document.write( "\r\n" );
document.write( "A)81 becomes 18 when turned upside-down, and decreases by 63, not by 12\r\n" );
document.write( "\r\n" );
document.write( "B)69 stays 69, and neither decreases nor increases, so it doesn't decrease by 12\r\n" );
document.write( "\r\n" );
document.write( "C)16  becomes 91 when turned upside-down, and increases by 75, it doesn't decrease by 12\r\n" );
document.write( "\r\n" );
document.write( "D)98 becomes 86 when turned upside-down, and decreases by 12.  So D) is the answer.\r\n" );
