    \[\frac{{{(0.05)}^{2}}+{{(0.41)}^{2}}+{{(0.073)}^{2}}}{{{(0.005)}^{2}}+{{(0.041)}^{2}}+{{(0.0073)}^{2}}}\]is

    A) 10

    B)  100

    C)  1000

    D)  None of these

    Correct Answer: B

    Solution :

    Let a = 0.05, b = 0.4 and c = 0.073 \[\therefore \]\[\frac{{{(0.05)}^{2}}+{{(0.41)}^{2}}+{{(0.073)}^{2}}}{{{(0.005)}^{2}}+{{(0.041)}^{2}}+{{(0.0073)}^{2}}}\] \[=\frac{{{a}^{2}}+{{b}^{2}}+{{c}^{2}}}{{{\left( \frac{a}{10} \right)}^{2}}{{\left( \frac{b}{10} \right)}^{2}}+{{\left( \frac{c}{10} \right)}^{2}}}=\frac{{{a}^{2}}+{{b}^{2}}+{{c}^{2}}}{\frac{1}{100}({{a}^{2}}+{{b}^{2}}+{{c}^{2}})}\] \[\frac{({{a}^{2}}+{{b}^{2}}+{{c}^{2}})\times 100}{{{a}^{2}}+{{b}^{2}}+{{c}^{2}}}=100\]
