Bihar Board Class 10 Solutions – Complete BSEB Matric Exam Answers for All Subjects

The Bihar Board Matric examination sits at a crossroads in every student's life. It is the first result that follows a student into adulthood — onto college applications, scholarship forms, and job documents. It is the result that families in Araria and Aurangabad, in Madhubani and Munger, in Saran and Sitamarhi wait for with a mixture of pride and anxiety. And it is the result that, more than almost any other factor, shapes what happens next for a Bihar Board student.

What separates students who score well in the Bihar Board Matric examination from those who score below their potential is rarely the amount of time spent studying. Most Bihar Board Class 10 students study hard. The difference is almost always in the quality of what gets written on the answer sheet.

This page addresses that difference directly.

Here you will find complete Bihar Board Class 10 solutions for every major subject in the Matric curriculum — written to examination standard, structured the way Bihar Board examiners expect, and calibrated precisely to the mark allocations of the Bihar Board Matric paper. These are not summaries or notes. These are Matric exam answers that show, in concrete detail, what a complete, full-mark response looks like for every question type across every subject.

Every BSEB 10th solution on this page has been developed with the Bihar Board Matric marking scheme in mind. The goal is not just to show students what the correct answer is — it is to show them how to write it in a way that earns every mark available.

One note for students currently in Class 9: this page is dedicated entirely to Bihar Board Class 10 Matric solutions. Class 9 solutions are available on our dedicated Class 9 page. Every answer and solution here is written for the Bihar Board Matric examination curriculum. Students planning ahead for Class 11 will also find that developing strong answer-writing habits through these solutions creates a foundation that Class 11 and Class 12 Bihar Board examinations build directly upon.

The Bihar Board Matric Paper — What It Actually Looks Like

Before diving into subject-specific solutions, understanding the architecture of the Bihar Board Matric examination paper changes everything about how a student prepares. Most Class 10 students in Bihar have a vague sense that there are objective questions and written questions — but the precise structure, and what it means for preparation strategy, is something far fewer understand clearly.

The Bihar Board Matric paper for most subjects is divided into two sections of equal weight. The first section contains seventy objective questions — multiple choice, one mark each, totalling seventy marks. The second section contains subjective questions — a combination of short answer and long answer questions — totalling the remaining seventy marks of the one hundred and forty mark paper.

This equal split has a preparation implication that many students miss entirely. The objective section cannot be prepared for selectively. Every chapter of every subject contributes questions to the objective section. A student who covers eight chapters deeply and leaves two chapters untouched will encounter questions from those two uncovered chapters in the objective section and have no basis for answering them. Objective preparation demands full coverage — every chapter, every subject, no exceptions.

The subjective section is where the quality of written answers determines results. Short answer questions carry two to three marks and expect focused, precise written responses. Long answer questions carry five to six marks and expect comprehensive treatments with diagrams, derivations, or extended explanations where the subject demands. Understanding these expectations — and practising answers that meet them — is what the Bihar Board Class 10 prashn uttar solutions on this page are designed to support.

Why Class 10 Solutions Require a Different Approach from Class 9

Students who performed well in Class 9 school examinations sometimes find that their Class 9 approach does not automatically translate into strong Bihar Board Matric performance. The reason is structural, not a matter of effort.

Class 9 school examinations are set and marked by school teachers who know their students, who have taught the content themselves, and who mark with a degree of contextual generosity that a centralised board examination cannot offer. The Bihar Board Matric examination is marked by examiners who have never met the student, who are following a strict marking scheme, and who are processing large volumes of papers in a limited time.

This difference means that the slightly vague answer that earned eight out of ten in a Class 9 school test — the answer that captured the general idea but was imprecise in its terminology — will earn four out of ten in the Matric examination, because the marking scheme does not award marks for the general idea. It awards marks for the specific elements it specifies: the correct definition, the correct formula, the correctly labelled diagram, the correct number of developed points.

The Class 10 prashn uttar solutions on this page are written to Matric examination standard — which is stricter, more precise, and more demanding than Class 9 school examination standard. Working with these solutions throughout Class 10 builds the answer-writing discipline that the Matric examination requires.

Science — The Subject Where Diagrams and Definitions Share Equal Billing

Bihar Board Matric Science is a combined paper covering Physics, Chemistry, and Biology content within a single examination. This combined structure means that the Science paper draws questions from across all three scientific disciplines — and a student who has prepared only the Biology chapters, or only the Chemistry chapters, will find roughly two-thirds of the paper inadequately prepared for.

The chapters that consistently generate the most subjective questions in Bihar Board Matric Science papers — based on examination pattern analysis — are chemical reactions and equations, acids bases and salts, metals and non-metals, life processes, control and coordination, light, electricity, and our environment. Within these chapters, certain question formats appear with enough regularity to be treated as near-certain examination content.

