    If \[\frac{a}{3}=\frac{b}{4}=\frac{c}{7},\] then \[\frac{a+b+c}{c}\] is equal to

    A) 0                                 

    B) 1

    C) 2                     

    D) 3

    Correct Answer: C

    Solution :

    \[\frac{a}{3}=\frac{b}{4}=\frac{c}{7}=k\,(Let)\] \[a=3k,\] \[b=4k,\] \[c=7k\] \[\therefore \]      \[\frac{a+b+c}{c}=\frac{3k+4k+7k}{7k}\]             \[=\frac{14k}{7k}=2\]
