Correct Answer - Option 4 : S
Six persons: P, Q, R, S, T and U
Floors: 1, 2, and 3
Flat: X and Y
(1) P lives on an odd numbered floor in flat X. Therefore, we get two the following two cases here.

Case (I)
|
Case (II)
|
Floor
|
Flat - X

Flat - Y

(2) The one who is from Kolkata lives immediately above C.
(3) S lives to the west of U.
(4) P and the one who is from Kolkata do not live on the same floor.

(5) T does not live in flat Y.
(6) There is one floor between Q and the one who is from Delhi who lives above Q. Since, only flat Y of floor 3 is left for Q in case (I), case (I) eliminates here.
|
Case (II)
|

Flat - X

(7) Neither S nor Q is from Bangalore.
(8) U is either from Pune or from Agra (implies, P is from Bangalore).
(9) The one who is from Mumbai lives on the same floor on which the one who is from Agra lives (implies, S is from Mumbai and U is from Agra). Thus, the final arrangement is as follows:
|
Case (II)
|
Floor
|
Flat - X
|
Flat - Y
|

|
T (Delhi)
|
R (Kolkata)
|
2
|
S (Mumbai)
|
U (Agra)
|
1
|
P (Bangalore)
|
Q (Pune)
|
We can see that, all T, R, P, and Q live in odd numbered floor and thus forms a group.
Hence, S does not belong to that group.
