Ram starts his journey from point A and walks 100 m in the East direction. Then he turns left and walks 50 m. He again turns left and walks 50 m and again turns left and walks a further 50 m and reaches point C. How far is he now from his initial point A?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 50 m
Each left turn is a quarter turn anticlockwise from the direction he is facing at that moment:
He walks 100 m East.
Left of East is North: 50 m North.
Left of North is West: 50 m West.
Left of West is South: 50 m South, to C.
The 50 m South cancels the 50 m North, so C is on his starting line, and he is \(100-50=50\) m east of A.
