Zorluk: OrtaSeating Arrangement

Five colleagues—K, L, M, N, and O—are seated in a single straight row, with some facing North and others facing South. The following conditions apply to their seating arrangement:

- M sits at the exact center of the row and faces North.
- L sits second to the right of M.
- K sits to the immediate left of L.
- N and O are immediate neighbors, and O does not sit at an extreme end of the row.
- K and N face the same direction, which is opposite to the direction L faces.
- The persons sitting at the extreme ends of the row face opposite directions.
- O faces South.

Based on this arrangement, what is the position of N with respect to K?

  1. A
    Third to the left
  2. B
    Second to the right
  3. Third to the rightCevap
  4. D
    Second to the left

Cevap

N sits third to the right of K.
The correct answer accurately places K at position 4 facing South and N at position 1. Because K faces South, the seats to K's right are positions 3, 2, and 1. Being three seats away, N is third to the right of K.

Adım Adım Çözüm

1
Determine the exact positions of M, L, and K.
Assume positions are numbered 1 to 5 from left to right. M is at position 3 facing North. L is at position 5 (second to the right of M). Because K is to the immediate left of L, L must face North (if L faced South, L's left would be outside the row). Thus, K is placed at position 4.
Establishing the anchor points using explicit positioning rules and boundary logic.
2
Place N and O in the remaining seats.
Positions 1 and 2 are empty. Since N and O are neighbors and O cannot be at the extreme end (position 1), O must be placed at position 2 and N at position 1.
Using negative constraints to lock down the remaining positions.
3
Determine the facing directions of K, N, and O.
L faces North. K and N face opposite to L, so both face South. O faces South (given). The ends are N (facing South) and L (facing North), which satisfies the rule that extreme ends face opposite directions.
Applying the relative facing direction conditions to complete the setup.
4
Calculate N's position with respect to K.
K is at position 4 and faces South. N is at position 1. From K's perspective (facing South), positions 3, 2, and 1 are towards the right. Since N is three seats away, N is third to the right.
Resolving the final question by orienting left/right correctly based on K's facing direction.
