Saurabh walks 80 meters towards south. Then, turns to his right & starts walking straight till he completes another 80 meters. Then, again turning to his left he walks for 60 meters. He then turns to his left & walks for 80 meters. How far is he from his initial position?

He walks $80$m South, then turns to his right to walk $80$m West. He then turns left to walk $60$m South again, and then turns left to walk $80$m East, which cancels out the $80$m he walked towards the West previously. Hence, he is $80+60=140$m South from his initial position.
