A question is given, followed by two statements

Solution

From statement I alone, F sits immediate right of A. C sits second to the right of A. E sits immediate right of C. B sits immediate left of D. B doesn't sit adjacent to E. B         D         A         F          C         E Here, A sits second to the left of C. So, statement I alone is sufficient to answer the question. From statement II alone, two persons sit between E and A. A sits third from one of the extreme ends of the row. B sits second to the left of A. F sits to the left of C. Case 1: When A sits third from the extreme left end. B         D/F      A         F/D/E              C/D     E Case 2: When A sits third from the extreme right end. E         B         D/F      A         F/C/D  C/D Here, we cannot fix the position of C. So, statement II alone is not sufficient to answer the question. So, data given in statement I alone is sufficient to answer the question while data given in statement II is not sufficient to answer the question .
