let's say 3 boys = 6 kpowers (kpower is something constant), so 1 boy = 2 kpowers; 
then 2 women = 6 kpowers (because 2 women and 3 boys can do the job in the same amount of time), so 1 woman = 3 kpowers; 
and 1 man = 6 kpowers. 
 
at the next step 1 man + 1 woman + 1 boy = 6 + 3 + 2 = 11 kpowers. 
 
so if 6 kpowers can do the job in 44 days, 11 kpowers can do it in 44*6/11=24
