SSC CGL 2025 Reasoning Classes | SSC CGL 2025 Reasoning Coded Blood Relation | By Sahil Tiwari Sir

Introduction

This tutorial is designed to help you master the reasoning section of the SSC CGL 2025 exam, focusing specifically on Coded Blood Relations. Understanding coded blood relations is essential for answering questions quickly and accurately, which can greatly enhance your exam performance. This guide will provide you with clear steps, concepts, and tips to improve your skills in this area.

Step 1: Understand Coded Blood Relations

• Familiarize yourself with basic blood relation terminology:
  • Father: Male parent
  • Mother: Female parent
  • Brother: Male sibling
  • Sister: Female sibling
  • Son: Male child
  • Daughter: Female child
  • Grandfather: Father of a parent
  • Grandmother: Mother of a parent
• Recognize that coded relations will often use symbols or letters to represent familial relationships. For example:
  • A + B = A is the father of B
  • A - B = A is the mother of B
  • A × B = A is the brother of B
  • A ÷ B = A is the sister of B

Step 2: Learn Common Codes and Their Meanings

• Create a reference chart for quick recall of common codes:
  • +: Father
  • -: Mother
  • ×: Brother
  • ÷: Sister
  • =: Spouse
• Practice translating coded statements into standard family trees. For example:
  • If the code states "A + B - C", it translates to "A is the father of B, and B is the mother of C."

Step 3: Build Family Trees

• When faced with a coded blood relation question:
  • Draw a simple family tree based on the relationships provided.
  • Start with the first relation and build outwards, adding each subsequent member as you interpret the codes.
• Use different symbols for different generations to avoid confusion.

Step 4: Solve Practice Questions

• Apply your knowledge by solving practice questions related to coded blood relations.
  • Use sample papers or online resources to find relevant questions.
  • Time yourself to improve speed and accuracy.

Step 5: Use Shortcuts and Tricks

• Memorize certain shortcuts to improve efficiency:
  • If the question involves multiple generations, focus on the immediate relations first before considering extended family.
  • Pay attention to keywords in questions that indicate direction (e.g., "sister of", "father of").

Conclusion

Mastering coded blood relations is a critical skill for success in the SSC CGL exam. By understanding the codes, building family trees, and practicing regularly, you can significantly enhance your problem-solving speed and accuracy. As your next step, engage in regular practice with timed quizzes and utilize resources like the SSC MahaPack for comprehensive study materials. Good luck with your preparation!
