P's father Q is B's paternal uncle and A's husband M is P's paternal uncle. How is A related to B ?
A. Cousin
B. Aunt
C. Mother
D. Data inadequate
E. None of these
Answer: Option C
Solution (By Examveda Team)
Q is the paternal uncle of B, means Q is the brother of P's father. P is the son of Q. So, B's father and P's father are brothers.Also, M is the paternal uncle of P, means M is the brother of P's father. So, M is the father of B. Since A is the wife of M, so A is the mother of B.

According to me
Option B is also correct and option D is not bad.
It is not mention anywhere that M is only brother of Q so how can you be so sure that A is mother of B. There is one other possibility which says that A can be Aunt of B so Data is not adequate to answer this question
It has clearly not been stated in the question that M is the only brother of Q and even the answer option consists of both mother and Aunt as answers.
how come C is the correct answer? where is it written that M is the only brother of Q?
