Answer
Fifth
Why?
Start with those statements that give us fixed positions of certain variables. 1) G lives on even numbered floor. 2) G is from Tamil Nadu. 3) Three persons live between L and G. 4) The person from Assam lives immediately below G’s floor. 5) The person from West Bengal lives on the floor immediately below the floor on which the person from Assam lives. 6) N lives immediately above G’s floor and immediately below K’s floor. From all this information we get two possibilities, Case I Floors States Persons 8 L 7 6 K 5 N 4 Tamil Nadu G 3 Assam 2 West Bengal 1 Case II Floors States Persons 8 K 7 N 6 Tamil Nadu G 5 Assam 4 West Bengal 3 2 L 1 7) Three people live between J and the person from Assam. Case I Floors States Persons 8 L 7 J 6 K 5 N 4 Tamil Nadu G 3 Assam 2 West Bengal 1 Case II Floors States Persons 8 K 7 N 6 Tamil Nadu G 5 Assam 4 West Bengal 3 2 L 1 J 8) Three persons live between the persons from Bihar and West Bengal. 9) Four persons live between the persons from Bihar and Maharashtra. Case I Floors States Persons 8 L 7 J 6 Bihar K 5 N 4 Tamil Nadu G 3 Assam 2 West Bengal 1 Maharashtra Case II Floors States Persons 8 Bihar K 7 N 6 Tamil Nadu G 5 Assam 4 West Bengal 3 Maharashtra 2 L 1 J 10) There are five floors between the floors on which J and the person from Karnataka live. So case I get discarded. Case II Floors States Persons 8 Bihar K 7 Karnataka N 6 Tamil Nadu G 5 Assam 4 West Bengal 3 Maharashtra 2 L 1 J 11) H lives on the even numbered floor. 12) I does not belong to Assam. 13) L does not belong to Rajasthan. Case II Floors States Persons 8 Bihar K 7 Karnataka N 6 Tamil Nadu G 5 Assam M 4 West Bengal H 3 Maharashtra I 2 Punjab L 1 Rajasthan J We see that ‘M’ is the person from Assam and he lives on the 5 th floor.
