Who is second to the left of

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.                 > > C                 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. Note: G faces south in case 2 Case 2 is not valid, because D is not the immediate neighbour of C. E and F, who is taller than only H, are facing same direction. The second tallest person sits third to the right of C, who is facing opposite direction of E. Not more than two person are facing same direction in the continuous manner.  F is facing opposite direction of G. Immediate neighbour of G are facing opposite direction.  Both extreme end person are facing opposite Direction Hence, final arrangements  D > I > C > E > G > A > B > F > H Note: The persons sitting in the extreme ends are facing opposite directions. So, A is facing south direction.
