Blood Relations Reasoning

The arrangement for determining the relationship based on the descendants of their forefathers between two or more people is called blood relations. In this type of question, there are links to any two or more people. On the basis of these relations, the relationship with another person has to be determined.

To solve these types of questions, it is necessary to know about the relationships that identify the relation on your own basis. Questions related to blood links should be resolved by removing the relationship in a phased manner. In order to solve such questions, the signs and diagrams should be used so that the relation can be made accessible.



In relation to blood related questions, take the related statement to the person whose relationship has been asked first, and reach the person using the least statements, which is related to the relationship. It is necessary to find out the gender of a person whose relationship is asked (male or female).
