GIVEN:
Ø A 7 – storey building, where the Ground Floor = 1st Floor
Ø 7Persons – P, Q, R, S, T, U and V
Ø 7 Cities– Delhi, Mumbai, Patna, Chennai, Bangalore, Lucknow and Kolkata

SOLUTION:
These types of questions can be best solved by the tabulation method
Ø If persons / days are mentioned in the question then the first column of the table will always be persons/days
Ø Here there are 7 persons, then the1stcolumn will be persons
Ø Always start filling the Table from thebottomif there are more than one possibilities

CLUE 1: Only three people live above the floor on which P lives

Ø ThereforeP lives on the4th floor (7 – 3 = 4)

CLUE 2: Only one person lives between P and the one travelling to Bangalore
Ø Going by the clue, the person travelling to Bangalore is onalternate floor from P. The person can be in the floor either above or below P
Ø That gives us 2 options
·        Above P – 6th Floor
             OR
·        Below P – 2nd Floor

CLUE 4: U lives immediately below the one travelling to Mumbai

CLUE 5: Only three people live between the ones travelling to Bangalore and Patna

Ø From theclue 2, it is clear that the person travelling to Bangalore is either in floor2 or6
Ø So if person travelling to Bangalore is in floor 2 then the person travelling to Patna will be in floor 6 and vice versa (because only three people live between the ones travelling to Bangalore and Patna)
Ø Therefore, the person travelling to Mumbai cannot be in floor 2 or 6
Ø ByClue 4, U will be in floor 3
Ø Hence,4th floor = P = Mumbai

·        Floors 1& 2Ø Here the tentative floors where T and R can be are as follows
·        Floors 5& 6
·        Floors 6& 7

CLUE 7: Only two people live between Q and the one travelling to Kolkata. The one travelling to Kolkata lives below the floor on which Q lives
Ø This shows that the person travelling to Kolkata and Q are2 floors apart, with the person travelling to Kolkata below Q
Ø Now the person travelling to Kolkata cannot be in floor 1, because then Q would be in floor 4 which is not possible as4thfloor = P
Ø If the person travelling to Kolkata is in floor 3, then Q will be in floor 6
Ø The Kolkata person cannot be in floors 5 or 7 as there will be no floor for Q above them
Ø Since Q is confirmed to be in floor 6, T and R combination cannot be available in the floors 5, 6 and 7
Ø Therefore,3rd Floor = U = Kolkata
                  6th Floor = Q = Bangalore or Patna
                  1st Floor = R
                   2nd Floor = T = Bangalore or Patna
