  • Question
  • 6 men can complete a piece of work in 12 days. 8 women can complete the same piece of work in 18 days whereas 18 children can complete the piece of work in 10 days. 4 men, 12 women and 20 children work together for 2 days. If only men were to complete the remaining work in 1 day how many men would be required totally?


  • Options
  • A. 38
  • B. 72
  • C. 36
  • D. 76

  • Correct Answer
  • 36 

    Explanation

    Given 4men, 12 women and 20 children work for  2 days.

    Workdone for 2 days by 4men, 12 women and 20 children =  4   x   2 6   x   12   +   12   x   2 8   x   18   +   20   x   2 18   x   10   =   1 2

    Therefore, remaining work = 1 -  1 2  =  1 2

    To complete the same work by only men in 1 day,

    We know that M1 x D1 = M2 x D2

    Here M1 = 6 , D1 = 12 and M2 = M , D2 = 1

    12 x 6 = M x 1

    => M = 12 x 6 = 72

    => But the remaining work = 1/2

    Men required => 1/2 x 72 = 36

    Only men required to Complete the remaining work in 1 day = 36.
