Solution (By JKSSB Mock Tests)
Sam walks 10 m West, then turns left (South) for 5 m, turns left (East) for 10 m (aligning horizontally with his house), and turns left (North) for 10 m. He ends up 5 m North of his starting point.
Gaurav comes out of the back door of his house whose main door is facing north and walks 25m straight, then he turns left and walks 36m, he again turns left and walks 47m. He again turns left and walks 36m. How far and in which direction is he from his house now?
Explanation:
Main door faces north, so back door faces south. Path: 25 m south, left (east) 36 m, left (north) 47 m, left (west) 36 m. Net displacement: north 47 - south 25 = 22 m north; east 36 - west 36 = 0. So he is 22 m north of his house.
