While solving the questions on blood relationship, one should be familiar with basic concepts like various relations.
Mother's or Father's Brother - Uncle Mother's or Father's Sister - Aunt Mother's or Father's Father - Grand Father Mother's or Father's Mother - Grand Mother Grand Father's or Grand Mother's Brother - Grand Uncle Grand Father's or Grand Mother's Sister - Grand Aunt Children's Children(Grand Son, Grand Daughter) - Grand Children Uncle or Aunt's Son/Daughter - Cousin Son's Wife - Daughter-in-law Daughter Husband - Son-in-law Sister's or Brother's Son - Nephew Sister's or Brother's Daughter - Niece Husband's or Wife's Brother or Sister's Husband - Brother-in-law Husband's or Wife's Sister or Brother Wife - Sister-in-law
Children of the same parent - Siblings Paternal relatives - Father side relations Maternal relatives - Mother side relations One's husband/wife - Spouse
The easiest and non-confusing way to solve blood relationship problems would be to draw a family tree diagram and increase the levels in the generation wise as shown below-
Generation 1 : Grand Parents-Grand father, Grandmother, Granduncle, Grand aunt.
Generation 2 : Parents & in laws-Father, Mother, Uncle, Aunt, Father-in-law, Mother-in-law
Generation 3 : Siblings, spouse & in laws-Brother, Sister, Cousin, Wife, Husband, Brother-in-law, Sister-in-law.
Generation 4 : Children & in laws-Son, Daughter, Niece, Nephew, Son-in-law, Daughter-in-law
Generation 5 : Grand children-Grand son, Grand daughter.
Below Examples illustrate the process for solving this kind of problems:

My husband means woman’s husband, wife of my husband means again women itself, daughter of the wife of my husband means woman’s daughter and brother of the daughter means woman’s son. So, the woman is the mother of the man in the photograph.
