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

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