P, Q, R, S, T and U are six friends. They are sitting in a row facing south. P is sitting to the immediate left of R and second to the right of S. T is sitting to the immediate right of R. U is sitting second to the left of R. Q is sitting to the immediate left of S. Who is sitting at the extreme right end of the row?

Solving Seating Arrangement Puzzle Facing South
This problem involves arranging six friends (P, Q, R, S, T, and U) in a straight row based on given clues. They are all facing South. We need to use the given clues to determine their exact order.
Understanding Relative Positioning (Facing South)
When individuals are seated in a row facing South:
- "To the immediate left" means the person is situated immediately to your West.
- "To the immediate right" means the person is situated immediately to your East.
- "Second to the left" means two positions to your West.
- "Second to the right" means two positions to your East.
For the "extreme ends" of the row, it is common in diagrams to consider the "extreme left end" as the leftmost position (most West) and the "extreme right end" as the rightmost position (most East) in the linear arrangement diagram.
Constructing the Seating Arrangement
Let's build the arrangement step-by-step based on the clues:
- Clue 1: P is sitting to the immediate left of R. Since they face South, P is immediately West of R. Arrangement so far: P R
- Clue 2: P is sitting second to the right of S. Since they face South, P is two positions East of S. This places S two positions West of P. Arrangement: S _ P. Combining with Clue 1: S _ P R
- Clue 3: T is sitting to the immediate right of R. Since they face South, T is immediately East of R. Arrangement: P R T. Combining with previous: S _ P R T
- Clue 4: U is sitting second to the left of R. Since they face South, U is two positions West of R. Given P is immediate West of R, U must be immediate West of P. Arrangement: U P R. Combining with previous: S U P R T
- Clue 5: Q is sitting to the immediate left of S. Since they face South, Q is immediately West of S. Arrangement: Q S. Combining: Q S U P R T
Final Arrangement from West to East
The complete arrangement of the friends from West to East is:
| Position (West to East) | Friend |
|---|---|
| 1st (Most West) | Q |
| 2nd | S |
| 3rd | U |
| 4th | P |
| 5th | R |
| 6th (Most East) | T |
Identifying the Friend at the Extreme Right End
Assuming "extreme right end" refers to the person at the rightmost position in the linear arrangement diagram (most East position), based on our final arrangement Q S U P R T (from West to East):
The person at the extreme right end is T.
This is the position furthest to the East in the row.
Step-by-Step Solution Summary
1. Interpret each seating clue considering the friends are facing South.
2. Use the clues to progressively build the linear arrangement of the six friends.
3. The final arrangement determined from West to East is Q, S, U, P, R, T.
4. Identify the friend positioned at the extreme rightmost point of this linear arrangement.
5. This position is occupied by T.
Revision Table: Seating Arrangement Clues Analysis
| Clue | Interpretation (Facing South) | Implied Position Relative to Others |
|---|---|---|
| P immediate left of R | P is West of R | ...P R... |
| P second right of S | P is East of S | S _ P... |
| T immediate right of R | T is East of R | ...R T... |
| U second left of R | U is West of R | U _ R... (leading to U P R) |
| Q immediate left of S | Q is West of S | Q S... |
Additional Information: Linear Seating Arrangements Facing South
Solving linear seating arrangements, especially those facing South, requires careful distinction between your own left/right and the seated individuals' left/right. When facing South, the direction of 'left' is towards the West, and 'right' is towards the East.
Common terms used in such puzzles:
- Immediate Left/Right: Adjacent positions.
- Second/Third Left/Right: Positions separated by one/two individuals.
- Extreme Ends: The persons at the very beginning and end of the row. While facing direction dictates relative left/right *within* the row, the "extreme ends" in diagrams usually refer to the physically leftmost (West) and rightmost (East) positions.
Practicing various arrangements helps in quickly interpreting clues and building the sequence accurately.
Important Questions from Linear Arrangement
Eight friends, A, B, C, D, E, F, G and H, are sitting in two lines of four persons each. Both the lines are facing each other. A is facing D. E is to the immediate left of G. H is to the immediate right of B. C is facing G. F is facing H. B is to the immediate right of the person who is facing G. D is to the immediate left of F. Which four persons are sitting in the same line?
Nine employees, K, L, M, N, O, P, Q, R and S, are sitting in the office in a straight line, all facing the east. O is third to the right of M. K is third to the left of P. Q is between P and S. N is fourth to the right of M. P is to the immediate right of N. R is fourth to the left of O. Which of the following statements is NOT correct?
Eight north-facing restaurants named P, Q, R, S, T, U, V and W are located in a straight line. S is second to the left of T. W is third to the left of P. T is between P and V. S is third to the left of V. W is to the immediate right of U. R is third to the right of P. Who is sitting fourth to the right of S?
Anamika, Gopal, Nischal, Vanmayi, Shresta and Sripad are sitting in a straight line facing the north. Nischal is to the immediate left of Gopal. Shresta is between Anamika and Sripad. Sripad is at the second place from the right end. Four persons are sitting between Nischal and Vanmayi. If Gopal and Sripad interchange their positions, then who will be sitting between Vanmayi and Shresta?
A question is given, followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements is sufficient to answer the question. Read both the statements and select the appropriate answer.
Question: How many people are standing in the row where all people are facing north?
Statements:
(I) A is fourth from the left end; M is second to the right of A; and R is second from the left end.
(II) M is fourth from the right end; only two people Stand between M and B.
