Show answer & explanation
Correct answer: A
CONCEPT
Facing direction depends only on the sequence of turns; the distances travelled do not change which way a person faces. A right turn moves one step clockwise in the cycle North → East → South → West, while a left turn moves one step anticlockwise.
APPLICATION
Start facing East.
Right turn: East → South.
Right turn: South → West.
Left turn: West → South.
Left turn: South → East.
Left turn: East → North. The distances between turns affect position, not orientation.
CROSS-CHECK
The turns are R, R, L, L, L. Two right turns and two of the left turns cancel, leaving one net left turn from East, which gives North.
Result: the man is facing North.
