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

• 9 days
  
  8 women, 1 day work= 8/(12*18)=1/27
  8 men, 1 day work= 8/(9*12)=2/27
  In 1 day 8 men & 8 women will complete (1/27)+(2/27)=3/27= 1/9
  So the whole work will be completed in 1/(1/9)= 9 days

• 1/((8/18*12)+8/(12*9))=====9

• 1 women work in 1 day= 1/18*12
  1 man work in 1 day = 1/12*9
  8 woman work = 8/18*12
  8 man work =8/12*9
  total work =(8/18*12) + (8/12*9) = 1/9
  means works complete in 9 days
