A) \[\left( \frac{\sqrt{3}-1}{\sqrt{3}+1} \right)\,60\,\,m\]
B) \[\left( \frac{\sqrt{3}+1}{\sqrt{3}-1} \right)\,60\,\,m\]
C) \[\left( \frac{\sqrt{3}+1}{\sqrt{3}-1} \right)\,\,\,m\]
D) None of these
Correct Answer: B
Solution :
Required distance = \[60\cot {{15}^{o}}=60\left( \frac{\sqrt{3}+1}{\sqrt{3}-1} \right)\].
