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.

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.
