    C)  6                                

    D)  10

    Correct Answer: D

    Solution :

    \[\overset{\mathbf{Person}}{\mathop{{}_{7}^{5}\mathop{\uparrow }_{{}}^{{}}}}\,\]               \[\overset{\mathbf{Days}}{\mathop{{}_{4}^{8}\mathop{\uparrow }_{{}}^{{}}}}\,\]                 \[\overset{\mathbf{Hours}}{\mathop{{}_{x}^{7}\mathop{\downarrow }_{{}}^{{}}}}\,\] \[\therefore \]      \[\left. \begin{align}   & 7:5 \\  & 4:8 \\ \end{align} \right\}:\,\,:7:x\] \[\Rightarrow \]   \[x=\frac{7\times 5\times 8}{7\times 4}=10\]
