How to solve blood relations problems:
For solving questions on blood relations, the best method is to backtrack, i.e., start with the last information in the question and proceed backward
For example, pointing to a lady  Gupta said “ She is the daughter of my grandmother’s only son.”
Then first, go with the last information, “my grandmother’s only son.“ My grandmothers' only son means my father. Now the daughter of my grandmothers' only son” becomes the daughter of my father. Daughter of my father is my sister.
Hence “she is the daughter of my grandmothers' only son “ becomes my sister.
Hence the lady is the sister of Gupta or Gupta is the brother of that lady.

Example 1: Sharma said, “ This woman is the wife of the grandson of my mother.” How is Sharma related to that woman?
Grandson of Sharma’s mother means Sharma’s son.
Wife of the grandson of Sharma‘s mother means Sharma’s daughter-in-law.
Hence, Sharma is the father-in-law of that woman
Example 2: Pointing to a person, Sudheer said to Vasudha” His mother is one of the daughters of your father “. How was Vasudha related to the person?
One of the daughters of Vasudha’s father means Vasudha’s sister.
Then the person’s mother is the Vasudha’s sister.

Hence Vasudha is person’s Aunt.
