Blood Relations

Blood relation is one of the most tricky parts of competitive exams. It questions the logical thinking of one. It tests how quickly someone approaches logic with the help of a diagram or chart instead of mathematical calculations. Let’s understand the blood relations to crack these questions.

What is a blood relation?

The blood relation is a relation in the world that is either by birth or marriage. For example, a relation by birth is father, mother, uncle, and son. While relations by marriage are father-in-law, mother-in-law, brother-in-law, etc.  

Types of questions based on blood relation

Over the passage of time, the blood relation question has changed various types. Earlier the questions which were asked were less complex. They were just statement or dialogue-based questions. Blood relation questions now have become very complex and tiring with the rising competition in competitive exams.

  • Coding-Decoding: It is one of the recent types of blood relation questions. In these questions, relations are represented by symbols. 
  • Based on Puzzles: The complexity of blood relation questions is increased by asking them in a puzzle form. Here, brief information about the relation between people is provided and sub-question are asked on the basis of that.

  • These questions appear to be lengthy. But don’t worry they are easy to solve if not attempted in panic.

Blood Relation Chart

The blood relations grow like a tree, it has roots, and then spread onto branches and sub-branches just like our ancestors act like roots, and then their children become branches and grandchildren sub-branches. 

Things you should keep in mind while constructing a blood Relation Chart

  • Husband and wife should be placed together.

  1. A%B means A is the brother of B.
  2. A$B means A is the sister of B.
  3. A#b means A is the father of B.

The Shukla family went to the photographer for their family photograph to add in their family photo album. The photographer arranged them in a straight row facing the South. The family members were Anshu, Rama, Krishna, Deeva, and Sonu.

  1. Anshu was sitting third to the right of his daughter.
  2. Rama was sitting on the right of Krishna, whose husband is the brother of Rama.
  3. Anshu and Sonu were sitting next to each other.
  4. Deeva was not an immediate neighbor of Anshu’s son.
  5. Deeva was sitting at the left end and the mother of Deeva is Krishna, who was the wife of Anshu.
