Let the men be m, women be w and the children be c
According to the given condition, two equations can be formed
3m + 2w + 0.5c = 20...........(i)
m+w+c = 20..........(ii)
m = 20-(w+c).........(iii)
From equation i and iii
3(20-(w+c)) + 2w + 0.5 c = 20
60 - 3w-3c+2w+0.5c = 20
40 = w+5c/2
=> c = 2(40-w)/5
For c is to be integer,
w = 5, w= 10, w = 15 and so on

w= 5, c = 14, m = 1
w=10, c=12, m = (-)ve
Thus, and is ,
w= 5, c =14 and m =1
