    A person walks a distance in 114 days, when he rests 9 h a day. How long will he take to walk twice the distance if he walks twice as fast and rests twice as long each day as before?

    A) 57 days            

    B) 228 days

    C) 285 days          

    D) 324 days

    Correct Answer: C

    Solution :

    Distance/Speed/Hour per Day/days \[\mathop{_{2}^{1}\downarrow }_{{}}^{{}}\] \[\mathop{\uparrow }_{2}^{1}\]            \[\mathop{\uparrow }_{6}^{15}\]   \[\mathop{\downarrow }_{x}^{114}\]             \[\left. \begin{matrix}    1:2  \\    2:1  \\    6:15  \\ \end{matrix} \right\}14:x\] \[\therefore \] \[1\times 2\times 6\times x=2\times 1\times 15\times 114\] \[\Rightarrow \]   \[x=\frac{2\times 1\times 15\times 114}{2\times 6}\]             \[x=285\,\text{days}\]
