    If \[x:\text{ }y\text{ }=\text{ }7:5,\]then what is \[(5x-2y):\left( 3x+2y \right)\]equal to?

    A) \[\frac{5}{4}\]            

    B) \[\frac{6}{5}\]

    C) \[\frac{25}{31}\]           

    D) \[\frac{31}{42}\]

    Correct Answer: C

    Solution :

    \[\frac{x}{y}=\frac{7}{5}\] \[\frac{5x-2y}{3x+2y}=\frac{5.\frac{x}{y}-2}{3.\frac{x}{y}+2}=\frac{5\times \frac{7}{5}-2}{3\times \frac{7}{5}+2}=\]
