- Let 1 man's 1 day's work=x
1 woman's 1 day's work=y
then, 4x+6y=1/8 and 3x+7y=1/10
solving above two,we get x=11/100 and y=1/400
Then,10 women's 1day's work= 1/400*10 = 1/40
So,10women can finish the work in 40/1 = 40 days

- 4x+6y=1/8 and 3x+7y=1/10 therefore y = 1/400
for 10 women means 1/400 * 10 = 1/40
ie, 40 days.. - 9 years agoHelpfull: Yes(0) No(0)
