Dreaming of a Station Master or Goods Guard post in Indian Railways? The RRB NTPC exam is your big ticket to a secure future. But to get there, you must master the General Intelligence and Reasoning section. One topic that often confuses students is Blood Relations.

You might feel like skipping it to save time. But here is the good news: You don’t need to be a genius to solve this. Blood Relation questions are just logical puzzles. If you learn the simple trick of drawing a “Family Tree,” you can solve these questions in just 20 seconds. In this blog, we have provided the exam-level blood relation questions for RRB NTPC in a PDF that you can download for free.

How to Prepare Blood Relations Easily?
Here are the tips that will help you solve blood relation questions easily.
- Break the Sentence: In “Pointing to…” questions, always break the sentence into small parts. Start decoding from the word “My” (e.g., “My mother,” then “Her father”). This connects the dots instantly.
- Draw, Don’t Imagine: Always draw the Family Tree diagram on your rough sheet. Holding relations in your head leads to confusion.
- Don’t Assume Gender: If a name is “Suman” or “Kamal,” don’t assume they are male or female unless the question says “He” or “She.” RRB often sets traps here!
- Practice Coded Relations: Questions like “A + B means A is father…” are becoming very popular in Railway exams. Practice substituting symbols quickly.
- Attempt Topic Tests: Reading is not enough. You must solve. Attempt our Free Topic Tests to see if you can solve these in under 40 seconds.
