Correct answer
A is the only neighbour of M.
Why this answer is correct
Given: There are three rows, i.e., Row A, Row B, and Row C. Row A is north of Row B and Row B is north of Row C. Four people sit in Row A and Row C each, while eight people sit in Row B. Four persons from the left end of Row B face the persons sitting in Row A, and the remaining four persons face the persons sitting in Row C. Persons sitting in Row A face south, and persons sitting in Row C face north. All persons sit opposite exactly one person.
- The person who sits opposite T sits third to the left of M, who does not face south.
Here, we have 2 Cases, i.e., Case 1 and Case 2.
-
Two people sit between K and T.
-
K does not face north.
-
The person who sits opposite R sits second to the right of K.
-
As many persons sit between R and M as between P and J.
-
J does not face north and does not sit in Row B.
-
P does not sit at any extreme end.
Now, we can eliminate Case 2 and have a subcase of Case 1.
-
The person sitting opposite to P sits fourth to the right of D.
-
Three people sit between D and H.
-
As many persons sit to the right of H as to the left of V in the same row.
-
S and N are immediate neighbours, but neither of them faces south.
-
S is not an immediate neighbour of T and H.
Now, we can eliminate Case 1a.
- X sits opposite C, who does not sit in Row B.
- F does not face north.
- The number of persons sitting between X and H is one less than the number of persons sitting to the right of A.
- A does not face south.
- K does not face E.
This is our final arrangement,
Hence, the correct answer is A is the only neighbour of M.
