Four friends, A, B, C, and D, sit in a line facing north. B is to the right of A. C is to the left of D. A is not at the end.
Who is at the extreme left end?
Show answer & explanation
Correct answer: C
Explanation
Let the four positions from left to right be 1, 2, 3, and 4 (facing North):
• A is not at either end: A can only be at position 2 or position 3.
• B is to the right of A: A must have at least one position to its right for B.
• C is to the left of D: C must be placed somewhere to the left of D.
Since A is not at position 1 (left end) and B is to the right of A, neither A nor B can be at the extreme left. Between C and D, C is to the left of D, so D also cannot be at the extreme left.
Therefore, C must be at the extreme left end.
Correct Answer: Option (C)
