Pinky walks a distance 600 m towards east, turns left moves 500 m, then again turns left and walks 600 m and then turns left again and moves 500 m and halts. At what distance (in meter) she is from the starting point?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 0
Track the direction Pinky faces after every turn; a left turn moves the facing a quarter turn anticlockwise (East → North → West → South).
600 m East
Turns left, now facing North: 500 m North
Turns left, now facing West: 600 m West, which cancels the 600 m East
Turns left, now facing South: 500 m South, which cancels the 500 m North
She has walked round a rectangle and is back at the starting point, 0 m from it.
