- A, who is from Lajpat Nagar, is sitting exactly between X and Z.
- The person from Saket is sitting second to the right of the person from Lajpat Nagar.
- C is sitting third to the left of X.

Four of the following five pairs are alike in a certain way based on their positions in the above arrangement and so form a group. Which of the following does NOT belong to the group?

(b) Z - Mehrauli

(c) D - Okhla

Accepted Answer

**Solution:**

1. First, arrange the eight people in a circle facing the center based on the clues.

2. From the clue, W is third to the left of Y. Since they face the center, left means counterclockwise.

3. The person from Dwarka is immediately to the right (clockwise) of W, and W is not from Okhla.

4. B is fourth to the right of Z.

5. Z is not a neighbor of Y, and neither B nor Z is an immediate neighbor of W.

6. X is from Chanakyapuri and is third to the right of the person from Dwarka.

7. The person from Mehrauli is second to the left of the person from Chanakyapuri.

8. The person from Rohini is second to the left of W.

9. A is from Lajpat Nagar and sits exactly between X and Z.

10. The person from Saket is second to the right of the person from Lajpat Nagar.

11. C is third to the left of X.

**After placing all individuals and their respective places, the pairs are:**

- B is from Rohini
- Z is from Karol Bagh (not Mehrauli)
- D is from Okhla
- Y is from Saket
- X is from Chanakyapuri (not Dwarka)

**Analysis:**

- Except for Z - Mehrauli and X - Dwarka, all other pairs correctly match the person with their place.

- Since X is from Chanakyapuri, not Dwarka, and Z is not from Mehrauli, these two pairs do not fit the pattern.

- Among the options, only (b) Z - Mehrauli does not belong to the group formed by the other pairs.

**Answer:** (b) Z - Mehrauli
