    Direction: What approximate value should come in place of question mark (?) in the the question? (You are not expected to calculate the exact value.)
    \[24.8\sqrt{?}+\sqrt{2025}+\sqrt{7225}=152.371\times 8.756\]

    A)  9                                

    B)  6                    

    C)  7                    

    D)       8                    

    E)  11

    Correct Answer: C

    Solution :

    \[24.87\sqrt{?}+\sqrt{2025}+\sqrt{7225}=152.371\times 8.756\] or, \[25\sqrt{?}+45+85\approx 152\times 9=1368\] or, \[25\sqrt{?}\approx 1368-130\] or, \[\sqrt{?}\approx \frac{1238}{25}\approx 49.52\] \[\therefore ?\approx {{(49)}^{\frac{1}{2}}}=7\]
