Question
Mr. AP, BP, CP, DP, EP, FP, GP and HP are in a meeting,
sitting around a round table facing the centre. HP is sitting third to the left of EP. DP is sitting second to the left of AP. AP is sitting across HP. BP is a neighbour of HP but not of DP. CP is sitting second to the left of BP. FP does not sit across DP. Who is sitting across DP?Solution
 Mr. HP is sitting third to the left of EP. DP is sitting second to the left of AP.  Since AP is sitting across HP, they are sitting opposite to each other.  Since BP is a neighbor of HP but not of DP, means BP sits to the immediate left of HP.  CP is sitting second to the left of BP.  FP doesn’t sit across DP. Thus, FP sits across CP and GP sits across DP. Final arrangement is shown below: From the above arrangement, it is clear that GP is sitting across DP. Hence, the correct answer is (A).
