How many persons sit between D and G, if counted from the right of G?

E sits 2nd to the left of F, who faces towards the centre. One person sits between E and B. A sits 4th to the right of B. So, A sits immediate right of F. B faces outside. H sits 2nd to the left of D, who faces towards the centre. G sits 2nd to the left of C, who doesn’t face same direction as B. H doesn’t sit with F. So, H sits 3rd to the right of B or immediate left of B and C sits immediate left of F or 4th to the right of F. Case I: C sits immediate left of F: Case II: C sits 4th to the right of F: I doesn’t sit adjacent to H, so case I is rejected. Immediate neighbors of G face opposite direction to G. So, G must face towards the centre while I and A face outside and H and E face outside. The final seating arrangement is given below:
