3m+5w=12 days...............>36m+60w=1 work (i) (hint: mens*days =work)
5m+12w=6 days..............>30m+72w=1 work (ii)
from 1 and 2
36m+60w = 30m+72w bcz both efficiencies are same
6m = 12w
1m=2w
from (i) 3(2w)+5w=12
11w can do the wrk in 12 days
1 women work =12*11=132
we have to find out 4m+4w =?
4(2w)+4w=12w
1w work =132
12w work = 132/12=12 days
5m+12w=6 days..............>30m+72w=1 work (ii)
