\n" ); document.write( "\n" ); document.write( "Let the number be ABBBC\r
\n" ); document.write( "\n" ); document.write( "A can be any one of 4,5, or 6\r
\n" ); document.write( "\n" ); document.write( "C can only be 5, 6, 7, 8, or 9, subject to C > A\r
\n" ); document.write( "\n" ); document.write( "Finally, A+3B+C = 19\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We want 19-A-C to be divisible by 3, subject to C > A, there are three possible cases to consider:
\n" ); document.write( "19-10 = 9
\n" ); document.write( "19-13 = 6
\n" ); document.write( "19-16 = 3\r
\n" ); document.write( "\n" ); document.write( "So we need to check cases where A+C = 10, A+C = 13, and A+C = 16 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A+C = 10:
\n" ); document.write( "=========
\n" ); document.write( "A=4, C=6: 19-4-6 = 9 ---> B = 9/3 = 3, so 43336 is one solution\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A+C = 13:
\n" ); document.write( "=========
\n" ); document.write( "A=4, C=9: 19-4-9 = 6 ---> B = 2, so 42229 is another solution
\n" ); document.write( "A=5, C=8: 19-5-8 = 6 ---> B = 2, so 52228 is a solution
\n" ); document.write( "A=6, C=7: 19-6-7 = 6 ---> B = 2, so 62227 is a solution\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A+C = 16:
\n" ); document.write( "=========
\n" ); document.write( "There are no cases for A+C = 16, for even if we choose the maximum value of A, which is A=6, we find C=10 and that is not a single digit.
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "I think these are all of the solutions: 43336, 42229, 52228, and 62227\r
