What is the value of $$\frac{{\sqrt {29.16} }}{{\sqrt {1.1664} }} + \frac{{\sqrt {0.2916} }}{{\sqrt {116.64} }} + \frac{{\sqrt {0.0036} }}{{\sqrt {0.36} }}\,?$$
A. $$\frac{{101}}{{20}}$$
B. $$\frac{{103}}{{20}}$$
C. $$\frac{{26}}{5}$$
D. $$\frac{{27}}{5}$$
Answer: Option B
Solution(By Examveda Team)
$$\eqalign{ & \frac{{\sqrt {29.16} }}{{\sqrt {1.1664} }} + \frac{{\sqrt {0.2916} }}{{\sqrt {116.64} }} + \frac{{\sqrt {0.0036} }}{{\sqrt {0.36} }}\, \cr & = \frac{{5.4}}{{1.08}} + \frac{{0.54}}{{10.8}} + \frac{{0.06}}{{0.6}} \cr} $$\[\left[ \begin{gathered} \because \sqrt {294} = 54 \hfill \\ \sqrt {11664} = 108 \hfill \\ \sqrt {36} = 6 \hfill \\ \end{gathered} \right.\]
$$\eqalign{ & = \frac{{540}}{{108}} + \frac{{54}}{{1080}} + \frac{6}{{60}} \cr & = 5 + \frac{1}{{20}} + \frac{1}{{10}} \cr & = \frac{{103}}{{20}} \cr} $$
