.The hundreds digit of this number is 8 and the ones digits is 5.

\r\n" );
document.write( "So we know this much:\r\n" );
document.write( "\r\n" );
document.write( "8_5\r\n" );
document.write( "\r\n" );
document.write( "We just need to know the middle (tens) digit.\r\n" );
document.write( "

\n" ); document.write( "3-digit number is rounded to the nearest ten, the sum of its digits is 16
\n" ); document.write( "
\r\n" );
document.write( "When the number is rounded to the nearest ten, the number will have\r\n" );
document.write( "a 0 on the right end like this\r\n" );
document.write( "\r\n" );
document.write( "8_0\r\n" );
document.write( "\r\n" );
document.write( "In order to have a sum of 16, the missing digit in that rounded version\r\n" );
document.write( "will be 8, so we have:\r\n" );
document.write( "\r\n" );
document.write( "880 for the rounded version.\r\n" );
document.write( "\r\n" );
document.write( "Since the original number ended in 5, it had to cause the middle\r\n" );
document.write( "digit to round up.  So the tens digit must have been a 7.\r\n" );
document.write( "\r\n" );
document.write( "Therefore the original number had to be\r\n" );
document.write( "\r\n" );
document.write( "875.\r\n" );
document.write( "\r\n" );
document.write( "That way when rounded to the nearest ten, it would give 880,\r\n" );
document.write( "and the sum of those digits is 16.\r\n" );
document.write( "\r\n" );
document.write( "Answer: 875.\r\n" );
