Question
How many person sit between F and E?
Answer the questions based on the Information given below. Eleven person A, B, C, D, E, F, G, H, I, J and K are sitting in the straight line. Some of them are facing north and some of them are facing south. Not more than two person of immediate neighbour are facing same direction. All the information are not necessarily in the same order. Note: Immediate neighbour 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. Less than three person sit between A and B, who is facing opposite directions of C. Two person sit between F and J. Number of person sit to the left of I as same as number of person sit to the left of C. A sits fifth to the right of one who is second to the right of B. Neither F nor I sits at the extreme end of the row. Two person sits to the right of G, who is facing same directions of A. F sits some where to the left of A. E sits four place away from H and who not facing north. Immediate neighbour of G are facing same directions. E sits to the right of H, who is facing same direction of E. Both extreme end persons are facing opposite directions. G sits three place away from the B and who not immediate neighbour of D. A and B are facing in same direction. E doesn’t sit at any ends.Solution
 Less than three person sit between A and B.  A sits fifth to the right of one who is second to the right of B.  A and B are facing in same direction. Two person sits to the right of G, who is facing same directions of A.  G sits three place away from the B
Neither F nor I sits at the extreme end of the row. F sits some where to the left of A Two person sit between F and J
B, who is facing opposite directions of C. Number of person sit to the left of I as same as number of person sit to the left of C. Case 2 is not valid, because E sits four place away from H and who not facing north. E sits to the right of H, who is facing same direction of E. E doesn’t sit at any ends.
G is not immediate neighbour of D Immediate neighbour of G are facing same directions. Â Both extreme end persons are facing opposite directions. Final arrangements as follows,
