Question
Which of the following statement is correct?
Study the following information carefully and answer the questions given below. Eight persons A, B, C, D, E, F, G and H are sitting in straight line. Some of them are facing north while some of the facing south but not necessarily in the same order. G sits at one of the extreme ends of the line. Only three persons sit between F and G. A sits second to the right of F. Both C and B are facing the same direction. D faces north. E sits to the immediate right of G. C sits third to the right of B. Both F and E face the same direction as A. Only three persons sit between D and H. F sits to the immediate left of D. H is not facing the same direction as G. Both the immediate neighbors of D face opposite directions.Solution
G sits at one of the extreme ends of the line. Only three persons sit between F and G. E sits to the immediate right of G. F sits to the immediate left of D. D faces north. Case-1 Only three persons sit between D and H. H is not facing the same direction as G. C sits third to the right of B. Both C and B are facing the same direction. A sits second to the right of F. Both the immediate neighbors of D face opposite directions. Both F and E face the same direction as A. Hence, case 1 gets eliminated.
