A mother and her friend are talking about how many chidren they have. The friend knows how many daughters the mother has, but doesn't know how many sons she has. The mother says:

"All of my children have the same amount of brothers and the same amount of sisters as the other children."

Now the friend knew how many sons she had. How many sons did the mother have?

Hi
I just visited this site in search for sum good logic prob and read this one.
I think the mother can have 1)all daughters and no son
or 2)all sons and no daughter.
So that in the first case if X is the no. of daughters then each one of them would hv (X-1) sisters ans zero brothers.In the second case each one of them would hv (X-1) brothers.
