    Step-by-step explanation:

    a:b=5:9 and b:c=6:11; Then Find a:c

    [A]11:34

    [B]10:33

    [C]12:33

    [D]None of these

    10:33

    \because a:c=\frac{a}{c}=\frac{a}{b}\times \frac{b}{c}

    => \frac{5}{9}\times \frac{6}{11}=\frac{10}{33}

    => \frac{a}{c}=\frac{10}{31}

    => a:c=10:31

    Hence option [B] is the right answer.
