    A)  7 days            

    B)  6 days

    C)  9 days

    D)  3 days

    Correct Answer: B

    Solution :

     \[\because \,\,\,\,\frac{{{M}_{1}}{{D}_{1}}}{{{W}_{1}}}=\frac{{{M}_{2}}{{D}_{2}}}{{{W}_{2}}}\] \[\Rightarrow \,\,\frac{36\times 16}{\frac{2}{3}}=\frac{48\times {{D}_{2}}}{\frac{1}{3}}\] \[\Rightarrow \,\,{{D}_{2}}=\frac{36\times 16}{48\times 2}=\]
