GIVE 1-9 NUMBERS TO THESE LETTERS SUCH THAT SUM IN ANY ROW OR COLUMN SHOULD BE EQUAL TO "13" AND NO NUMBER SHOULD BE REPEATED

• Its not possible in the way the pattern is mentioned. Because the column ADEHI is too long. Even if you keep 9,8 away in ABC and EFG, still 7+5+6 many digits left. However, this can be done in this pattern :
  
  A + B + C
  ............D
  ............E + F + G
  ........................H
  ........................I
  
  in this case the solution will be :
  
  9 + 3 + 1
  ............8
  ............4 + 7 + 2
  ........................5
  ........................6
