No, not at all! The reasoning section in CBT 1 is very basic. The blood relation questions can be solved easily if you draw a simple family tree diagram on your rough sheet.
Out of the 25 questions in the Reasoning section, you can comfortably expect 1 to 2 direct questions from Blood Relations.
Absolutely not! Blood relations is a purely logical topic. There are no math formulas here. You just need to know basic family connections like uncle, aunt, niece, and nephew.
If the question says “A is the child of B,” you cannot assume A is a boy or a girl. In such cases, if the options ask for the exact relation, look for options like “Son or Daughter” or “Cannot be determined.”
Yes, simple coded relations (like A+B means A is father) are sometimes asked. But they are very short and direct, not long and confusing like banking exams.
