Important points to remember : 1) If the question is “how is A related to B”, we must know the gender of A to answer this question. Without knowing A’s gender, we can not determine the relation from A to B. 2) If a person is uncle or aunt to ‘A’, A is that person’s nephew ( if A is a male) or niece (if A is a female) 3) Cousin is a common gender. Example : A says to B, “ you are the son of my grand father’s only son”. Q 1) How is B related to A? Q 2) How is A related to B? Explanation : A 1) B is brother to 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 2) 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 do not know the gender of A. Some of the previous questions 1) The mother of Sukesh is the only daughter of Saritha’s father.
