11.66 is ans
15m in 8days , 18w in 12days , 16c in 20days
1m complete wrk in 120days , 1w in 216days , 1c in 320days
12w and 8c complete the work in 360/29 days
So in 10 days they complete 29/36 wrk
Remaining wrk is 7/36
1m complete 1 work in 120days
1m complete 7/36 work in 70/3 days
So x men complete 7/36 work in 2 days
X= 70/6 = 11.66 = 12(approx)

2 men

1 men, 1day= 1/(5*8)= 1/120
1 women, 1 day= 1/(18*12)= 1/216
1 children, 1 day= 1/(16*20)= 1/320
12 women + 8 children, 1 day work= (12/216) + (8/320)]=29/360
So (12 women+8 children) 10 days work=290/360, Remaining work=7/36
If 'n' men are added to finish the work in 2 days, then 2*[(n/120)+(29/360)]=7/36, n=2
