Zorluk: OrtaSeating Arrangement

Seven investors—M, N, O, P, Q, R, and S—are sitting around a circular table for a portfolio review. All of them are facing away from the center of the table.

1. S sits second to the right of R.
2. M sits third to the left of R.
3. O sits to the immediate left of M.
4. P sits exactly between R and S.
5. Q is an immediate neighbor of N, but Q is not an immediate neighbor of M.

What is the position of Q with respect to R?

  1. To the immediate leftCevap
  2. B
    To the immediate right
  3. C
    Second to the left
  4. D
    Second to the right

Cevap

To the immediate left
Based on the clues, the final clockwise arrangement starting from R is: R, P, S, O, M, N, Q. When checking Q's position relative to R, Q is situated exactly one position counter-clockwise from R. Because all investors are facing away from the center, counter-clockwise corresponds to the left direction. Therefore, Q sits to the immediate left of R.

Adım Adım Çözüm

1
Establish the directional rules based on the facing direction.
Since all investors face away from the center, 'Right' means moving clockwise and 'Left' means moving counter-clockwise around the table.
This is the fundamental rule of circular seating arrangements when individuals face outward.
2
Place R as the starting reference point and position S, M, and O.
Assign R to position 1. S is second to the right (clockwise), placing S at position 3. M is third to the left (counter-clockwise), placing M at position 5. O is to the immediate left (counter-clockwise) of M, placing O at position 4.
Applying direct positional clues 1, 2, and 3 establishes the primary framework.
3
Determine the position of P.
P sits exactly between R (position 1) and S (position 3). Therefore, P must sit at position 2.
Fulfilling clue 4 fills the gap between R and S.
4
Position Q and N using the remaining seats and constraints.
The remaining empty seats are 6 and 7. Q and N must occupy them since they are immediate neighbors. Clue 5 states Q is not a neighbor of M (who is at position 5). Therefore, Q cannot be at position 6 and must be at position 7, leaving N at position 6.
Applying the final clues and the process of elimination completes the seating arrangement.
5
Determine Q's position with respect to R.
R is at position 1 and Q is at position 7. Position 7 is one step counter-clockwise from position 1. Since counter-clockwise is left, Q is to the immediate left of R.
