    A)  33 days                       

    B)  40 days

    D)  44 days

    Correct Answer: C

    Solution :

     \[\frac{{{M}_{1}}{{D}_{1}}}{{{W}_{1}}}=\frac{{{M}_{2}}{{D}_{2}}}{{{W}_{2}}}\] \[\Rightarrow \]\[\frac{36\times 55}{1}=\frac{66\times {{D}_{2}}}{2}\] \[\Rightarrow \]\[66\times {{D}_{2}}=2\times 36\times 55\] \[\Rightarrow \]\[{{D}_{2}}=\frac{2\times 36\times 55}{66}=60\] days
