    What is the value of \[\frac{725\times 725\times 725+371\times 371\times 371}{725\times 725-725\times 371+371+371\times 371}?\]

    A)  9610               

    B)  1960

    C)  1096   

    D)  1016

    Correct Answer: C

    Solution :

    \[\frac{725\times 725\times 725+371\times 371\times 371}{725\times 725-725\times 371+371\times 371}=725+371\] \[\left( \because \frac{{{a}^{3}}+{{b}^{3}}}{{{a}^{2}}-ab+{{b}^{2}}}=\frac{(a+b)({{a}^{2}}-ab+{{b}^{2}})}{({{a}^{2}}-ab+{{b}^{2}})} \right)=1096\]
