A contract is to be completed in 56 days if 104 persons work, each working at 8 hours a day. After 30 days, 2/5 of the work is completed. How many additional persons should be deployed so that the work will be completed in the scheduled time,each persons now working 9 hours a day.

• simple equation is 104*30*8*2/5 = X*26*9*3/5
  => X=160
  => so additional men required are 160-104=56 men
