    A contractor undertook to finish a certain work in 124 days and employed 120 men. After 64 days, he found that he had already done \[\frac{2}{3}\] of the work. How many men can be discharged now so that the work may finish in time?

    A)  48                  

    B)  56

    C)  40                

    D)       50

    Correct Answer: B

    Solution :

     Remaining work \[=1-\frac{9}{3}=\frac{1}{3};\] Remaining days \[=124-64=60\] \[\therefore \]  \[\frac{{{M}_{1}}{{D}_{1}}}{{{W}_{1}}}=\frac{{{M}_{2}}{{D}_{2}}}{{{W}_{2}}}\] \[\Rightarrow \]   \[\frac{120\times 64}{\frac{2}{3}}=\frac{{{M}_{2}}\times 60}{\frac{1}{3}}\] \[\Rightarrow \]               \[{{M}_{2}}=\frac{120\times 64}{2\times 60}=64\] \[\therefore \] Required answer \[=120-64=56\] men
