Directions (84-87) : Study the following information carefully and answer the questions given below:
A certain number of persons sit in a row facing north direction. Two persons sit between N and Q who is the only neighbour of B. W sits 5th to the left of L who sits immediately right of N. W sits exactly middle of the row. The number of persons sit between W and N is the same as the number of persons sit between W and T . Z sits 2nd to the right of H. Three person sits between T and H. O sits just left of A and just right of E who doesn’t sit adjacent to W.

Which of the following pair of persons are adjacent to each other?

Correct Option: T , E

Let us analyze the given information step-by-step to determine the seating arrangement of persons in a row facing North:

Step 1: Determine the positions of L, N, W, Q, and B

1. W sits 5th to the left of L who sits immediately right of N.
So, the arrangement of these positions relative to each other is:
W _ _ _ _ N L

2. "Two persons sit between N and Q who is the only neighbour of B."
Since Q is the only neighbor of B, B must be at one of the extreme ends of the row, and Q sits adjacent to B (specifically to the right of N or left of N).
If Q were to the left of N (between W and N):
W _ Q _ _ N L
Here, Q has two neighbors, which contradicts "Q is the only neighbour of B".
Thus, Q must be to the right of N (specifically to the right of L):
N L _ Q B
Here, B is at the extreme right end, so Q has only one neighbor (B).

Combining these positions, the right section of the row is:
W _ _ _ _ N L _ Q B

Step 2: Determine the total number of persons and row length

1. From W to B, let us count the positions:
Position 1: W
Position 2: _
Position 3: _
Position 4: _
Position 5: _
Position 6: N
Position 7: L
Position 8: _
Position 9: Q
Position 10: B (Extreme Right End)

2. "W sits exactly middle of the row."
Since B is at Position 10 (which is 9 positions to the right of W), there must be 9 positions to the left of W as well.
Therefore, W is at Position 10 from the left end, making the total number of persons in the row equal to:
$9+1+9=19$

Let us number the 19 positions from left to right (1 to 19):
- Position 10: W
- Position 15: N
- Position 16: L
- Position 18: Q
- Position 19: B

Step 3: Place T, H, Z, E, O, and A

1. "The number of persons sit between W and N is the same as the number of persons sit between W and T."
Number of persons between W (Pos 10) and N (Pos 15) is 4.
So, there are 4 persons between W (Pos 10) and T.
Since N is to the right of W, T must be to the left of W.
Position of T = $10-5=5$

2. "Three persons sit between T and H."
Position of T is 5.
If H were to the right of T: Position of H = $5+4=9$
If H were to the left of T: Position of H = $5-4=1$

3. "Z sits 2nd to the right of H."
If H = 9, then Z = 11 (just to the right of W at 10).
If H = 1, then Z = 3.

4. "O sits just left of A and just right of E who doesn’t sit adjacent to W."
This means E, O, A sit together in consecutive positions: E O A.
Since E cannot sit adjacent to W (Positions 9 and 11 are adjacent to W):
- If H = 9, Z = 11, then positions available to the left of W (Pos 10) are restricted.
- If H = 1, Z = 3:
Positions 1 to 5: H _ Z _ T
This leaves positions 6, 7, 8 vacant.
Placing E, O, A in positions 6, 7, 8 perfectly fits:
- Position 4: E (not adjacent to W at 10, sits adjacent to T at 5)
- Wait, let's list the positions: 1: H, 2: _, 3: Z, 4: E, 5: T -- wait!
Let's check positions 4, 6, 7, 8:
If E = 4, O = 5 (conflict with T at 5).
If E = 6, O = 7, A = 8:
Position 6 is not adjacent to W (Pos 10). This gives a consecutive block E (6), O (7), A (8).

Let's re-verify the block E, O, A with T = 5:
- Position 5: T
- Position 6: E
- Position 7: O
- Position 8: A
Thus, T and E are immediately adjacent to each other at positions 5 and 6 respectively.

Conclusion:

T sits at position 5 and E sits at position 6. Therefore, T , E form a pair of persons who are adjacent to each other.
