    If \[n+\frac{2}{3}n+\frac{1}{2}n+\frac{1}{7}n=97,\] then the value of n is

    A)  40                               

    B)  42

    C)  44                               

    D)  46

    Correct Answer: B

    Solution :

    \[n+\frac{2n}{3}+\frac{n}{2}+\frac{n}{7}=97\] \[\Rightarrow \]   \[\frac{42n+28n+21n+6n}{42}=97\] \[\Rightarrow \]   \[\frac{97n}{42}=97\] \[\Rightarrow \]   \[n=\frac{97\times 72}{97}=42\]
