A, B, C, D, E, F, G and H are sitting around a square table, four of them sit at four corners while four sit at the middle of the sides. The one who sit at the corners face the centre while who sit at the middle face outside.
(i) B sits third to the left of D.
(ii) H sits second to the left of B and G sits third to the left of H.
(iii) Cis an immediate neighbour of B but not an immediate neighbour of H.
(iv) F is an immediate neighbour of D. E doesn't sit at corner.
(V) F.doesn't sit at the corner of the square table.

Explanation

Step I: In this arrangement four persons sit at four corners while four sit at the middle of the sides. The one who sit at the corners face the centre while who sit at the middle face outside. Now, from (v) F doesn.t sit at the corner of the square table, So F will sit at the middle side of the table. From (iv), F is an immediate neighbour of D. There will be two possible places of D which are shown below

Step II: From (i), B sits third to the left of D. From (ii), H sits second to the left of B and G síts third to the left of H. From this case:1 will get eliminated as there is no place of H. Now, proceeding with case : 2

Step III:From (ili), C is an immediate neighbour of B but not an immediate neighbour of H. So, C will sit opposite of D. From (iv), E doesn.t sit at corner. So, E will sit at the middle side of the table.

Step IV:Remaining A will sit at the corner. So, the final arrangement is-
