Question 1209243
<br>
There are more conditions than necessary to find the number; but which ones are not needed depends on how you solve the problem.  And since there are more conditions than needed, there are many ways to solve the problem.<br>
Glancing quickly at the given conditions, this is the path I first saw:<br>
Its tens digit is 1; its tens digit is greater than its ones digit.<br>
Therefore, since it is a 3-digit number, it is _10.<br>
Then, since it is less than 400 and is divisible by 3, it must be 210.<br>
ANSWER: 210<br>
