Study the following information carefully and answer the questions given below:

Ten persons P to Y live in 10 storey building but not necessarily in the same order. The bottommost floor is numbered as 1 and so on till the topmost floor is numbered as 10.

V lives on prime numbered floor but below 4th floor. S lives below V but not on the ground floor. There are as many persons live above S as below P. More than three persons live between P and Y who lives above X. One person lives between T and Y. W lives just below R. U does not live below Q.

Four of the following five are alike in a certain way and hence form a group. Which of the following does not belong to that group?

To find the person who does not belong to the group, let us first determine the floor arrangement of all ten persons (P to Y) on the 10-storey building from Floor 1 (bottommost) to Floor 10 (topmost).

Step 1: Position of V and S
V lives on a prime numbered floor below the 4th floor. The prime numbers below 4 are 2 and 3.
S lives below V but not on the ground floor (Floor 1).
If V lived on Floor 2, S would have to live on Floor 1, which violates the condition that S cannot live on the ground floor. Therefore, V must live on Floor 3, and S must live on Floor 2.

Step 2: Position of P
There are as many persons living above S as below P.
Since S lives on Floor 2, there are 10 - 2 = 8 floors above S.
Therefore, there must be 8 floors below P, which means P lives on Floor 9.

Step 3: Position of Y and X
More than three persons live between P and Y, and Y lives above X.
Since P is on Floor 9, Y must be on Floor 4 or lower to have more than 3 floors between them (at least 4 floors: Floors 8, 7, 6, and 5).
- If Y were on Floor 3, it would conflict with V.
- If Y were on Floor 2, it would conflict with S.
- If Y were on Floor 1, there would be no floor below Y for X to live on.
Thus, Y must live on Floor 4, and since Y lives above X, X must live on Floor 1.

Step 4: Position of T
One person lives between T and Y. Since Y lives on Floor 4, T can live on either Floor 6 or Floor 2. Since Floor 2 is already occupied by S, T must live on Floor 6.

Step 5: Position of R and W
W lives just below R. This requires two adjacent vacant floors.
Currently, the status of the floors is:
Floor 10: Vacant
Floor 9: P
Floor 8: Vacant
Floor 7: Vacant
Floor 6: T
Floor 5: Vacant
Floor 4: Y
Floor 3: V
Floor 2: S
Floor 1: X
The only adjacent vacant floors are Floor 8 and Floor 7. Therefore, R lives on Floor 8 and W lives on Floor 7.

Step 6: Position of U and Q
The remaining vacant floors are Floor 10 and Floor 5. Since U does not live below Q (meaning U lives above Q), U must live on Floor 10 and Q must live on Floor 5.

Summary of Floor Positions:
Floor 10: U
Floor 9: P
Floor 8: R
Floor 7: W (Prime floor)
Floor 6: T (Composite floor)
Floor 5: Q (Prime floor)
Floor 4: Y
Floor 3: V (Prime floor)
Floor 2: S (Prime floor)
Floor 1: X

Finding the odd one out:
Let us check the floors on which the given options live:
- V lives on Floor 3 (Prime number floor)
- T lives on Floor 6 (Composite/Even number floor)
- S lives on Floor 2 (Prime number floor)
- W lives on Floor 7 (Prime number floor)
- Q lives on Floor 5 (Prime number floor)
All the given persons except T live on prime-numbered floors. Therefore, T does not belong to the group.
