dragons den live

Did anyone watch the Dragons Den last night BBC2 UK?
There was a woman on there selling furniture. Does anyone know how she got away with earning £11k profit in a year on her business and still claimed state benefits? Are you allowed to do that?
Please dont think I am knocking her in anyway as I admire her for doing this its just I know people who would love to have a go at their own business but have been hindered by the fact of having nothing to live on. All answers appreciated.
If you earn under a certain amount your still entitled to some income support I think, I should think 11k is about borderline.
I wanted one of those ladder toolboxes lol
