    If 50% of \[(p-q)\]=30% of (p + q), then p : q is equal to     

    A)                                5 : 3     

    B)  4 : 1   

    C)  3 : 5    

    D)  1 : 4

    Correct Answer: B

    Solution :

    \[\frac{50}{100}(p-q)=\frac{30}{100}(p+q)\] \[\Rightarrow \]\[5\,\,(p-q)=3(p+q)\]\[\Rightarrow \]\[5p-5q=3p+3q\] \[\Rightarrow \]\[2p=8q\]\[\Rightarrow \]\[p=4q\] \[\therefore \]\[p:q=4:1\]
