    let us consider 5+7+4=36 47 30
    first two digits come from ([5+1]*4)+(5+7)=36
    then next 2 digits come from [5*(7+1)]+7=47
    the last 2 come from 5*(5+1)=30
    Similarly if we do for 7+3+5,we get
    first 2 digits are ([7+1]*5)+(7+3)=50
    next 2 are [7*(3+1)]+3=31
    last 2 are 7*(7+1)=56
    therefore answer is 503156....

    1st set: a*c + a+b+c = 5*4+5+7+4 = 36
    2nd set: a*b + a+b = 35+12 = 47
    3rd set: a*a+a = 9*9+9 = 90
    1. 5 + 7 + 4 = 364730.
    30 = (5*5)+5
    47 = (7*5) + 5+7
    36 = (4*5) + 5 + 7 + 4
    so 7 + 3 + 5 = 503156
