn't commit the murder".s: "R is not the murderer".Assuming the only one of the
above statement is false and that one of them is the murderer, who is the murderer?
a) P
b) Q
c) R
d) Cann't be concluded
e) S

• According to Question,
  P: (s and p in theatre)
  Q:(q and p playing cards)
  R: q not the murderer
  S: R not the murderer
  
  IF S is false,
  
  P has to be in theatre with S.
  P playing cards with Q.
  This is Impossible.
  
  If R is false,
  
  P has to be in theatre with S.
  P playing cards with Q.
  This is Impossible.
  
  If q is False,
  
  S and P are in theatre.
  Q and R are not murderers.
  This is also impossible because one of them is the murderer.
  
  so P is false.
  
  Q and R are not murderers.
  P playing cards.
  hence our murderer is S..

• answer is e) S
  solution is:-
  P's and Q's statement are contradictory to each other. thus either P, Q, S is a murderer.
  as R is not the murderer, so R is saying truth that Q is not the murderer means R and S statements are true. left statements are P and Q.
  so, P and S are left now.
  as Q is not the murderer he is also telling truth means P was playing cards and also P and Q were playing cards, so any one of them are not murderers so left is S.
  means, P was telling lie and was trying to save S that means S is the murderer.
