\n" ); document.write( "(1) It is a 3 digit whole number
\n" ); document.write( "(2) It is divisible by 5
\n" ); document.write( "(3) It is a positive even number
\n" ); document.write( "(4) Each of its digits are different
\n" ); document.write( "(5) Its tens digit is greater than its ones digit
\n" ); document.write( "(6) Its hundreds digit is greater than its tens digit
\n" ); document.write( "(7) It is less than 400
\n" ); document.write( "(8) It is divisible by 3
\n" ); document.write( "(9) It has only one odd digit
\n" ); document.write( "(1)0 Its ten digit is 1
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "From (2), the last digit is 5 or 0.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then from (3), we conclude that the last digit is 0. \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From (10), the last two digits are 10.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From (6) and (7), first digit is 2 or 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From (8),  we conclude that first digit is 2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The number is 210.    ANSWER\r\n" );
document.write( "
\r
\n" ); document.write( "\n" ); document.write( "Solved.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "All other conditions, (4), (5), (9) are excessive: they are not used in the solution.\r
