    If \[\frac{x}{y}=\frac{6}{5},\]then \[\left( \frac{6}{7}-\frac{5x-y}{5x-y} \right)\]is equal to

    A)          \[\frac{1}{7}\] 

    B)  \[\frac{2}{7}\]

    C)  \[\frac{3}{7}\]                         

    D)  \[\frac{4}{7}\]

    Correct Answer: A

    Solution :

    Given Expression \[=\frac{6}{7}-\frac{5\left( \frac{x}{y} \right)-1}{5\left( \frac{x}{y}+1 \right)}\] \[=\frac{6}{7}-\frac{\left( 5\times \frac{6}{5} \right)-1}{\left( 5\times \frac{6}{5}+1 \right)}=\frac{6}{7}-\frac{(6-1)}{(6+1)}=\frac{6}{7}-\frac{5}{7}=\frac{1}{7}\]
