Only two persons are sitting between M and R. Only five persons are sitting between R and J. J sits fourth to the right of P. P sits to the right of R. From the above condition, there are two possibilities. Again we have, The number of persons sitting between R and P is one less than between J and X. From the above condition, there are three possibilities.
Again we have, The number of persons sitting between M and J is one more than between M and E. J and E do not sit adjacent to each other. T sits fourth to the right of X. Not more than three persons are adjacent to each other. From the above condition, case2 gets eliminated.
Again we have, The number of persons sitting between J and T is one more than between N and O. O sits third to the right of G. The one who sits immediate right of N sits eighth to the left of the one who sits third to the left of R. O sits to the left of E. More than four persons are sitting between G and E. From the above condition, case1a gets eliminated. Case1 shows the final arrangement.
