Blood Relation Questions for SSC CHSL, Download Free PDF & Practice Now

Preparing for the SSC CHSL exam? You are likely aiming for a secure government job as an LDC or DEO. To get there, you need to score high in the Tier 1 exam. In the General Intelligence (Reasoning) section, there is one topic that is both interesting and confusing—Blood Relations. We all know who our “Uncle” or “Aunt” is in real life. But when the exam asks, “Pointing to a lady, a man said, ‘Her mother is the only daughter of my mother-in-law,'” our brain gets twisted. You don’t need to be a genius to solve these. Blood Relation questions are just a puzzle. If you learn how to draw a simple “Family Tree,” you can solve even the hardest question in less than 30 seconds. To help you practice, we have selected the most important Blood Relation questions asked in previous SSC CHSL exams. We have compiled them into a Free PDF that you can download below.

Why is Blood Relation Important for SSC CHSL?

In the SSC CHSL Tier 1 exam, Reasoning has 25 questions. You can easily expect 2 to 3 questions from Blood Relations.

• 100% Accuracy: Unlike English or GK where you might be unsure, in Blood Relations, once the diagram is drawn, the answer is definite.
• Types of Questions: You mostly get three types:
  1. Pointing/Introducing: (Pointing to a photo…)
  2. Family Tree: (A is the father of B, B is the sister of C…)
  3. Coded Relations: (A + B means A is the father of B…)

Important Concepts: The “Family Tree” Method

Don’t try to solve these questions in your head. You will get confused. Use symbols:

• Male: Draw a Box [ ] or (+)
• Female: Draw a Circle ( ) or (-)
• Married Couple: Use a double line (=)
• Siblings: Use a single line (—)
• Generations: Use a vertical line (|)

How to Prepare Blood Relations for SSC CHSL?

It’s easy to get lost in words like “Brother-in-law” and “Paternal Aunt.” Follow these simple tips:

• Draw, Don’t Imagine: Always draw the Family Tree diagram. Never try to hold all the relations in your head.
• Break the Sentence: In “Pointing to…” questions, break the sentence into small parts. Start from the word “My” (e.g., “My mother,” then “Her father”). This makes it easy to connect the dots.
• 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.” This is a common trap!
• Practice Coded Relations: SSC CHSL is asking more “A + B” type questions lately. Practice substituting the symbols quickly.
• Attempt Topic Tests: Once you finish the PDF, test your speed. Attempt Free Topic Tests to see if you can solve these in under 40 seconds.
