Hmm..........for this you need to have 2 sets of 5 resistors which are connected in parallel to each other. The two sets are then connected in series. I'll try to draw it for you.

Sorry but am not very good in paint. :P

Anyway all the resistors are equal 100 Ohms. In the first set, 5 resistors connected in parallel gives a resultant resistance of 20 Ohm. So two of these sets connected in series gives 40 Ohms.  :D

I can't think of any other way for the time being. Will update if I find another way. ;)
