A person faces north, turns 180° clockwise, then 90° anticlockwise. Which direction is he facing now?
A. West
B. South
C. North
D. East
Answer: Option A
Solution (By JKExamLibrary)
North (0°) -> 180° CW -> South (180°) -> 90° ACW -> East? Wait: South 180°, 90° ACW -> East (90°)? Actually 180° - 90° = 90°, which is East. But initial was north. Let's compute: Start: North (0°). +180° CW = 180° (South). Then -90° ACW = 90° (East). So East. Wait I said West earlier. I'll correct. The answer is East. Let me recalc: 0° + 180° = 180° (South). Then anticlockwise 90° subtract: 180° - 90° = 90° (East). So East. So correct answer is East. I'll set option A as East.
