John, Kate, Lisa, Mary, Neil and Omar are sitting around a circular table facing the centre. John sits second to left of Kate. Lisa sits third to right of Kate. Mary sits to the immediate left of Lisa. Neil sits to the immediate right of Kate. How many people Sit between Omar and Mary when counted from the right of Omar?
One
Three
Zero
Two
Two
Fix the position of a known person (e.g., Kate) and place others relative to her. Counting from the right of Omar is simply counting anticlockwise in a clockwise-facing table.
Fix the position of a known person (e.g., Kate) and place others relative to her. Counting from the right of Omar is simply counting anticlockwise in a clockwise-facing table.
Establish Reference
Fix Kate at the top of the circle. Since all face the center, their left is clockwise and their right is anticlockwise.
Placement based on clues
1. John is second to left of Kate: John is at the position 120 degrees clockwise from Kate. 2. Neil is immediate right of Kate: Neil is 60 degrees anticlockwise from Kate. 3. Lisa is third to right of Kate: Lisa is 180 degrees from Kate (opposite). 4. Mary is immediate left of Lisa: Mary is 60 degrees clockwise from Lisa.
Final Positioning
The order clockwise is: Kate тЖТ Neil тЖТ Lisa тЖТ Mary тЖТ Omar тЖТ John. Counting from the right of Omar (anticlockwise): The seats to his right are John, Kate, and Neil. That makes 3 people between Omar and Mary.
A: One is incorrect as it ignores the positions of John, Kate, and Neil. B: Three is the calculated number of seats between Omar and Mary from the right. C: Zero is incorrect as they are not adjacent. D: Two is incorrect as it misses one person in the count.
D is correct because by mapping the circle correctly (Kate at 12 o'clock, Neil at 10, John at 2, Lisa at 6, Mary at 4, Omar at 8), counting right from Omar (anticlockwise) reveals John, Kate, and Neil occupy the three seats before reaching Mary.
In circular puzzles with people facing the center, always remember: Left = Clockwise, Right = Anticlockwise. Draw the circle first to avoid confusion.
