Question

Difficulty: MediumSeating Arrangement

Six colleagues—P, Q, R, X, Y, and Z—are seated in two parallel rows containing three people each, such that there is an equal distance between adjacent persons. In Row 1, P, Q, and R are seated and all of them are facing North. In Row 2, X, Y, and Z are seated and all of them are facing South. In this seating arrangement, each member seated in a row faces exactly one member of the other row.

The following information is given:
1. X is not sitting at any extreme end of the row.
2. R sits to the immediate right of the person who faces X.
3. Z faces the person who sits to the immediate left of P.

Based on the above arrangement, who sits to the immediate right of X?

  1. ZAnswer
  2. B
    Y
  3. C
    P
  4. D
    R

Answer

Z
Based on the conditions, X is in the middle of Row 2 facing South. P must be in the middle of Row 1 facing X, so that R can sit on P's immediate right (North-facing right). Q is on the immediate left of P, and Z faces Q. Thus, from the viewer's perspective, Row 2 is ordered Z, X, Y (left to right). Since Row 2 faces South, X's immediate right is to the viewer's left, which is occupied by Z.

Step-by-Step Solution

1
Determine X's position in Row 2.
X is seated exactly in the middle of Row 2.
The first condition states that X is not at any extreme end. Since there are only 3 seats, X must be in the center.
2
Determine the positions of P and R in Row 1.
P is in the middle of Row 1 (facing X) and R is at the extreme right end of Row 1.
Since X is in the middle, the person facing X must be in the middle of Row 1. R sits to the immediate right of this person. In a North-facing row, 'immediate right' is to the viewer's right. Thus, P is the person facing X, and R occupies the rightmost seat.
3
Determine the position of Z in Row 2.
Z is at the left end of Row 2 from the viewer's perspective.
Z faces the person sitting to the immediate left of P. The immediate left of P (middle) is the leftmost seat of Row 1, occupied by Q. Therefore, Z faces Q, placing Z on the left end of Row 2.
4
Find the person sitting to the immediate right of X.
Z sits to the immediate right of X.
X is in Row 2 and facing South. For South-facing individuals, their 'right' is to the viewer's left. Since Z is seated to the viewer's left of X, Z is on X's immediate right.
