    If 12 men or 18 women can do a work in 14 days, then in how many days will 8 men and 16 women do the same work?

    A)  12 days           

    B)  10 days

    C)  14 days           

    D)  9 days

    Correct Answer: D

    Solution :

    12 M = 18 W \[\Rightarrow \,\] \[\,8\,\,M=\frac{18}{12}\times 8=12\,\,W\] \[\therefore \,\,\,\]\[8M+16W=12W+16W=28W\] \[\therefore \,\,\,\]            \[\,18\times 14=28\times {{D}_{2}}\] \[\Rightarrow \,\] \[{{D}_{2}}=\frac{18\times 14}{28}=9\]days.
