Six persons A, B, C, D, E and F are sitting in a row facing North. A and F are sitting at two extreme ends of the row. B is to the immediate right of A and D is 2nd left of F. What is the position of E with respect to A?
A. E is to the right of A.
B. E is to the left of C.
Which statement is sufficient to answer the question or not.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → If B alone sufficient only
All six face North, so their right is the East end of the row. First fix what the question itself gives:
A and F sit at the two ends, and B is to the immediate right of A, so A is at the left end (place 1), B at place 2 and F at the right end (place 6).
D is 2nd to the left of F, so D is at place 4.
Places 3 and 5 are left for C and E, in either order.
Now the two statements:
Statement A (E is to the right of A) is true for both places 3 and 5, since everyone is to the right of A. Not sufficient.
Statement B (E is to the left of C) puts E at place 3 and C at place 5, so E is third from the left end, second to the right of A. Sufficient.
