If three numbers are added in pairs, the sums equal 10, 19 and 21. Find the numbers

• 15,6,4.
  
  If nos are x,y,z, then
  2*(x+y+z) = 10+19+21 =50
  x+y+z=25.
  
  then nos are (25-10), (25-19), (25-21) or 15,6,4.

• Let the numbers be x, y and z. Then,
  
  x+ y = 10 ...(i) y + z = 19 ...(ii) x + z = 21 …(iii)
  
  Adding (i),(ii)and(iii),we get: 2 (x + y + z ) = 50 or (x + y + z) = 25.
  
  Thus, x= (25 - 19) = 6; y = (25 - 21) = 4; z = (25 - 10) = 15.
  
  Hence, the required numbers are 6, 4 and 15.
