Twelve persons sit in two parallel rows such that six persons sit in each row. In row 1 - O, K, L, M, N and Q sit and face the south direction while in row 2 - A, B, C, D, E and F sit and face the north direction but not necessarily in the same order. The persons sit in row 1 face the persons sit in row 2 and vice versa. Which person faces Q?

Statements:

I. One person sits between D and the person who faces K. Two persons sit between N and L. One person sits between B and A. F sits to the left of E. M neither faces E nor sits to the left of O.

II. N neither faces D nor sits adjacent to the person who faces D. More than two persons sit to the right of F. K and B don’t sit at the end. O doesn’t sit adjacent to N and L.

III. L and K do not sit adjacent to each other. B neither faces N nor sits adjacent to the person who faces N. More than one person sits to the right of D who does not sit adjacent to E. E and F don’t sit at the end.

Question

Twelve persons sit in two parallel rows such that six persons sit in each row. In row 1 - O, K, L, M, N and Q sit and face the south direction while in row 2 - A, B, C, D, E and F sit and face the north direction but not necessarily in the same order. The persons sit in row 1 face the persons sit in row 2 and vice versa. Which person faces Q?

Statements:

I. One person sits between D and the person who faces K. Two persons sit between N and L. One person sits between B and A. F sits to the left of E. M neither faces E nor sits to the left of O.

II. N neither faces D nor sits adjacent to the person who faces D. More than two persons sit to the right of F. K and B don’t sit at the end. O doesn’t sit adjacent to N and L.

III. L and K do not sit adjacent to each other. B neither faces N nor sits adjacent to the person who faces N. More than one person sits to the right of D who does not sit adjacent to E. E and F don’t sit at the end.

Accepted Answer

**Solution:**

1. We have two rows of 6 persons each:
   - Row 1 (faces south): O, K, L, M, N, Q
   - Row 2 (faces north): A, B, C, D, E, F

2. Persons in row 1 face persons in row 2 directly opposite them.

3. Using all statements I, II, and III together, we deduce the seating arrangement:

- From statement I:
     - One person sits between D and the person who faces K.
     - Two persons sit between N and L.
     - One person sits between B and A.
     - F sits to the left of E.
     - M neither faces E nor sits to the left of O.

- From statement II:
     - N neither faces D nor sits adjacent to the person who faces D.
     - More than two persons sit to the right of F.
     - K and B don’t sit at the end.
     - O doesn’t sit adjacent to N and L.

- From statement III:
     - L and K do not sit adjacent to each other.
     - B neither faces N nor sits adjacent to the person who faces N.
     - More than one person sits to the right of D who does not sit adjacent to E.
     - E and F don’t sit at the end.

4. After careful arrangement considering all conditions, the final seating is:

Row 1 (facing south): L, M, K, N, Q, O
   Row 2 (facing north): D, B, F, A, E, C

5. Since persons face each other, the person facing Q is E.
