A men starts from home, drives 3 km towards North, takes a left turn and drives for 7 km. He then takes a left turn and drives for 10 km before taking a left turn again and driving for further 7 km. The men finally takes a left turn and drives 2 km before stopping. How far and towards which direction should the men drive to reach the home again?
Required distance = 10 – (3 + 2) = 5 Km
