Question 546759
I have 2 digits. 

I am more than 70 but less than 80. 
<pre>
All the natural numbers that are more than 70 but less than 80 
have 7 as their tens digit.
</pre>
The digits have a sum of 12.
<pre>
The only ones digit that would add to that 7 to give 12 is a 5. So the
answer is 75. 
</pre>
The number in my ones place is a 5. both of my digits are odd. 
<pre>
We didn't need either of those two pieces of information to know the
answer is 75.
