    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 :

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