TYPE 1: Deciphering Jumbled Up Descriptions

In this type of questions, a round-about description is given in the form of certain small relationships and direct relationship between the persons concerned is to be deciphered.

Example:    Anil introduces Rohit as the son of the only brother of his father’s wife. How is Rohit related to Anil?






Answer:       The relations may be analyzed as follows:

Father’s wife----Mother;

Mother’s brother----Uncle;

Uncle’s son ---Cousin

So, Rohit is Anil’s cousin. Hence, the answer is (a).

Tip:                 an easy way for solving such question is to consider yourself as one of the related person in given description. For instance considering yourself as ‘anil’ in the above question will make it lot easier to decipher the question.

TYPE 2: Relation Puzzle

In this type of question the information related to a particular relationship or a relative is given in an indirect way. The information given is related to one or more than one person and you have to find the other person in a relation.

Example:  Given that:

      1. A is the mother of B;
      2. C is the son of A;
      3. D is the brother of E;
      4. E is the daughter of B.

The grandmother of D is

  1. A                  
  2. B               
  3. C            
  4. D               
  5. E

Answer:       D is the brother of E and E is the daughter of B. This means that D is the son of B.

                    Also, A is the mother of B.

                    So, A is the grandmother of D.

                    Hence, the answer is (a).


Tip:                 another way of solving these types of questions is to draw a diagram to represent the question. It will make it more convenient to decipher the given relationship. Refer to the following figure.( (+) is used to represent male while (-) is for females)
