Ali, Bob, Carol, Dave, Elma and Frank are sitting around a circular table facing the centre. Ali sits second to the left of Bob. Carol sits third to the right of Bob. Dave sits to the immediate left of Carol. Elma sits to the immediate left of Bob. How many people sit between Elma and Frank when counted from the right of Elma?
Two
Zero
One
Three
One
Fix the reference point (Bob) first. Clockwise (facing center): Left is clockwise, Right is anti-clockwise. Map positions 1 to 6 and count from the target's right (anti-clockwise).
Fix the reference point (Bob) first. Clockwise (facing center): Left is clockwise, Right is anti-clockwise. Map positions 1 to 6 and count from the target's right (anti-clockwise).
Establish Reference
Place Bob at the top (12 o'clock). Elma is to the immediate left of Bob. Since they face the center, 'left' for them is clockwise. So, Elma is at roughly 10 o'clock.
Place remaining members
Ali sits second to the left of Bob (at 2 o'clock). Carol sits third to the right of Bob (Right is anti-clockwise, so Carol is at 6 o'clock). Dave is to the immediate left of Carol (5 o'clock).
Final positioning
Frank takes the only remaining spot at 4 o'clock. Arranging clockwise: Bob (12), Elma (10),?, Carol (6), Dave (5), Frank (4), Ali (2). Counting right from Elma (anti-clockwise), the order is Elma тЖТ Bob тЖТ Ali тЖТ Frank. Between Elma and Frank, only Ali sits.
A: Incorrect; count is 1. B: Incorrect; count is 1. D: Incorrect; count is 1.
C is correct because there is only one person, Ali, sitting between Elma and Frank when counting from the right side of Elma.
In circular puzzles, always determine 'Left' vs 'Right' based on the center-facing orientation; clockwise = Left, anti-clockwise = Right.
