    Given that \[\sqrt{13}=3.6\] and \[\sqrt{130}=11.4,\] then the value of \[\sqrt{1.3}+\sqrt{1300}+\sqrt{0.013}\] is equal to

    A) 36.164             

    B) 37.254

    C) 36.254             

    D) 37.154

    Correct Answer: B

    Solution :

    \[\sqrt{13}=3.6\] and \[\sqrt{130}=11.4\] \[\therefore \]      \[\sqrt{1.3}+\sqrt{1300}+\sqrt{0.013}\]             \[=\sqrt{\frac{130}{100}}+\sqrt{13\times 100}+\sqrt{\frac{130}{10000}}\]             \[=\frac{11.4}{10}+3.6\times 10+\frac{11.4}{100}\]             \[=1.14+36+0.114\]             \[=37.254\]
