CBSE Class 10 General: CBSE Class 10 Previous Year Question Paper 2024 with Solutions All Subjects (2025–2026 Exam Guide)

Mastering the CBSE Class 10 General curriculum requires rigorous analysis of official past examination papers. As students gear up for the 2025 and 2026 board exam 10 cycle, reviewing the CBSE Class 10 Previous Year Question Paper 2024 with Solutions All Subjects serves as the ultimate benchmark. The 2024 papers set a distinct standard by heavily integrating competency-based evaluations, assertion-reason items, and multi-disciplinary real-world case studies across Mathematics, Science, Social Science, and English.

Solving these solved papers bridges the gap between theoretical textbook reading and the exact answer presentation required by Central Board examiners to award full step marks.

Overview of the 2024 CBSE Class 10 Question Paper Pattern

The 2024 examination papers operationalized the National Education Policy (NEP) recommendations with a reformed question typology. Across all major subjects, the 80-mark theory papers maintained the following structural weightage:

• 50% Competency-Focused Questions: Multiple-choice questions (MCQs), case-based scenario questions, source-based data interpretation, and integrated application problems.
• 20% Select Response Questions: Objective MCQs and Assertion-Reasoning formats testing conceptual precision.
• 30% Constructed Response Questions: Short Answer (2 and 3 marks) and Long Answer (5 marks) questions demanding structured proofs, derivations, diagrams, and analytical essays.

Subject-Wise Analysis & Core Concepts from 2024 Papers

1. Mathematics (Standard Code 041 & Basic Code 241)

The 2024 Mathematics paper placed heavy emphasis on algebraic modeling, coordinate geometry in practical navigation, and geometric proofs. Key focus areas included:

• Quadratic Equations & Arithmetic Progressions: Real-world rate and work problems solvable via the standard quadratic formula:
  x = [-b ± √(b2 - 4ac)] / (2a)
  and AP nth term / summation formulas: an = a + (n - 1)d, Sn = (n/2)[2a + (n - 1)d].
• Trigonometry & Heights/Distances: Applications utilizing fundamental identities such as sin2θ + cos2θ = 1, 1 + tan2θ = sec2θ, and 1 + cot2θ = cosec2θ.
• Surface Areas and Volumes: Combination of solids (e.g., a cone surmounted on a hemisphere) requiring exact volume and curved surface area derivations.

2. Science (Code 086)

The 2024 Science paper tested conceptual interconnections across Physics, Chemistry, and Biology:

• Chemical Reactions & Acids/Bases: Stoichiometric balancing, redox identification, and precipitation reactions. For example, the thermal decomposition of lead nitrate:
  2Pb(NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g)
• Electricity & Magnetic Effects: Circuit reductions applying Ohm’s Law (V = I · R), Joule’s Law of Heating (H = I2Rt), and equivalent resistance calculations for series and parallel networks:
  1/Rp = 1/R1 + 1/R2 + ... + 1/Rn
• Life Processes & Heredity: Detailed mechanisms of human excretion (structure of the nephron), double circulation in the heart, and monohybrid/dihybrid genetic ratios (3:1 and 9:3:3:1).

3. Social Science (Code 087)

The Social Science paper shifted away from rote recall toward analytical case interpretation across its four domains:

• History: The rise of nationalism in Europe and India, print culture’s impact on societal reform, and map-based identification of Indian National Congress sessions and peasant movements.
• Geography: Resource planning, multi-purpose river projects, sustainable agriculture, and major mineral/energy hub mapping.
• Political Science: Power-sharing mechanisms (horizontal vs. vertical), federalism, and the role of regional political parties in strengthening democracy.
• Economics: Formal vs. informal sources of credit, Self-Help Groups (SHGs), globalization drivers, and measuring economic development via Human Development Index (HDI) parameters.

4. English Language & Literature (Code 184)

Section A tested unseen discursive and factual passages requiring high-order inference. Section B evaluated formal letter writing and analytical paragraphs based on bar charts, pie charts, and data tables. Section C required thematic analysis and character sketches from First Flight and Footprints Without Feet.

