    Given that \[\frac{-6p-9}{3}=\frac{2p+9}{5},\] find the value of 'p'.

    A)  \[-4\]                   

    B)                         \[-2\]                   

    C)                         \[3\]                                    

    D)                         \[5\]                    

    Correct Answer: B

    Solution :

     \[\frac{-6p-9}{3}=\frac{2p+9}{5}\] On cross multiplying, we get \[5(-6p-9)=3(2p+9)\]                 \[\Rightarrow \]        \[p=-\frac{72}{36}=-2\]                 \[\Rightarrow \]               \[p=-2\]
