Discussion
If a boy starting from Nilesh, met to Ankur and then to Kumar and after this he to Dev and then to Pintu and whole the time he walked in a straight line, then how much total distance did he cover?
Answer: A
Correct answer: 215 m
Facing north, a person’s right is east. So Ankur being the reference, Kumar stands 40 m east of him, Dev 60 m south of Kumar, Nilesh 25 m west of Ankur, and Pintu 90 m north of Dev - which puts Pintu 30 m north of the Ankur–Kumar line.
The legs are Nilesh to Ankur 25 m, Ankur to Kumar 40 m, Kumar to Dev 60 m and Dev to Pintu 90 m: \[ 25 + 40 + 60 + 90 = \mathbf{215}\text{ m} \]
