group? Answer the questions based on the information given below. Nine person A, B, C, D, E, F, G, H and I are sitting in the straight line but necessarily in the same order. Some of them are facing north and some of them are facing south. All of them are of different heights i.e.; each person is taller than or shorter than another person. Note: Immediate neighbours are opposite direction means one person is facing north while another person is facing south. If same direction means one person is facing north while another is also facing north and vice versa. The third tallest person sits third to the left of E, who is shorter than D and taller than A. The tallest person is immediate neighbour of the person, who is taller than G. D is not the immediate neighbour of C. G is facing south. G is shorter than I but taller than B, who is not the shortest person. E is one place away from one of the extreme ends and shorter than C, who is shorter than two person. Not more than two person are facing the same direction in the continuous manner. The second shortest person sits four place away from E. I is shorter than D, who is facing south but taller than E. Three person sit between C and A, who is taller than B and F and A sits to the left of C. Neither F nor A is the shortest person. G is taller than A but shorter than E and is second to the right of B. Neither G nor D sits in the extreme end of the row. E and F, who is taller than only H, are facing the same direction. F is facing opposite direction of G. Immediate neighbours of G are facing opposite direction. The second tallest person sits third to the right of C, who is facing opposite direction of E. Both extreme end persons are facing opposite direction.Solution
The third tallest person sits third to the left of E, who is shorter than D and taller than A. E is one place away from one of the extreme end and shorter than C, who is shorter than two person. The second shortest person sits four place away from E. Â Â Â Â Â Â Â Â Â Â Â Â Â Â > > C Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â D > E > A 
G is shorter than I but taller than B, who is not the shortest person. I is shorter than D, who is facing south but taller than E. > > C D > I > E > A I > G > B 
Neither F nor A is the shortest person. F, who is taller than only H, D > I > C > E > G > A > B > F > H 
The tallest person is immediate neighbour of person, who is taller than G. G is facing south. G is taller than A but shorter than E and is second to the right of B. Neither G nor D sits in the extreme end of the row.
