Blood Relations

Category : 6th Class

In this section, problems are based on blood relations. The process of solving these problems (puzzles) depends upon the deeply knowledge of blood relations. The common relations are: Father, Mother, Grandparents, Wife, Husband, Son, Daughter, Grandchild, Sister, Brother etc.



1. Relatives on the mother's side are called 'maternal'. For example, mother's brother is called maternal uncle.

2. Relatives on the father's side are called 'paternal'. For example, father's brother is called paternal uncle.

3. Assume a relation as paternal relation, unless stated otherwise.



  • To solve problems, find right gender of required relation and eliminate all wrong choices if any. Also find generation gaps to solve quickly..
  • You can solve by drawing a generation diagram. For this put lower generation below the upper generation and mention M (or m) and F (or f) within brackets for male and female respectively.
  • Note: Someone's gender can not be decided by his/her name.





Pointing to a lady in the photograph, Neeloo said, "Her son's father is the son-in-law of my mother." How is Neeloo related to the lady?

(a) Aunt                         (b) Sister                        (c) Mother                             (d) Cousin


Explanation (b):

Lady's son's father is lady's husband.

So, the lady's husband is the son-in-law of Neeloo's mother, i.e. the lady is the daughter of Neeloo's mother.

Thus, Neeloo is the lady's sister.

Hence, the correct option is (b).
