    A)  \[\frac{-482}{251}\] 

    B)          9

    C)  \[\frac{-481}{252}\]

    D) All of these

    Correct Answer: C

    Solution :

                                 \[\frac{3}{4}+\frac{5}{9}-\frac{3}{2}\times \,\frac{5}{7}\div \frac{3}{9}\] \[=\frac{3}{4}\,+\frac{5}{9}-\frac{3}{2}\times \frac{5}{7}\,\times \frac{9}{3}\,=\frac{3}{4}\,+\frac{5}{9}-\frac{45}{14}\] \[=\frac{189+140-810}{252}=\frac{-481}{252}\]
