A+B+C+D=D+E+F+G=G+H+I=17 where each letter represent a number from 1 to 9. Find out what does letter D and G represent if letter A= 4.

• Its tricky but simple
  A+B+C+D+E+F+G+H+I = (1+2+3+4+5+6+7+8+9) = 45
  17 + (17 - D) + (17 - G) = 45
  D+G = 51-45 = 6
  so D+G = 6,There are only two choices (4,2) or (5,1)
  but 4 is already assigned to A,so take second pair (5,1).
  There are again two possibilities
  (D,G) = (5,1) and
  (D,G) = (1,5).
  by trial and error ( by checking the given data)
  we get D=5,G=1

• Add the 3 equations.
  we get D+G+(A+B+C...I)=51 =>D+G + 45=51 => D+G=6.
  so D,G can be among 2,4(nt pssble as A=4) or 1,5 or 3,3(Duplicate nt pssble).
  so 1,5 only pssble.
  now in eqn 2( d+e+f+g=17)
  e+f=11
  now in eqn 3
  If we take G=5, H+I=12.not pssble as E+F=11(6,5 or 7,4 or 8,3 or 9,2)
  if G=1, H+I=16(possible H,I=9,8)

• D=2,G=7,
  A+B+C+D=D+E+F+G=G+H+I=17
  i4+5+6+2=2+8+1+7=7+7+3=17
