A girl is facing south-east. She turns 900 degrees clockwise, then turns left, then right once, then right once, then 45 degrees clockwise, and then 135 degrees counterclockwise, and then 45 degrees clockwise. Lastly, in which direction is he facing?
A student starts from his house in south direction, then turns to his right, walks 2 km and turns to his left and again turns to his left and walks 2 km. He now takes 450 turns in clockwise direction and reaches his college. In which direction is his college with respect to his house?
Explanation:
Walks South. Right (West) for 2km. Left (South) then Left (East) for 2km. The 2km West and 2km East cancel out, leaving him directly South of his house. The 450° CW turn (which is one full 360° circle + 90°) only changes the direction he is *facing*, not his geographical position. He remains South of his house.
