    Answer :   366329

    PROCESS-

    a+b+c
    First 2 digits    =   a*b
    Next 2 digits    =   c*a
    Last 2 digits     =   Reverse of (((a*b)+(a*c))-c)


    Solution-

    3+5+6
    First 2 digits    =   a*b                                                        =    15
    Next 2 digits    =   c*a                                                         =    18
    Last 2 digits     =   Reverse of (((a*b)+(a*c))-c)     =    Reverse(15+18-6) = Reverse(27)  = 72
    Final value 151872

    Similarly,
    For Given Question –

    9+4+7

    First 2 digit = 36
    Next 2 Digit = 63
    Last Digits   = 29

    So, Solution – 366329

    Nice.  The first four digits were easy.  An alternative for the last two digits is:

    11a – 16b + 7c + 77

    but that gives 161 for 9+4+7.  While this answer is consistent, it’s inelegant and unsatisfactory:

    x = 10000ab + 100ac + 11a -16b + 7c + 77

    It yields 9 + 4 + 7 = 366461

    So while 366461 is *an* answer, it is not the best answer.
