Zorluk: OrtaSeating Arrangement

Six friends (P, Q, R, S, T, and U) are seated in a straight line facing North. Read the following information carefully:

1. P sits third to the left of S.
2. Neither P nor S sits at the extreme ends of the line.
3. R sits to the immediate right of S.
4. T is not an immediate neighbor of P.
5. Q sits to the left of U.

Based on the final seating arrangement, match the individuals (List I) with their correct positional descriptions (List II).

  • QSits at the extreme left end of the row
  • USits exactly between P and T
  • TSits to the immediate left of S
  • SSits second to the right of U

Cevap

The final arrangement from left to right is Q, P, U, T, S, R. Therefore, Q sits at the extreme left, U sits between P and T, T sits immediately left of S, and S sits second to the right of U.
The fully deduced seating arrangement from left to right is Q, P, U, T, S, R. Matching each person to their derived positional fact yields the correct alignment without any contradictions.

Adım Adım Çözüm

1
Determine the exact positions of P and S.
P is at position 2 and S is at position 5.
Since P is third to the left of S, the possible pairs for (P, S) are (1, 4), (2, 5), and (3, 6). However, neither P nor S can sit at the extreme ends (positions 1 and 6). Thus, the only valid placement is P at 2 and S at 5.
2
Place R in the arrangement.
R is at position 6.
The condition states R is to the immediate right of S. Since S is at position 5, R must take position 6.
3
Place T in the arrangement.
T is at position 4.
The remaining empty positions are 1, 3, and 4. T cannot be an immediate neighbor of P (who is at 2), meaning T cannot be at 1 or 3. Therefore, T must take position 4.
4
Place Q and U in the arrangement.
Q is at position 1 and U is at position 3.
The only remaining spots are 1 and 3. Since Q must sit to the left of U, Q takes position 1 and U takes position 3.
