  Men = 1
  
  Women = 5
  
  Children = 14
  
  Total = 1*3 + 5 *2 + 14*.5 = 20..

  Ya, that's right.
  But is that the only answer?
  
  Two equations with three unknowns, so there are many answers possible, right?

  X+Y+Z=20
  3X+2Y+0.5Z=20
  These are the two equations. X,Y,Z are the number of breads.
  In simple maths, there can be many answers possible. But here, we are dealing with number of persons. So we cannot take decimal answers. This is the only integer answer possible i think.

  here we got 2 equations,
  x+y+z=20, and 3x+2y+0.5z=20
  then after solving last equation we get 6x+4y+z=40,
  from this one i do following: x+y+z+5x+3y=40, as x+y+z=20 then 20 +5x+3y=40, then 5x+3y=20,
  as you see here x can be only 1, x=1 , because another answers are not valid with 3y,
  so x=1 then y to be 5,y=5, 5*1+3*y=20, x=1,y=5 is only solution for this equation, so z=14, from x+y+z=20

  This can also be the answer.
  Men=4
  Women=3
  Children=2
  Check=(4*3)+(3*2)+(4*0.5)=20
  N there may be many more answers....if not so then why?
