There are six children playing football, namely A, B, C, D, E and F. A and E are brothers. F is the Sister of E. C is the only son of A's Uncle. B and D are the daughters of the brother of C's father. How is D related to A?
Answer: D) Cousin
Clearly, D's father is the brother of C's father and C's father is A's Uncle. So, D's father is also A's Uncle. Thus, D is A's cousin.
