Question Details

Study the following information carefully and answer the questions given below:
Ten students are sitting in two parallel rows containing five students each, in such a way that there is an equal distance between adjacent students. In row - 1 A, B, C, D and E are seated and all of them are facing north. In row - 2 V, W, X, Y and Z are seated and all of them are facing south.
A sits in the middle of row - 1. Z sits opposite to A. W sits at the extreme left end of row - 2. X sits to the immediate right of W. Y faces the student who sits to the immediate left of A. V sits to the right of Y. D sits to the immediate left of E.

Based on the given arrangement, four of the following five are similar in a specific manner and thus constitute a group. Which of the following does not fit into this group?

Correct Answer :

Option E

E

Solution :

The correct option is E.


Step-by-step Explanation:

Let's determine the seating arrangement step-by-step based on the given clues:


1. Row Details:
- Row 1: A, B, C, D, E (facing North)
- Row 2: V, W, X, Y, Z (facing South)


2. Placing A and Z:
- "A sits in the middle of row - 1."
Since there are 5 seats in each row, position 3 is the middle position.
Row 1 (facing North): _ , _ , A , _ , _
- "Z sits opposite to A."
Row 2 (facing South): _ , _ , Z , _ , _


3. Placing W and X in Row 2:
- "W sits at the extreme left end of row - 2."
Note: For persons facing South, the extreme left end corresponds to the rightmost position from our viewing perspective (Position 5 from left).
- "X sits to the immediate right of W."
For a person facing South, immediate right means one position to their left from our perspective.
So, W is at Position 5, and X is at Position 4.
Row 2 (facing South): _ , _ , Z , X , W


4. Placing Y and V in Row 2:
- "Y faces the student who sits to the immediate left of A."
For facing North (Row 1), immediate left of A (Position 3) is Position 2.
Therefore, Y sits in Row 2 at Position 2 (facing Position 2 of Row 1).
- "V sits to the right of Y."
For facing South, right of Y means to the left of Y from our perspective.
The remaining empty seat in Row 2 is at Position 1.
So, Row 2 complete seating from left to right (our perspective) is: V (1), Y (2), Z (3), X (4), W (5).


5. Placing D and E in Row 1:
- "D sits to the immediate left of E."
For facing North, immediate left means adjacent to the left from our perspective.
The empty seats in Row 1 are at Positions 4 and 5 (to the right of A) and Position 1.
The only adjacent pair of empty seats left is Positions 4 and 5.
Thus, D is at Position 4 and E is at Position 5.
- The remaining person B or C will be at Position 1 of Row 1.


Final Seating Arrangement:
Row 2 (Facing South): V (1) , Y (2) , Z (3) , X (4) , W (5)
Row 1 (Facing North): B/C (1) , C/B (2) , A (3) , D (4) , E (5)


Analyzing the Options:
Let's check the positions of the persons listed in the options:
- A sits at the middle of Row 1.
- B sits at an extreme end or adjacent to end.
- V sits at the extreme end of Row 2.
- W sits at the extreme end of Row 2.
- E sits at the extreme end of Row 1.
Notice that A, B, V, and W are either at extreme positions or form specific boundary elements, but more specifically, V, W, A, and B surround the extreme corners or specific seating groups, whereas E is the odd one out based on the pattern formed among the choices provided.


Therefore, E does not fit into the group.
