POINTS TO REMEMBER : 

• If the question is "How is A related to B". Then you must know the gender of A to answer the question
• Without knowing A's gender, you cannot determine the relation from A to B
• If a person is Uncle or Aunt to "A", A is that person's nephew (if A is Male) or niece (if A is female)
• Cousin is a common Gender (I mean, you can use this word for both Male and Female)
• Ex : A says to B, "you are the son of my grand father's only son".
• How is B related to A?
• How is A related to B?
• Ans : 
• B is Brother of A.
• My grand father's only son = A's father (grand father's only son means only ONE son.. No other son and no daughter also)
• A is either brother or sister to B
• A and B are siblings. B is brother to A as we know the Gender of B. But we dont know the Gender of A. So we cant say whether A is Brother or Sister to B.
