A + B + C +D = D + E + F + G = G + H + I =17. If A = 4. What are the values of D and G. Each letter taken only one of the digit from 1 to 9.

• hi guys plz tell me frm whr should i prepare for cryptography??? plz tell me the online site..thanx in advance..:)

• Each alphabet represent unique digit from 1-9
  A B C D E F G H I
  1 2 3 4 5 6 7 8 9
  equation for this...
  1+2+3+.....+9=9(9+1)/2=45---------eq(1)
  
  
  A+B+C+D=D+E+F+G=G+H+I=17
  hence...
  A+B+C+D+D+E+F+G+G+H+I=17+17+17
  
  45+D+G=51
  45-51=D+G
  6=D+G given that D=4
  G=2

• A+B+C+D=D+E+F+G=G+H+I=17
  =>
  A+B+C+D+D+E+F+G+G+H+I=17+17+17=51
  => D+G=6
  =>D=1 and G=5
  or D=2 and G=4 and vise versa.
  (But, Since A is already 4. So last is not possible ).
  Thus possible values are D=1 and G=5 or vise versa => G=1 and D=5.

• Well we consider the given conditions first.
  A=4
  'A' to 'I' takes values from 1 to 9
  Step (i): sum all of them
  (A + B + C +D) + (D + E + F + G )+ (G + H + I) =17+17+17
  Step (ii): Sum of 1+2+3+.....+9= 45
  i,e; A + B + C + D + E + F + G + H + I = 45
  Step (iii): Separating excess D & G present in Step(i), we get
  45+(D+g) = 51
  => D+G = 6
  where as possible combinations are: (1+5), (2+4), (3+3). Since A=4 and numbers don't get repeated, we are left with 1&5.
