Cousin : Mother's or Father's Brother's or Sister's Son or Daughter (or) Parent's siblings' son or daughter (or) Uncle's or Aunt's son or daughter.

Nephew : Brother's or Sister's son

Niece : Brother's or Sister's daughter.

Uncle : Father's or Mother's brother.


 Aunt : Father's or Mother's sister


Father-in-Law : Spouse's father (or) Wife's or Husband's Father

Mother-in-Law : Spouse's mother (or) Wife's or Husband's Mother

Son-in-Law : Daughter's Husband

Daughter-in-Law : Son's wife


Brother-in-Law : Spouse's brother (or) Sister's husband


Sister-in-Law : Spouse's sister (or) Brother's Wife


Maternal : of or related to Mother

Paternal : of or related to Father

Siblings : brothers or sisters

Spouse : Husband or Wife

Note : Cousin is a COMMON GENDER, There are NO such words Cousin Brother / Cousin Sister

Generations : 
-2 Generation : Grand father and Grand Mother (Maternal & Paternal)
-1 Generation : Mother, Father, Brother, Sister, Brother-in-Law, Sister-in-Law, Cousin
+1 Generation : Son, Daughter, Son-in-Law, Daughter-in-Law, Nephew, Niece
+2 Generation : Grand Sons and Grand Daughters

POINTS TO REMEMBER : 

  • If the question is "How is A related to B". Then you must know the gender of A to answer the question
    • Without knowing A's gender, you cannot determine the relation from A to B
  • If a person is Uncle or Aunt to "A", A is that person's nephew (if A is Male) or niece (if A is female)
  • Cousin is a common Gender (I mean, you can use this word for both Male and Female)
    • Ex : A says to B, "you are the son of my grand father's only son".
      • How is B related to A?
      • How is A related to B?
    • Ans : 
      • B is Brother of A.
        • My grand father's only son = A's father (grand father's only son means only ONE son.. No other son and no daughter also)
      • A is either brother or sister to B
        • A and B are siblings. B is brother to A as we know the Gender of B. But we dont know the Gender of A. So we cant say whether A is Brother or Sister to B.
Lets have a look at some practice problems :

  • The mother of Ranbir is the only daughter of  Neetu's  father. How  Neetu is related to Ranbir?
    • Sister
    • Mother
    • Aunt
    • Cant determine
    • None of These
           Answer : Mother
          Explnation : Only daughter of Neetu's father  = Neetu only.
           The mother of Ranbir is Neetu, so Neetu is the mother of Ranbir :D
  • Amit is the son of Ajit's grand father's only daughter. How is Ajit's father related to Amit?
    • Grand Father
    • Uncle
    • Father
    • Data Inadequate
    • None of these
             Answer : Father
             Explanation : Ajit's grand father's only daughter means Ajit's mother. Amit is the son of Ajit's mother. 
                           So, Amit and Ajit are Siblings. Ajit's father is Amith's father too

  • Pointing to a boy Rekha said, "He is the son of my mother-in-law's only Child". How is the boy related to Rekha?
    • Son
    • Grand Son
    • Nephew
    • Brother
    • Cant determined
                Ans : Son
                Explnation : My mother-in-law's only child = Rekha's mother-in-law's only child = Rekha's husband.
                                    The boy is the son of the Rekha's Husband. So obviuosly Rekha is the mother to that
                                    boy and that boy is the Son of Rekha.
  • B is the husband of C. A is the sister of B. D is the sister of C. How is D related to B?
  • Son
    • Uncle
    • Sister-in-Law
    • Cant be determined
                Ans : Sister-in-Law
                Explnation : 
      •  B is Husband and C is his Wife. 
      • A is the sister of B, so A is the Sister-in-Law of C ( Husband's sister)
      • D is the sister of C so, D is the Sister-in-Law of B (Wife's Sister)
  • Pointing towards a girl, a Person said, "She is the only daugher of the only son of the wife of the father-in-law of my wife". How is the girl related to the Person?
    • Niece
    • Daughter
    • Sister
    • Daughter-in-Law
    • Cant be Determined
               Ans : Daughter
               Explnation : 
      • Father-in-Law of my wife = Father in Law of the Person's Wife = Person's Father
      • Wife of the Father-in-law of my wife = Wife of the Person's Father = Person's Mother.
      •  Only son of Person's Mother = That Person only (because Person's parents dont have any other child)
      • So, she is the only daughter of Person as the Person does not have any other Children.

    1. Re read the question lovely. A says to B "YOU ARE THE SON OF my grand father's only son"

      your logic is correct till the grand father's only son... means father...

      but A is saying to B that "you are the son of my father". Whats that mean? :)

      Brother

    1. Check the sentence again Friend. Its Mother's or Father's Brother's or Sister's Son or Daughter.

      in simple sense Mother / Father's Brother's/Sister's Son/Daughter.
