ans :: 7(3/10)days
let 1 man take M days and 1 boy take B days.
1 day work of a boy=(1/B)
1 day work of a man = (2/B)
12*2/B + 4/B=1/8
so, B=28*8=224
M=112
3(10/112 + 6/224)=39/112 for 3 days
work left=1-39/112=73/112

this will be completed by 4 men and 12 boys.
1 day work of 4 men and 12 boys=4/112 + 12/224=10/112
so , 10/112 work in 1 day
73/112 work in (112/10)*(73/112)=7(3/10)days
