Mrs. Rossi wrote the following clues for a Mystery number.\r
\n" ); document.write( "\n" ); document.write( "It is a four digit number
\n" ); document.write( "
\r\n" );
document.write( "So suppose it is ABCD\r\n" );
document.write( "

\n" ); document.write( "The tens are double the ones
\n" ); document.write( "The thousands are double the tens
\n" ); document.write( "
\r\n" );
document.write( "C is twice D and A is twice C.\r\n" );
document.write( "So A is 4 times D, so the number is\r\n" );
document.write( "either like this 4B21 or like this 8B42\r\n" );
document.write( "

\n" ); document.write( "the sum of the digits is 19
\n" ); document.write( "
\r\n" );
document.write( "The largest B can be is 9 and 4921 would\r\n" );
document.write( "only have a sum of digits 16.\r\n" );
document.write( "\r\n" );
document.write( "So the answer is 8B42 and B has to be 5 to\r\n" );
document.write( "make the sum of digits 19.\r\n" );
document.write( "

\n" ); document.write( "What number is it?
\n" ); document.write( "
\r\n" );
document.write( "8542\r\n" );
