Certain number of persons are sitting in a linear row from west to east and facing in the north direction. 
Q sits third from one of the ends. M sits sixth to the right of Q. 
Five persons sit between M and X, who is the neighbour of P.

Y sits exactly between M and Q.

The number of persons sitting between X and Y is equal to the number of persons sitting between X and Z. 

Three persons sit between P and J, who is fifth from one of the ends. Thus, case 2 is invalid. 
Therefore, the final arrangement is: 
 
 
If 'T' sits exactly between J and Z, then T will be thirteenth to the right of M.
