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.

How many persons sit between E and W?

The correct option is Two.

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

1. W sits exactly in the middle of the row.

2. W sits 5th to the left of L. This means there are 4 persons between W and L:
W _ _ _ _ L

3. L sits immediately to the right of N. So N is positioned just to the left of L:
W _ _ _ N L

4. The number of persons sitting between W and N is 3 (since W _ _ _ N L).
Since the number of persons between W and N is the same as between W and T, there must also be 3 persons between W and T. Since N is to the right of W, T must be to the left of W:
T _ _ _ W _ _ _ N L

5. Two persons sit between N and Q, and Q is the only neighbour of B. Since Q is the only neighbour of B, B must be sitting at an extreme end, and Q is adjacent only to B. If Q were to the left of N, it would conflict with W's position. Thus, Q sits 2 places to the right of N:
T _ _ _ W _ _ _ N L _ Q B

6. Three persons sit between T and H. Since H cannot go right towards W without conflicting, H sits to the left of T:
H _ _ _ T _ _ _ W _ _ _ N L _ Q B

7. Z sits 2nd to the right of H:
H _ Z _ T _ _ _ W _ _ _ N L _ Q B

8. O sits just left of A and just right of E (so the block is E O A). E does not sit adjacent to W.
Looking at the empty slots, between T and W there are 3 positions: T [ _ _ _ ] W.
Placing E O A in these three positions gives:
T E O A W _ _ _ N L _ Q B
Here, E is adjacent to T, O is between E and A, and E is not adjacent to W (A is adjacent to W), which satisfies all conditions perfectly!

Now, let us trace the complete arrangement from left to right:
H _ Z _ T E O A W _ _ _ N L _ Q B

We need to find how many persons sit between E and W:
Looking at the sequence: E O A W
The persons sitting between E and W are O and A.

Therefore, exactly Two persons sit between E and W.
