• A. 50 m
  
• B. 60 m
  
• C. 40 m
  
• D. Cannot be determined
  
• E. None of these

Answer 1

The correct option is C 40 m


P walked 20 m towards North and took a left turn and walk 10 m.

He took a right turn and walked 20 m and again took a right turn and walk 10 m.

We have to calculate the distance between starting point and end point.
Join AD by dotted lines
OD=OA=AD
=20+20 [AD =BC=20 m]
=40 m
Therefore, P is 40 m far away from the starting point.
