- 6 times
If 9 women,1 day work= 1/x ---(i)
So 3 men, 1 day work=1/(x-5) ---(ii)
Also given 3 women and 2 men 1 day work= 1/6 ---(iii)
From (i),3 women 1 day work=1/3x
From (ii,2 men 1 day work=2/[3(x-5)]
So (iii) can be represented as, 1/3x + 2/[3(x-5)]= 1/6
Solving x=10
So 1 woman 1 day work=1/(9*10)= 1/90 and
1 man 1 day work=1/3(10-5)= 1/15
Output of a men exceed that of a women = (1/15)/(1/90)= 6 times
