Answer:
I think it is 9 days.
Step-by-step explanation:
1 man can complete the work in 12*7 = 84 days
1 woman in 18*7 = 126
so in 1 day, 1 man can do 1/84 of the work and woman 1/126
Son finish the same task by 4 men and 8 women wld take
x*(4/84+8/126)=1
x*(1/21+4/63)=1
x*(7/63)=1
x=63/7
x=9
So the task can b done by 4 men & 8 women in 9 in days
