Solution (By JKExamLibrary)
Path: 5m East, 4m South (right), 5m West (right). He is now 4m South of start. Then he turns left (South) for 20m (total 24m South), then right (West) for 20m. Final position is 20m West and 24m South of the starting point, which is South-West.
Explanation:
N left 90° = West, right 180° = East? Wait: West (270°) + 180° = 90° East? Actually 270°+180°=450°=90° East. So East. Option B. I'll recalc: North -> left 90° -> West. Then 180° right from West: West (270°) +180° clockwise = 450° mod 360 = 90° East. So East. Answer East.
