    The ratio of work done by 25 women to work done by 20 men in the same time is 4:5. If 8 men and 10 women can finish the work in 5 days, then how many women can finish the work in 3 days?

    A)  32                               

    B)  40                   

    C)  48                   

    D)         64

    E)  72

    Correct Answer: B

    Solution :

    Ratio of efficiency of one woman to one man \[=\frac{4}{25}:\frac{5}{20}=16:25\] \[\Rightarrow 16men=25women\] \[\therefore \] 8 men + 10 women\[=\frac{25}{2}+10\] = 22.5 women Now, using \[{{M}_{1}}{{D}_{1}}={{M}_{2}}{{D}_{2}}\] Now, \[22.5\times \frac{16}{3}=x\times 3\] \[\therefore x=\frac{22.5\times 16}{9}=40\]
