Question

Eight people are sitting in two parallel rows containing 4 people each in such a way that there is equal distance between adjacent persons.

In row 1, D, A, N and S are seated and all of them are facing south.

In row 2, M, O, R and K are seated and all of them are facing north.

Thus, each person faces another person from the other row.

No one sits to the right of K. Only two people sit between R and K. The one facing O sits second to the right of the one facing K. A sits to the immediate right of S. N sits to the immediate right of A and does not face O. Which of the following represents both people facing each other?

• A. A and O
• B. N and O
• C. R and S
• D. D and M

Answer 1

Answer:

A. A and O

Let’s solve it step by step.

We have two rows:

• Row 1 (facing south): D, A, N, S

• Row 2 (facing north): M, O, R, K

Positions: 1 2 3 4 (left to right from our view)

Place K

“No one sits to the right of K”
→ K is at position 4 (extreme right in Row 2)

Place R

“Only two people sit between R and K”
→ With K at 4, R must be at position 1

Row 2:
1 R | 2 | 3 | 4 K

Use facing condition

“The one facing O sits second to the right of the one facing K”

• Person facing K is in Row 1, position 4

• Second to the right (since they face south → right is our left)
  → position 2 in Row 1 faces O

So:

• Row 2 position 2 = O

Row 2 now:
1 R | 2 O | 3 _ | 4 K

Fill remaining in Row 2

Only M left → position 3

Row 2:
1 R | 2 O | 3 M | 4 K

Arrange Row 1

“A sits to immediate right of S” (they face south → right is our left)

So: A is just left of S

“N sits to immediate right of A”
→ N is left of A

So sequence (left to right from our view):
N A S

Possible placement: positions 1,2,3

Remaining D at position 4

Row 1:
1 N | 2 A | 3 S | 4 D

Check condition

“N does not face O”

• N at position 1

• Faces R → OK

  Final arrangement:

Row 1 (South):
N | A | S | D

Row 2 (North):
R | O | M | K

Facing pairs:

• N ↔ R

• A ↔ O

• S ↔ M

• D ↔ K

• Final Answer:

A and O (one correct facing pair)
