    Direction: What approximate value should come in place of question mark (?) in the question?
    \[\sqrt{530}-{{3.99}^{2}}=\sqrt{?}-\sqrt{9.01}\]

    A)  125                 

    B)         120                 

    C)  100                 

    D)         81                   

    E)  64

    Correct Answer: C

    Solution :

    \[\sqrt{?}-\sqrt{9.01}=\sqrt{530}-{{(3.99)}^{2}}\] Or, \[\sqrt{?}\approx 23-{{(4)}^{2}}+\sqrt{9}=23-16+3=10\] Or, \[\sqrt{?}\approx 10\] \[\therefore ?\approx 10\times 10=100\]
