From the given statements, there are two benches gap between Q and R, who sits at one of the extreme end. Here we get two possibilities i.e. Case 1 and Case 2. D faces to the one who sits exactly between R and Q, who does not sit at the extreme end. There are three persons sit between G and D. There are 5 persons sit between B and E, who sits at one of the extreme end. From the given statements, T sits 2nd to the left of the one who faces to E. Here Case 1 is ruled out now. Both P and M, sit on same bench. More than one person sit between M and T. One person sit between C and D. Here one more possibility is added – Case 2a. There is one bench gap between H and C. H does not face P. A sits 2nd to the left of F.
