The number either begins with $\"7\"$ or $\"8\"$
\n" ); document.write( "If the tens digit is $\"7\"$ , the units digit is $\"4\"$ or less
\n" ); document.write( "If the tens digit is $\"8\"$ , the units digit is $\"3\"$ or less
\n" ); document.write( "and
\n" ); document.write( "If the product of the digits, the tens digit can't be $\"8\"$ ,
\n" ); document.write( "since $\"8%2A3+=+24\"$ is the most the product can be
\n" ); document.write( "and
\n" ); document.write( "George's number must be $\"74\"$ , since $\"7%2A4+=+28\"$
\n" ); document.write( "which is OK, and $\"7%2A3+=+21\"$ which fails the 2nd test \n" ); document.write( "

\n" );
