Excel 2007 : Advanced Filtering criteria

Hi, I'm doing my homework in Excel about Advanced Filtering and I can't create a formula that filters me some stuff.

So here's the thing: let's say we have a table like this:

Name:------Age:----Brothers:----Sisters:
Tom--------19------2------------5
Jane--------24------3------------1
Anthony----32------3-------------0
Tim---------42------3------------2

And I need a formula to filter out all who has age between 25-30 and who's older than 40. In our example the result would be Tom, Jane and Tim, but what would be the formula? I've googled hours for this, but I just can't find anything. If I think I got it, it won't work.

Ok, here's another one. I need a formula to filter out everyone who has 3 brothers and who has atleast 1 sisters. In our example the result would be Jane and Tim.

Please help me on this one, realy stuck at it.
Thanks.
