Question 1135440
<br>
You read something into the problem that wasn't there -- you only counted the 3-digit numbers....<br>
There are also 1- and 2-digit numbers that satisfy the requirements.<br>
You will find the correct answer is indeed 25.<br>
---------------------------------------------------------------<br>
The question asks for the number of odd numbers you can make that are less than 700, using the given digits.  You found and counted only the 3-digit numbers that satisfy the requirements; the problem didn't specify 3-digit numbers.<br>
5 is an example of a 1-digit number that is odd and less than 700; 67 is an example of a 2-digit number that is less than 700.<br>
And there are more... making 25 the total number of odd numbers that are less than 700 and use only the given digits.
