If in coded language
2+6+7=24
8+2+8=73
3+4+4=40
Then
7+3+9=??

• Consider LHS
  As we hav
  (2+6+7)+9=24
  (3+4+4)+29=40
  (8+2+8)+55=73
  (7+3+9)+87=106
  Now Consider no.
  9 then 29 then 55 then 87
  Its series of difference 29 and 9 as 5×4+0=20
  Then 55 and 29 as 5×5+1=26
  Then 87 and 55 as 5×6+2=32

• answer can be 67 or 76 or 58 or 85 or 49 or 94, because, adding the digits of all these numbers gives 13 as result.
  solution is:-
  2+6+7=15 and 2+4=6 =>15-6=9
  8+2+8=18 and 7+3=10 =>18-10=8
  3+4+4=11 and 4+0=4 =>11-4=7
  7+3+9=19 and 6+7=13 =>19-13=6

• 2*6*7-(2*(7-2)*6))+((7-6-1)*(7-2-1)(7-6+7-7)
  =84-60-0=24
  ------------
  3*4*4-(2*(4-3)*4)+(4-4-1)*(4-3-1)(4-4+4-5)
  =48-8=40
  -------------
  8*2*8-(2*(8-8)*2)+(8-8-1)*(8-2-1)(8-2-1+8-2)
  128+0-55=73
  --------------
  7*3*9-(2*(9-7)*3)+(9-3-1)*(9-7-1)(9-3+9-4)
  =232
  a+b+c =232
  a*b*c-(2*(c-a)*b)+(c-a-1)*(c-b-1)*(2c-2b-1)
