Angel   (12 years ago)

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

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

Sourajit Saha  (8 years ago)

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

AMIT Kumar  (9 years ago)

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

Is this solution Helpfull? Yes | No   

Pratyush Maity  (8 years ago)

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
