Understanding the Clues
We need to arrange six people (P, Q, R, S, T, U) in a row facing north based on the given conditions.
- Clue 1: P is second to the left of S. (Relative order: P _ S)
- Clue 2: P is third to the right of U. (Relative order: U _ _ P)
- Clue 3: Two people sit between R and Q. (This implies a gap of 3 positions between R and Q)
- Clue 4: Q is not a neighbour of S.
Deducing Fixed Positions
Combining Clue 1 and Clue 2 establishes a relative sequence. If P is third to the right of U, and P is second to the left of S, the order must be U _ _ P _ S.
Considering 6 positions in the row (1 to 6, left to right):
- The sequence U _ _ P _ S requires 6 slots.
- This means U is at position 1, P is at position 4 (1+3), and S is at position 6 (4+2).
- So, the arrangement is: $U _ _ P _ S$
Placing Q, R, and T
The people left to be placed are Q, R, and T. The available positions are 2, 3, and 5.
- From Clue 3, there are two people between R and Q. This means their positions must differ by 3. The only pair of available positions {2, 3, 5} that differs by 3 is (2, 5).
- Therefore, Q and R must be in positions 2 and 5.
- From Clue 4, Q cannot be next to S. Since S is at position 6, Q cannot be at position 5.
- This means Q must be at position 2, and R must be at position 5.
- The remaining person, T, must be in the only remaining position, which is 3.
Final Arrangement and Answer
The complete arrangement from left to right is: U Q T P R S
- Position 1: U
- Position 2: Q
- Position 3: T
- Position 4: P
- Position 5: R
- Position 6: S
The question asks who sits to the immediate left of P. P is at position 4. The position immediately to the left is position 3.
The person sitting at position 3 is T.
