Starting from point P, Sunil walked 30 m towards South. He turned to his left and walked 40 m. Then, he again turned to his left and walked 30 m. Turning again to his left he walks 15 m and stops there at point N. How far is Sunil from starting point P?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 25 m
Each left turn is taken from the direction Sunil is facing at that moment:
Facing South, a left turn is East
Facing East, a left turn is North
Facing North, a left turn is West

The 30 m South and the 30 m North cancel each other, so N is on the same line as P. Sunil went 40 m East and came back 15 m West, so he stops \(40-15=25\) m East of P.