Chemistry Chapters — Writing Answers That Show Chemical Understanding

For chemical reactions and equations, the most important answer-writing discipline is writing balanced chemical equations correctly. A Bihar Board Matric examiner marking a Chemistry answer is checking three things simultaneously in every equation: correct chemical formulae for all reactants and products, correct balancing of atoms on both sides, and correct state symbols where required. A student who writes correct formulae but incorrect balancing, or correct balancing but missing state symbols, loses marks at each point of error.

For acids, bases, and salts — a chapter that appears in some form in virtually every Bihar Board Matric Science paper — answers must clearly distinguish between the properties of acids and bases using both the Arrhenius definition and the observable properties tested in the laboratory. The use of indicators, the pH scale, and the neutralisation reaction must each be addressed precisely. Vague answers that say acids "taste sour" and bases "feel slippery" without chemical explanation will earn basic marks but not full marks.

Biology Chapters — Where Labelled Diagrams Are Non-Negotiable

Life processes and control and coordination are the two Biology chapters that generate the most diagram-based questions in Bihar Board Matric Science papers. For life processes, the diagrams of the human digestive system, the human respiratory system, and the human excretory system each appear regularly. For control and coordination, the diagram of a reflex arc and the structure of a neuron are examined with high frequency.

Every Biology diagram answer in Bihar Board Matric should meet the same four standards: drawn clearly enough to be legible, proportioned to reflect actual biological relationships, completely labelled with every significant structure named, and labels written in a neat line without crossing over the diagram. A diagram where label lines cross each other or where labels are written across structures rather than alongside them signals carelessness — and carelessness costs marks in a Matric examination where examiners are following a detailed marking scheme.

Physics Chapters — Formulas, Derivations, and Ray Diagrams

Light and electricity are the two Physics chapters that carry the highest mark allocation in Bihar Board Matric Science subjective papers. For light, ray diagram questions — showing the formation of images by convex and concave mirrors, and by convex and concave lenses — are among the most predictable questions in the entire Matric Science paper. A student who has practised all four standard ray diagram constructions repeatedly, until they can draw them accurately without reference, has secured reliable marks in one of the most consistent question areas of the paper.

For electricity, Ohm's law derivation and the calculation of equivalent resistance in series and parallel circuits are the foundational answer types. Every Ohm's law answer should include a clear circuit diagram, the definition of resistance, the statement of Ohm's law as both a formula and a relationship, and a numerical application. An electricity answer without a circuit diagram is structurally incomplete by the standards of the Bihar Board Matric marking scheme.

Mathematics — Where Every Step Is a Mark Waiting to Be Earned

Bihar Board Matric Mathematics is the subject where the relationship between working and marks is most direct and most consequential. In every other subject, the final answer carries a significant proportion of the available marks. In Mathematics, the working carries most of them — which means the way a student writes their solution matters as much as the correctness of the answer they arrive at.

The chapters that generate the most subjective questions in Bihar Board Matric Mathematics papers are real numbers, polynomials, pair of linear equations in two variables, quadratic equations, arithmetic progressions, triangles, coordinate geometry, introduction to trigonometry, applications of trigonometry, circles, areas related to circles, surface areas and volumes, statistics, and probability. Together, these chapters cover the complete range of Bihar Board Matric Mathematics content, and preparation that skips any of them creates vulnerabilities in both the objective and subjective sections.

The Six-Step Solution Structure — Applied to Every Problem

The most important answer-writing discipline in Bihar Board Matric Mathematics is the six-step solution structure, applied without exception to every problem regardless of how simple it seems. Step one: write what is given. Step two: write what is to be proved or found. Step three: state the relevant theorem, formula, or method. Step four: show the working, step by step, with every algebraic manipulation written out. Step five: arrive at the result. Step six: write a concluding statement — "Hence proved" for proof questions, or "Therefore [quantity] = [value with unit]" for calculation questions.

This six-step structure is not bureaucratic overhead. Each component within it corresponds to marks in the Bihar Board Matric Mathematics marking scheme. Step three — stating the relevant theorem or formula before applying it — is a mark-earning step that most students skip because it feels obvious. It is not obvious to an examiner who cannot see inside the student's mind. Writing it explicitly earns the mark. Not writing it loses it.

Trigonometry — The Chapter That Rewards Consistent Practice

Trigonometry — both the foundational chapter and its applications — is consistently among the highest mark-carrying chapters in Bihar Board Matric Mathematics. Trigonometric identities, trigonometric ratios for standard angles, and height-and-distance application problems together generate a significant proportion of the Mathematics subjective section.

