Correct Answer: 1.5 days
Solution:
9 men can complete the work in (6*6)=36 hours
9 men 1hr work =1/36 then
3 men 1 hr work=1/36*1/3=1/108
given the work done by women in 4 hrs is equal to the work done by man in 3 hrs and by boys in 6 hrs
12 men,12 women and 12 boys 1 hours work is 4/108+3/108+2/108=9/108
they finish the work in 108/9=12hrs
number of days of 8 hours =12*1/8=1.5 days
