Work done by 3 men = 5 women = 8 boys
1 man = 8/3 boys
6 men = 16 boys
1 woman = 8/5 boys
10 women = 16 boys
Now, 6 men + 10 women + 6 boys = 16 + 16 + 6 = 38 boys
8 boys need 38 days
1 boy needs (38x8) days
So, 38 boys need (38x8)/38 = 8days
1 man = 8/3 boys
6 men = 16 boys
1 woman = 8/5 boys
10 women = 16 boys
Now, 6 men + 10 women + 6 boys = 16 + 16 + 6 = 38 boys
8 boys need 38 days
1 boy needs (38x8) days
So, 38 boys need (38x8)/38 = 8days
