Raj is moving towards the west. While walking, he turns right, right and left three times at an angle of 45 degrees at every turn. In which direction is he looking now?
The door of Rohit's house faces east, from the backyard of the house he walks straight 100 yards, then turns right and walks 100 yards and then turns left and stops after walking 50 yards. What is the direction of the place from where Rohit started?
Explanation:
Since the house faces East, the backyard faces West. Rohit walks 100 yards West, turns right (North) for 100 yards, and turns left (West) for 50 yards. He ends up North-West of his house. Therefore, from his final position, the house (starting point) is to the South-East.