Important CBSE 2024 Questions with Official-Standard Solutions

Question 1: Mathematics (Standard) – Trigonometric Identity Proof (3 Marks)

Question: Prove that: (sin θ - 2 sin3 θ) / (2 cos3 θ - cos θ) = tan θ

Step-by-Step Solution:

1. Step 1 (Factoring common terms): Factor out sin θ from the numerator and cos θ from the denominator:
   LHS = [sin θ (1 - 2 sin2 θ)] / [cos θ (2 cos2 θ - 1)] [1 Mark]
2. Step 2 (Using identity sin2 θ + cos2 θ = 1): Replace 1 in numerator and denominator:
   Numerator = sin θ [(sin2 θ + cos2 θ) - 2 sin2 θ] = sin θ (cos2 θ - sin2 θ)
Denominator = cos θ [2 cos2 θ - (sin2 θ + cos2 θ)] = cos θ (cos2 θ - sin2 θ) [1 Mark]
3. Step 3 (Simplification to RHS): Cancel common factor (cos2 θ - sin2 θ):
   LHS = sin θ / cos θ = tan θ = RHS. Hence Proved. [1 Mark]

Question 2: Science (Physics) – Equivalent Resistance Calculation (3 Marks)

Question: A uniform metallic resistance wire of length L and total resistance R is cut into 4 equal pieces. These four pieces are then connected in parallel. If the equivalent resistance of this parallel combination is R′, calculate the ratio R / R′.

Step-by-Step Solution:

1. Step 1 (Resistance of each segment): Since resistance is directly proportional to length (R ∝ L), cutting the wire into 4 equal segments gives each segment a resistance of r = R / 4. [1 Mark]
2. Step 2 (Parallel combination formula): For 4 identical resistors of value r connected in parallel:
   1 / R′ = (1 / r) + (1 / r) + (1 / r) + (1 / r) = 4 / r
   Substitute r = R / 4:
   1 / R′ = 4 / (R / 4) = 16 / R ⇒ R′ = R / 16 [1 Mark]
3. Step 3 (Computing the ratio):
   R / R′ = R / (R / 16) = 16 / 1 = 16:1. [1 Mark]

Question 3: Social Science (Economics) – Credit & Development (3 Marks)

Question: “Cheap and affordable credit is crucial for a country’s development.” Justify this statement with three valid arguments based on the NCERT curriculum.

Answer (Official Marking Rubric):

• Expansion of Agriculture & Small-Scale Enterprise: Affordable loans allow farmers to purchase high-yielding variety (HYV) seeds, fertilizers, and irrigation equipment without falling into debt traps, thereby increasing agricultural output and national food security. [1 Mark]
• Encouraging Entrepreneurship and Employment: Lower interest rates enable small business owners and cottage industries to invest in capital machinery, scale production, and generate new employment opportunities. [1 Mark]
• Prevention of Debt Traps: Reliance on informal moneylenders with exorbitant interest rates drains borrower income. Formal, low-cost credit ensures borrowers retain surplus income to reinvest and improve household living standards. [1 Mark]

How to Prepare for This Topic and Maximize Board Exam Scores

Practicing previous year question papers should not be a passive reading exercise. Follow this structured 4-step preparation protocol:

1. Timed 3-Hour Simulation: Sit in an isolated environment with a physical copy of the 2024 paper and an answer sheet. Dedicate the mandatory initial 15 minutes exclusively to reading and selecting internal choice questions.
2. Step-Wise Self-Assessment: Cross-check your responses directly against the official CBSE marking scheme. Note where you lost half-marks (e.g., missing units in physics problems, missing state symbols in chemical equations, or inadequate labels in diagrams).
3. Analyze Recurring Competency Themes: Identify repeated question archetypes across sets (e.g., case-based questions on coordinate geometry or extract-based poems) to reinforce weak textbook chapters.
4. Refine Answer Presentation: Use bullet points for Social Science theoretical explanations, underline key scientific terms in Science, and write explicit formulas before numerical substitutions in Mathematics.
