SITS fourth to the right of M and Neither M nor P sit at the extreme END of the line. So there are two places between M and P; so two possibilities arise as shown below:R sits second to the left of I and only one person sits between R and K. Neither R nor K is an immediate neighbour of P. Applying the conditions in both possibilities:Only two people sit between I and L and this eliminates the possibility 1 because there is no PLACE for these two as PER condition. So possibility 2 BECOMES as follows:J is not an immediate neighbour of L. So only one position for J is left i.e. between R and I and hence N is automatically filled at its place. Hence final arrangement is as follows:5th from left is I and 6th from right is R. So J is the person sits exactly between R and I.
