15 women or 10 men complete in 55 days..how many days 4 women and 5 men vil take

• 1 women 1 day work=1/15*55=1/825
  1 men 1 day work= 1/10*55
  4 women and 5 men 1 day work=(4*1/825)+(5*1/550)=23/1650
  so, 4 women and 5 men can complete work in 1650/23=71 16/23 days
  
  is 42 1/6

• 10 men= 15 women
  5 men= 15/2 women
  now,4 women and 5men
  4women + 15/2 women
  23/2 women
  (4women &5men = 23/2women) can complete a work in = (55*15*2)/23=71.739 days

• 1 Women= 10/15 Men
  4 women= 4*10/158=8/3
  total= 5+8/3 men= 23/3
  chain rule
  
  55*10 = (23/3)*D
  D= 550*3/23 =71.73 days

• 1 woman's work w an for man let it m
  15/w =55
  w=15*55
  10/m=55
  m=10*55
  now put these value in 4/w + 5/m
  then find the (ans)^(-1)

• Here, 15 women==10 men
  so,5 women=10/3=3.33 men
  now total 4 men+5 women==4+3.33=7.33 men
  
  and here, 15*55 women-days==10*55 men-days
  so the no of days =10*55 men-days/7.33 days=75 days

• work of 1w=55/15 ; 1m=55/10
  so
  4w + 5 m= 55(8+15)/30
  ans 42 days

• 15->55days,10->55 days
  1 woman in 1 day=1/15*55, 1 men in 1 day=1/10*55
  suppose no of days=x
  x*(4/(15*55)+5/(10*55))=1
  x=71.73

• 15 women in 55 days can do 1 work
  so,
  1 women in 1 day can do 1/825 of a work
  5 women in 1 day can do 1/825*5=1/165 of a work
  same as,
  4 women in 1 day can do 2/275 of the work
  so ,
  in 1 day 1 women and 1 man can do (1/165+2/275)=1/75
  So,
  1/75 of a work can do in 1 day
  1 of a work can do in 1*75/1= 75 days
