From this we can draw following result :-

As per the given above question , we have
P, Q, R, S, T, V and W are sitting in a straight line facing north. Each one of them lives on a different floor in the same building which is numbered from one to seven. Q sits fourth to the left of the person living on the 6th floor. Either Q or the person living on the 6th floor sits at the extreme ends of the line.
From above it is clear that Q person live on the 6th floor .

_ > _ > _ > _ C > A, E ...........(i)
B > D > _ > _ > _ > _ ...........(ii)
Since E did not score the least, we get B > D > F (81) > C > E (62) > A
is the correct answer; B's score is maximum according to above sequence. F has scored 81 marks. Then B's score = 81 + 13 = 94 marks and D is between B and F. D is most likely to score 89 marks.
