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.

In how many ways can they sit in a row, such that any two neighboring persons have no problems in communication?

Nice questions Prateek.

They can sit in 48 ways so that any two neighbors can communicate with each other.

It is not mentioned that they all know french. Even if they are frenchmen, they may be staying in different countries and not know french at all :)

This is a logic question, you cant suppose :)

Rashid bhai...

"they all know french" is also an assumption :) isn't it?

Now Prateek Bhai will clarify wink

They can sit in 5! ways.......

Answer Plzz.....i guess it shud b 120blush

5*4*3*2*1 ways

The correct answer is actually 120 ways...

Since they are all Frenchmen, hence any way they sit...they would not be facing any communication problems.

Hi Prateek,

I have a different opinion here.

Even if they are frenchmen, it is not necessary that they all know French.

I agree that unlike India, they would have multiple languages but still with the given information, I think it is inappropriate to assume that they all know French.

Aseem, Priya, Sushil - what do you think?
