Correct Answer: $\frac{5+\sqrt{3}}{2 \sqrt{3}}$
Solution :
Given: $\sin 30^{\circ}+\cos 30^{\circ}+\tan 30^{\circ}$
Putting the values, we get:
$=\frac{1}{2}+\frac{\sqrt3}{2}+\frac{1}{\sqrt3}$
$=\frac{\sqrt3+3+2}{2\sqrt3}$
$=\frac{5+\sqrt3}{2\sqrt3}$
Hence, the correct answer is $\frac{5+\sqrt3}{2\sqrt3}$.
