The value of ( 0.06 )^2 + ( 0.47 )^2 + ( 0.079 )^2 ( 0.006 )^2 + ( 0.047 )^2 + ( 0.0079 )^2 is :

Answer: Option C

Given expression :
$$=\frac{a^2+b^2+c^2}{{\left(\frac{a}{10}\right)}^2+{\left(\frac{b}{10}\right)}^2+{\left(\frac{c}{10}\right)}^2}$$
Where a = 0.06, b = 0.47 and c = 0.079
$$\begin{array}{rl}& =\frac{100\left(a^2+b^2+c^2\right)}{\left(a^2+b^2+c^2\right)}\\ & =100\end{array}$$
