Four people W, X, Y and Z sit in a row facing south. W is to the left of X, and Y is to the right of Z. If W is at the extreme left as seen by the reader, where does W sit from W's own perspective?
- A. at W's own extreme right, because facing south reverses left and right
- B. at W's own extreme left
- C. in the middle
- D. cannot be determined
Explanation
A person facing south has east on their left and west on their right, which is the mirror image of the reader's view of a north facing row. So the seat the reader sees as leftmost is the rightmost from the seated person's perspective. Direction of facing is the single most common source of error in these puzzles.
