Blood Relations Question & Answer

Blood Relations topic is a subset of the larger Verbal Reasoning section of the syllabus. Blood relations questions are fairly straightforward as the name itself suggests. A number of persons or characters are provided in the question and candidates are asked to determine how one particular character is related to another. Questions based on Blood Relations are evaluated in examinations such as SBI PO, SBI Clerk, MAT, NPS Trust Officer Grade A, NPS Trust Officer Grade B, NHB, PFRDA Grade A, NABARD Grade A and NABARD Grade B among others. Blood Relations questions are asked as jumbled up relations or identifying familial relations.

  • Daughter
  • Mother
  • Aunt

Coding-Decoding or Coded Blood Relations

Another format in which Blood Relations questions can be tested is via Coding and Decoding. Here, the persons and their relation to each other is presented in terms of codes utilizing alphabets, numbers and arithmetic operations. While the question and the assessment remain the same, the presentation of the question is made difficult. This is done purposely to complicate questions. However, candidates need not to get worked up when they come across such questions.

To solve such questions, we first have to decode the question given and then write in a simpler form. Let us understand it with the following example.

Let us study with an example.

Read the following information carefully and answer the given questions:

  • P + Q means P is the sister of Q
  • P # Q means P is the husband of Q
  • P $ Q means P is the daughter of Q
  • P % Q means P is the mother of Q
  • P @ Q means P is the brother of Q

What should come in place of the question mark, to establish that Q is the child of B in the expression?

T % B # U % M + O ? Q

  • 1) Only %
  • 2) Either + or @
  • 3) Only #
  • 4) Either @
  • 5) Only +

Ans: 2
