There are two apartments in a village in which the people from one apartment(Say Aprmnt 1) speak only truth where as the people from second apartment speak only lies(Say Aprtmnt 2) Now the question is you want to go to the apartment in which people speak only truth. You have a chance to ask only one question to any person in apartment and decide which is the correct apartment. What is the question you are going to ask to know which is the correct apartment.? (Condition: Only One Question Is To Be Asked)

• Which is your apartment?
  
  Person who lives in apartment 1 will show you apartment 1 as they always speaks the truth.
  Person who lives in apartment 2 will show you apartment 1 as the always speaks lies.
  So all of them will always show you the apartment in which people speak only truth.
