2 men and 3 boy can do a piece of work in 3 days .
3 men and 2 boy can do a piece of work in 8 days
3 men and 2 boys can do a piece of work in 1 day = 1/3 + 1/2
= 5/6
1 men and 2 boy can do a piece of work in 1 day = 1/3+5/6
= 7/6
1 men and 1 boy can do a piece of work in 1 day = 1/2+7/6
= 10/6
2 men and 1 boy can do a piece of work in 1 day = 10/6×2
=10/3
