    A) 7 days              

    B) 6 days

    C) 5 days  

    D) 4 days

    Correct Answer: C

    Solution :

    \[\overset{\mathbf{Soldiers}}{\mathop{{}_{160}^{100}\mathop{\uparrow }_{{}}^{{}}}}\,\]                  \[\overset{\mathbf{Days}}{\mathop{{}_{x}^{8}\mathop{\downarrow }_{{}}^{{}}}}\,\] \[\Rightarrow \]   \[\frac{160}{100}=\frac{8}{x}\] \[\Rightarrow \]   \[x=\frac{8\times 100}{160}=5\,days\]
