A, B, C, D, E, and F are sitting at a circular table facing the centre (not necessarily in the same order). A is to the immediate left of B, E is third to the right of B, D is to the immediate right of C. F is third to the right of C. Who are the immediate neighbours of E? a)A and B b)B and D c)D and F d)F and B
Fix the position of a known person first (e.g., B) and place others based on relative directional cues to create a circular sequence.
Fix the position of a known person first (e.g., B) and place others based on relative directional cues to create a circular sequence.
Establish the anchor positions
Let us place B at position 1. Since A is to the immediate left of B, A is at position 6 (assuming clockwise). Given E is 3rd to the right of B, counting clockwise from B(1), B(2), B(3), B(4), we place E at position 4.
Place remaining individuals
We have positions 2, 3, and 5 vacant. D is immediate right of C. F is 3rd to the right of C. If we place C at 2, then D is at 3. F would then be 3rd to the right of C (2 тЖТ 3, 3 тЖТ 4, 4 тЖТ 5), so F is at 5. All positions filled: 1:B, 2:C, 3:D, 4:E, 5:F, 6:A.
Identify neighbours of E
E is at position 4. The person to the left (clockwise) is D (position 3) and the person to the right (counter-clockwise) is F (position 5). Thus, E's neighbours are D and F.
A is incorrect as A and B are not neighbours of E. B is incorrect as B is at position 1, not adjacent to E at 4. D is incorrect as B is not adjacent to E.
B is correct because the arrangement confirms D and F are sitting on either side of E.
In circular puzzles, always represent the positions as 1 to N in a clock-face style to avoid confusion between left and right directions.
