CUET-UG के लिए लघुगणक (Logarithms) की तैयारी कैसे करें?

Expected Weightage

The Common University Entrance Test (CUET) for Mathematics includes Logarithms (लघुगणक) as part of its syllabus. Below is an analysis of the marking pattern and chapter-wise weightage for Logarithms based on the last three years (2022–2024):

1. CUET Mathematics Exam Pattern (2022–2024)

  • Total Questions: 50 (out of which 40 must be attempted)
  • Marks per Question: +5 for correct, -1 for incorrect
  • Total Marks: 200 (40 × 5)
  • Duration: 45 minutes

2. Logarithms (लघुगणक) Weightage in CUET (2022–2024)

YearNo. of QuestionsMarks Weightage
20242–310–15
2023210
20221–25–10
  • Average Weightage: ~5–10 marks per year (~2–3 questions).
  • Difficulty Level: Moderate (mostly formula-based, with some application questions).

3. Topic-wise Breakdown of Logarithm Questions

Logarithm questions in CUET generally cover: - Basic Properties (log identities, change of base rule) – 40% - Equations Inequalities (solving log equations) – 30% - Applications (exponential growth/decay, compound interest) – 20% - Graphs Characteristics (domain, range, behavior) – **10%

4. Comparison with Other Chapters

Logarithms is a moderate-weightage chapter compared to: - High-Weightage Chapters: Algebra (20–25 marks), Calculus (15–20 marks), Probability (10–15 marks). - Similar-Weightage Chapters: Matrices (5–10 marks), Trigonometry (5–10 marks).

5. Expected Trend for 2025

  • Likely to remain 2–3 questions (10–15 marks).
  • More focus on application-based problems (e.g., growth models, pH calculations).

6. Preparation Tips

  • Revise Key Formulas:
  • $ \log(ab) = \log a + \log b $
  • $ \log\left(\frac{a}{b}\right) = \log a - \log b $
  • $ \log(a^n) = n \log a $
  • Change of base: $ \log_b a = \frac{\log_k a}{\log_k b} $
  • Practice Previous Year Questions (PYQs) from CUET and NCERT.
  • Solve MCQs on logarithmic equations inequalities.

Conclusion

Logarithms is a small but consistent part of CUET Mathematics (~5–10 marks/year). Focus on basic properties and applications for quick scoring. If you master this chapter, it can help in securing easy marks within less time.
