Six Persons A, B, C, D, E and F are sitting equidistant from each other around a circular table (facing the centre of the table). Consider the Question and two Statements given below: Question: Who is sitting on the immediate left of A? Statement-1: B is sitting opposite to C and D is sitting opposite to E. Statement-2: F is sitting on the immediate left of B. Which one of the following is correct in respect of the Question and the Statements?
  1. Statement-1 alone is sufficient to answer the Question
  2. Statement-2 alone is sufficient to answer the Question
  3. Both Statement-1 and Statement-2 are sufficient to answer the Question
  4. Both Statement-1 and Statement-2 are not sufficient to answer the Question

Solution

Neither statement alone fixes A's neighbours. Combining both still leaves two possible circular arrangements, so the person on the immediate left of A cannot be uniquely determined. Hence both statements together are not sufficient.
