    Direction: What approximate value should come in place of question mark (?) in the question?
    \[(127.998\times 10.012\times \sqrt{6400)}\div 100={{?}^{2}}\]

    A)  34                               

    B)  49                   

    C)  32                   

    D)         28

    E)  38

    Correct Answer: C

    Solution :

    \[{{(?)}^{2}}=(127.998\times 10.012\times \sqrt{6400})\] \[\div 100\] \[\approx \frac{(128\times 10)\times \sqrt{6400}}{100}=\frac{128\times 10\times 80}{100}\] \[=128\times 8=1024\] \[\therefore ?\approx \sqrt{1024}=32\]
