If Raman has to post a green flag exactly halfway between the line segment joining the two flags, where should he post his flag?

A) 16m on 4th line

B) 16m on 5th line

C) 18 m on 4th line

D) 18m on 5th line

Correct Answer: D

Solution :

Position of green flag = Mid-point of yellow and blue flag.

\[=\left[ \frac{3+7}{2},\frac{20+16}{2} \right]\,\,=\,\,\left[ \frac{10}{2},\frac{36}{2} \right]=(5,18)\]

Hence, Raman should post his green flag at \[\text{18 m}\] on 5th line.

So, option [d] is correct.
