How to prepare for संख्या प्रणाली (Number System) for CUET-UG ?

Expected Weightage

The Common University Entrance Test (CUET) for संख्या प्रणाली (Number System) has shown a consistent but moderate weightage over the last three years (2022-2024). Below is an analysis of the chapter-wise weightage and marking pattern based on past trends:

1. Overall Weightage in CUET (Mathematics/Applied Maths)

  • Number System typically contributes 8-12% of the total questions in the Mathematics/Applied Mathematics section.
  • The section usually has ~5-8 questions (out of 50), varying slightly each year.

2. Chapter-wise Breakdown (Number System Topics)

The संख्या प्रणाली section includes subtopics like:

  • Types of Numbers (Natural, Whole, Integers, Rational, Irrational, Real, Complex)
  • Divisibility Rules & LCM/HCF
  • Decimal Expansions & Terminating/Non-Terminating Decimals
  • Prime Numbers & Factorization
  • Modular Arithmetic (Remainders)
  • Number Line & Representation

Weightage Distribution (2022-2024)

Topic202220232024 (Expected)
Types of Numbers2-3 Q2 Q2-3 Q
LCM & HCF1-2 Q2 Q1-2 Q
Divisibility Rules1 Q1 Q1 Q
Prime Numbers1 Q1 Q1 Q
Decimal Expansions1 Q1 Q1 Q
Modular Arithmetic0-1 Q1 Q1 Q

3. Marking Scheme

  • Correct Answer: +5 marks
  • Incorrect Answer: -1 mark (Negative marking)
  • Unattempted: 0 marks

4. Difficulty Level & Trends

  • 2022: Mostly easy-moderate (direct formula-based questions).
  • 2023: Slightly tougher (application-based, e.g., word problems on LCM/HCF).
  • 2024 (Expected): Similar to 2023, with a mix of conceptual and problem-solving questions.

5. Preparation Tips

  • Focus on LCM/HCF, divisibility rules, and prime factorization (highly recurring).
  • Practice real-world problems (e.g., finding numbers when divided by x leaves remainder y).
  • Revise decimal expansions (terminating vs. non-terminating).

Conclusion

  • Number System is a moderately important chapter (~10% weightage).
  • LCM/HCF & Types of Numbers are the most frequently tested topics.
  • Expect 5-8 questions with a mix of theory and application.
