Sit in a RowTrick brain teasers appear difficult at first, but they have a trick that makes them really easy.
Georges, Patrick, Charlis, Samuel and Bruno are five Frenchmen. Georges knows English and Chinese. Patrick knows Chinese and Japanese. Charlis knows Japanese and German. Samuel knows German and English. Bruno knows them all: English, Chinese, Japanese and German.

HintLook at its category.
They are Frenchmen, and can all speak French. Therefore, any order is OK.
