Blood relation questions are a very important topic from the Logical Reasoning and Analytical section of many entrance examinations like CAT, XAT, SNAP, NMAT and CMAT. In these types of questions, one needs to find the relation between family members using the family tree. Hence, this topic tests the analytical skills of the students and their approach towards solving questions with diagrams instead of calculations. This topic is relatively on the easy side and the frequency of the questions coming in CAT exam is very less. However, we cannot completely ignore this topic as there is no definite syllabus for CAT Logical Reasoning and Data Interpretation.
