Ankit walks 3 km towards the south, turns left and walks 6 km. Then he turns towards north and walks 5 km. Again he turns towards west, walks 4 km and stops for a while. Then he further walks 2 km. How far is he from his starting position?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 2 km
Each turn is taken from the direction Ankit is facing at that moment:
He walks 3 km South. Facing South, a left turn is East: he walks 6 km East
He turns North and walks 5 km
He turns West and walks 4 km, stops, and then walks 2 km more in the same direction: 6 km West in all
Where he ends:
East-West: 6 km East, then 6 km West, so he is back on the North-South line through the start
North-South: 3 km South, then 5 km North, so he ends 2 km North of the start
