--------------- and ---------sit adjacent to

Solution

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