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?

(In reply to Solution by DJ)

the mother could have had zero sons or zero daughters
this is because knowing a number of sumthing does not force that number to be a nonzero integer.
for instance: i know that i have no cans of soda in the refridgerator......i kno the number of cans, and that number happens to be 0
