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?
Explanation:
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?
Explanation:

of the daughters of Vasudha’s father means Vasudha’s sister.
