I love hedge fund brainteaser questions. NOT! But they are used. We can spend a lot of time talking about whether they are valid or not, but they are used. You have to be prepared for them.

Today's question is 1 of those fun ones. It's a math problem.. "And all the numbers between 1 and 100. What do you get?"

You can't just sit there and have a mental column in your head and start going, "one, 3,6, 10 …" There is just no time for that. They're not going to just sit there while you go through this routine. So, what's the answer? How do you figure this out?

If you think about it every individual member has an opposite reciprocal number that adds up to 100. For example, 99 and 1. 98 and 2. 97 and 3. On and on and on.

When you realize that there are 50 pairs that had to up to 100, you have 5000 (remember, you have 100 and 0). But, there is one number that doesn't have a parent – – 50.

So the answer becomes 5050.

So, again, there's always a trip to the question that you are asked, especially with the math ones. So this is the trick for any all the numbers from 1 to 100.
