**Question:** Who is standing behind O in the queue?

Accepted Answer

**Solution:**

1. Counters are aligned west to east as D, C, B, A (D is westernmost, A easternmost).

2. Number of persons at counters D and A are equal, and both have the first person as female.

3. Counter B has fewer persons than C, and both have fewer persons than A.

4. The first person at counter B is a male and unmarried.

5. R is married to Q (female), and only one person stands to the east of R.

6. N (female) is married to K, and N does not stand in the same queue as O (male).

7. P (male) stands immediately ahead of M, who is married to J.

8. More than one person stands to the west of P.

9. Q stands immediately ahead of S, who stands to the west of O.

10. L is married to U (female), and L stands to the west of T (male).

11. The last person at counter A is female and not married to K.

12. The wife of L does not stand first in her queue.

From the above, O is male and stands east of S and west of Q. Since P stands immediately ahead of M, and more than one person is west of P, P must be behind O in the queue.

Therefore, the person standing behind O is **P**.
