    If \[\frac{a}{b}=\frac{2}{3}\]and \[\frac{b}{c}=\frac{4}{5},\]then the ratio \[\frac{a+b}{b+c}\]equal to

    A)  \[\frac{20}{27}\]          

    B)  \[\frac{27}{20}\]

    C)  \[\frac{6}{8}\]

    D)  \[\frac{8}{6}\]

    Correct Answer: A

    Solution :

    \[\frac{a}{b}=\frac{2}{3}=\frac{8}{12},\frac{b}{c}=\frac{12}{15}\] \[\therefore \] Required ratio \[=\frac{8+12}{12+15}=\frac{20}{27}\]
