Question 1133718
<br>
Take any 3-digit number, reverse the digits, and find the difference between the two numbers.  The difference will always be 99n, where n is the difference between the first and last digits.<br>
In this problem, the middle digit is the sum of the other two digits, and the sum of all three digits is 14.  That means the middle digit is 7.<br>
Since the difference between the two 3-digit numbers is 99, the difference between the first and last digits is 1.  Then, since the sum of the first and last digits is 7, those digits are 3 and 4.  So the two 3-digit numbers are 374 and 473.<br>
The problem says that the original number is smaller, so...<br>
ANSWER: the original number is 374
