    The quotient of the cube root of a number and 25 is 5. Identify the number.

    A)  \[{{5}^{3}}\]                                     

    B)                         \[{{25}^{3}}\]                                   

    C)                         \[{{125}^{2}}\]                                 

    D)                         \[{{125}^{3}}\] 

    Correct Answer: D

    Solution :

    According to the problem if ?x? is the number, then \[\sqrt[3]{x}+25\] is 5 \[\Rightarrow \]   \[\sqrt[3]{x}=125\]  \[\Rightarrow \]   \[x={{125}^{3}}\]
