5+7+4=364730
9+6+3=456990
8+2+9=912672
then
7+3+5=??????

• I don't think the previous solution is acceptable since the the digits should be used only one. It is like this: If we have
  A+B+C = =A*(A + 100*B + 10000*C + 10101)+100*(101*B + 100*C)
  If {A,B,C} = {5,7,4}, then 5+7+4 = 364730
  If {A,B,C} = {9,6,3}, then 9+6+3 = 456990
  If {A,B,C} = {8,2,9}, then 8+2+9 = 912672
  If {A,B,C} = {7,3,5}, then 7+3+5 = 503156
  This is just a bad problem. BTW I did not know IAS has such kind of puzzles. Are you sure it was asked in IAS?

• for 5+7+4=36 47 30
  
  first two digits of first answer comes by {(5+1)*4}+(5+7)=36
  
  for 2nd two digits of first answer by {5*(7+1)}+7=47
  
  for last two digits by 5*(5+1)=30 similarly 7+3+5=503156
  ans is 503156

• e.g
  574 364730
  L.H.S take the first integer and add 1 which is now 6
  R.H.S
  6*(first digit) 30
  6*(second digit) + first digit 47
  6*third digit + first and second digit 36
  
  same case applies for second, third and fourth, so answer is 503156.

• According to question,
  
  30 = 5 * ( 5 + 1)
  47 = ( 7 * 6 ) + 5
  36 = ( 4 * 6 ) + ( 5 + 7)
  
  90 = 9 * ( 9 + 1)
  69 = ( 6 * 10 ) + 9
  45 = ( 3 * 10 ) + 9 + 6
  
  72 = 8 * ( 8 + 1 )
  26 = ( 2 * 9 ) + 8
  91 = ( 9 * 9 ) + 8 + 2
  On calculation,
  
  7 + 3 + 5
  => 7 * ( 7 + 1 ) = 56
  => ( 3 * 8) + 7 = 31
  => ( 5 * 8 ) + 7 + 3 = 50
  
  therefore, the answer is 503156.

• Answer is 503156.
  50 = 7*5+(7+3+5)
  31 = 7*3+(7+3)
  56 = 7*7 + 7

• Example: 5+7+4=364730
  consider A+B+C=??????
  So, A=5,B=7,C=4
  1st two digit 36= (A+B+C)+(A*C)
  2nd two digit 47=(A+B)+(A*C)
  3rd two digit 30=(A)*(A+1)
  like wise
  7+3+5=503156

• (5*4)+(5+7+4)=36,(5*7)+(5+7)=47,(5*5+5)=30...we will get 364730
  Like wise for 7+3+5 we will get as (7*5+(7+3+5))=50,(7*3)+(7+3)=31,(7*7+7)=56....so the answer is 503156

• Use these rules: 
  1st two digits = (A + B + C) + (A * C) 
  2nd two digits = (A + B) + (A * B) 
  3rd two digits =A*(A + 1)
