    A)  10                     

    B)  6

    C)  12                   

    D)       24

    Correct Answer: C

    Solution :

     Let be the total work. One man's work \[=1/x\] One day's work of one man \[=1/8x\] One day's work of one man \[=1/(x+4)6\] \[1/8x=1/(x+4)6,(x+4)6=8x\] \[=6x+24=8x\] \[2x=24\]  \[x=12\] Option c is correct.
