    If \[\frac{7}{8}\times \frac{3}{5}\div 2\frac{x}{8}=03.2,\]then the value of x is

    A)  2                    

    B)  3

    C)  4                    

    D)  None of these

    Correct Answer: D

    Solution :

    \[\because \,\,\,\,\,\frac{7}{8}\times \frac{3}{5}\div \frac{16+x}{8}=0.2\] \[\Rightarrow \]   \[\,\frac{7}{8}\times \frac{3}{5}\times \frac{8}{16+x}=0.2\] \[\Rightarrow \]   \[16+x=\frac{7\times 3\times 8}{8\times 5\times 0.02}=21\] \[\Rightarrow \]               \[x=21-16=5\]
