Question
Four of the following five are alike in a certain way
and hence form the group. Which of the following ones does not belong to the group? Study the following information carefully and answer the below questions. Eight people D, T, O, L, J, A, C, and G are seated around the circular table. All the persons are facing towards the table but not necessarily in the same order. D sits three places away from O who sits second to the right of C. A sits second to the left of T. Neither O nor D is an immediate neighbour of T. The number of persons who sit between L and O is one less than the number of persons who sit between G and J when counted from the right of G and L. L doesn’t sit next to O.Solution
D sits three places away from O who sits second to the right of C 
A sits second to the left of T. Neither O nor D is an immediate neighbour of T. so case-1 is eliminated 
The number of persons who sit between L and O is one less than the number of persons who sit between G and J when counted from the right of G and L. L doesn’t sit next to O.
