18 women complete a work in 12 days and 12 men can complete the same work in 9 days.in how many days will 8 emn and 8 women complete the work?

• 9 days....
  
  1 man's 1day work=1/(9*12)
  8 men's 1 day work=8/(9*12)=2/27
  
  1 woman's 1 day work=1/(12*18)
  8 women's 1 day work=8/(12*18)=1/27
  
  total work by 8 mwn and 8women in 1 day = 1/27+2+27=1/9
  therefore 8 women and 8men can complete the work in 9 days
