    A)  9 days 

    B)  5 days

    C)  7 days 

    D)  8 days

    Correct Answer: A

    Solution :

    [a] \[\therefore \] 12 men =18 women \[\therefore \] 2 men = 3 women \[\therefore \] 8 men +16 women= 28 women \[\therefore \] \[{{M}_{1}}{{D}_{1}}={{M}_{2}}{{D}_{2}}\] \[\Rightarrow \,\,\,18\times 14=28\times {{D}_{2}}\] \[\Rightarrow {{D}_{2}}=\frac{18\times 14}{28}=9\,\,days\]
