A person walks 10m North, turns right and walks 20m. He then turns right and walks 5m. He again turns left and walks 10m. He then turns left and walks 5m. Finally, he turns right and walks 10m. In which direction is he from his starting point?
Correct: C
Let the starting point be (0,0).
1. Walks 10m North: (0, 10).
2. Turns right (East) and walks 20m: (20, 10).
3. Turns right (South) and walks 5m: (20, 5).
4. Turns left (East) and walks 10m: (30, 5).
5. Turns left (North) and walks 5m: (30, 10).
6. Turns right (East) and walks 10m: (40, 10).
His final position is (40, 10). This position is to the North-East of his starting point (0,0).
