The door of Praveen's house faces east, from the backside of his house, he walks straight 40 meters, then turns to the right and walks 40 meters again. Finally he turns towards left and stops after walking 15 meters. Now Praveen is in which direction from the starting point?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → North-west
The door faces East, so the back of the house faces West, and walking straight out from the backside Praveen walks West. Each turn after that is taken from the direction he is facing at that moment:
He walks 40 m West, so he faces West
Facing West, a right turn is North: he walks 40 m North
Facing North, a left turn is West: he walks 15 m West
He ends \(40+15=55\) m to the West and 40 m to the North of the starting point, so he is to the North-west of it.
