    Which is the correct order for a given number a in increasing order?

    A) \[{{\log }_{2}}\alpha ,\,\,{{\log }_{3}}\alpha ,\,\,{{\log }_{e}}\alpha ,\,\,{{\log }_{10}}\alpha \]

    B) \[{{\log }_{10}}\alpha ,\,\,{{\log }_{3}}\alpha ,\,\,{{\log }_{e}}\alpha ,\,\,{{\log }_{2}}\alpha \]

    C) \[{{\log }_{10}}\alpha ,\,\,{{\log }_{e}}\alpha ,\,\,{{\log }_{2}}\alpha ,\,\,\alpha {{\log }_{3}}\alpha \]

    D)  None of the above

    Correct Answer: B

    Solution :

    Since,\[10,\,\,3,\,\,e,\,\,2\]are in decreasing order. \[\therefore \]\[{{\log }_{10}}\alpha ,\,\,{{\log }_{3}}\alpha ,\,\,{{\log }_{e}}\alpha ,\,\,{{\log }_{2}}\alpha \]are   in increasing order.
