Who among the following sits at the corner?

Validate

Solution:

Only three persons sit between M and N and N is sitting at one of the ends. So we get 2 cases –
Case 1:

N				M

Case 2:

			M				N

⇒ O is 2nd to the right of M and facing north. Q is 3rd to the right of O.
Case 1:

N		O		M	Q
		North		South

Case 2:

	O		M	Q			N
	North		South

⇒ More than two persons sit between Q and R. T is 2nd to the left of R.
Case 1:

N	R	O	T	M	Q
	South	North		South

Case 2:

R	O	T	M	Q			N
South	North		South

⇒ More than two persons sit between T and N. So case 1 gets rejected.
P is 2nd to the right of Q. So Q is facing north. M’s neighbours are facing same direction. So T is facing north. Q’s neighbours are facing same direction so S is facing south.P’s neighbours are facing opposite directions. So N is facing north. Four of them are facing north so P is facing south.
Here is the final arrangement:

R	O	T	M	Q	S	P	N
South	North	North	South	North	South	South	North

R is sits at the corner.
So, option A.
