Question

someone's mom has four sons, north,east and west. What is the name of fourth son?

Answer 1

Thank you for asking this question. This question is tricky but a very easy one
A person would first think that the answer might be south as north east and west are already told. 
But in the question it states the the child is someone as its already stated that someone's mom has four children. So the fourth son is someone.
I hope this answer can help you in some manner.

Answer 2

Bonjour!

According to the question,It is given that someone's mom has four sons and the name of son is north, east and west.
So, the name of 4th son is "Someone" bcz it is given(that it's someone's mom).

Hope this helps...:)
