RBSE Class 10 Math 2026: 90-100 Most Important Chapter-Wise Questions

Real Numbers: Key Concepts

Prime factorization and HCF/LCM dominate this chapter. Expect questions like:

"Find the sum of exponents in prime factorization of 196"
"Identify irrational numbers from given options"
"If p and q are co-prime, their HCF is always..."
Expert tip: Master Euclid’s division lemma—it’s foundational for 30% of chapter questions. After analyzing previous papers, questions on prime factorization patterns appear yearly.

Practice Essentials

HCF of 96 and 404 by prime factorization
LCM of 72 and 120
Sum of exponents for 144’s prime factors

Polynomials & Linear Equations

Polynomial Zeroes and Degrees

Critical question types:

"If x=2 is zero of 2x² + x + k, find k"
"Degree of polynomial p(x)=3x(x-4)"
Form quadratic polynomials with given sum/product of zeroes (e.g., sum=3, product=2)

Pair of Linear Equations

Section A highlights:

Graphical solution questions
Algebraic representation (e.g., "7 pencils + 5 pens = ₹29")
Number problems ("One number is three times another...")

Quadratic Equations & Trigonometry

Solving Quadratics

Must-prepare methods:

Factorization ("Solve x²-5x+6=0")
Discriminant application ("Find k for equal roots")
Shridharacharya formula problems

Trigonometry Foundations

High-yield topics:

Value calculations (e.g., sin²30° + cos²30°)
Trigonometric identities
Exam pattern insight: 55% of trigonometry questions test identity applications. Practice proofs thoroughly.

Geometry & Statistics Mastery

Triangles and Circles

Chapter 6 priorities:

Triangle congruence criteria (ASA, SAS)
Circle theorems (tangents, segments)
Exclusive tip: Diagram-based questions carry 70% weight. Sketch figures while solving.

Statistics & Probability

Key focus areas:

Mean/median/mode calculations (table-based)
Probability dice/card problems
Critical reminder: RBSE consistently asks probability questions with real-life scenarios. Practice "coin toss in multiple trials" variations.

Action Plan & Resources

Immediate checklist:

Solve all chapter-wise MCQs shown
Practice prime factorization speed drills
Verify trigonometric identities daily
Attempt 3 graph-based equations
Review mean/median problem formats