For trigonometric identity proofs — a question type that appears in virtually every Bihar Board Matric Mathematics paper — the answer must begin with one side of the identity written at the top of the working, proceed through a sequence of substitutions and simplifications using identities stated explicitly at each step, and arrive at the other side of the identity written at the bottom with "= RHS" or "LHS = RHS" as the concluding statement. Working that starts from both sides simultaneously and meets in the middle is not accepted in Bihar Board Mathematics marking — the working must proceed from one side to the other in a single direction.

Social Science — Four Books, Four Answer Approaches

Bihar Board Matric Social Science is not one subject — it is four distinct disciplines bound between the covers of four separate textbooks: History, Geography, Political Science, and Economics. Each discipline has its own answer-writing logic, and treating them all the same — writing historical narrative for a Geography question, or writing factual description for a Political Science analysis question — is one of the most common and costly errors in Bihar Board Matric Social Science papers.

History — Narrative Built on Evidence

Bihar Board Matric History covers the rise of nationalism in Europe, nationalism in India, the making of a global world, the age of industrialisation, print culture, and novels and society. Long answer questions in History expect a developed narrative — not a list of facts but a coherent account of how one thing led to another, with dates and names placed within the narrative rather than listed separately.

The most productive answer-writing approach for Bihar Board Matric History is what experienced Social Science teachers across Bihar describe as the story approach — treating the historical process as a story with a beginning, a development, and an outcome, and writing the answer in a way that traces that story clearly. An answer on the Non-Cooperation Movement that begins with the reasons for its launch, traces its major phases and participants, and explains why it was suspended tells a coherent historical story that examiners recognise and reward.

Geography — Resources, Development, and Precise Factual Content

Bihar Board Matric Geography covers resources and development, forest and wildlife, water resources, agriculture, minerals and energy resources, manufacturing industries, lifelines of national economy, and population. Geography answers are heavily factual — they require specific names, locations, types, and classifications stated accurately.

Map work is an integral part of Bihar Board Matric Geography, and map questions appear in the subjective section with notable frequency. Rivers, mountain ranges, soil types, agricultural regions, mineral deposits, industrial centres, and transport routes must be located correctly on outline maps of India. Students who treat map practice as optional — something to be done if time permits — consistently find that map questions cost them marks they cannot recover through additional writing in other sections.

Political Science — Institutions, Processes, and Democratic Values

Bihar Board Matric Political Science covers power sharing, federalism, democracy and diversity, gender religion and caste, popular struggles and movements, political parties, outcomes of democracy, and challenges to democracy. These are primarily conceptual chapters, and Political Science answers are assessed on the quality of conceptual explanation — the ability to explain what power sharing means, why federalism matters, what makes a political party democratic — rather than on factual recall.

For distinction questions in Political Science — "distinguish between federal and unitary governments," "what is the difference between a pressure group and a political movement" — the answer must go beyond naming the two things being distinguished and must explain the conceptual difference between them in terms that demonstrate genuine understanding.

Economics — Data, Development, and Sectoral Analysis

Bihar Board Matric Economics covers development, sectors of the Indian economy, money and credit, globalisation, and consumer rights. Economics answers combine factual content with simple analytical framework, and the most effective approach is to structure answers around the economic concept being asked about — development as a multidimensional concept, the formal and informal sectors as distinct economic environments, credit as a double-edged tool for rural households.

For development questions — which appear consistently in Bihar Board Matric Economics papers — the answer must move beyond GDP as the sole measure and explicitly address the limitations of income-based development indicators, the role of human development indices, and the difference between average income and distribution of income. Answers that discuss development purely in terms of income growth are structurally incomplete by the standards of the Bihar Board Matric marking scheme for this chapter.

Hindi — Three Sections, Three Writing Voices

Bihar Board Matric Hindi — covering Godhuli Bhag 2 and Varnika Bhag 2 — is examined across three distinct sections: prose and poetry from the prescribed readers, grammar, and composition writing. Each section requires a different register and a different answer approach, and many Bihar Board Hindi students lose marks by applying the same voice across all three.

Prose and poetry answer questions require academic engagement with the text — explaining what the author means, what the poet is expressing, what literary devices are employed, and what the passage reveals about its social or human context. These are not questions about personal opinion. They are questions about textual meaning, and answers that respond with personal opinion rather than textual analysis will be marked accordingly.

Grammar questions require precision above all else. The correct application of sandhi, samas, karak, and tense forms is checked against a marking scheme that expects exact answers. Partial answers — the right general category but the wrong specific type — earn partial marks at best.

Composition writing — essays, letters, and paragraph writing — rewards formal register, organised structure, and correct punctuation. An essay answer that wanders without a clear opening, development, and conclusion, or a letter that omits the correct format elements — date, address, subject line, salutation, closing — will be penalised for structural incompleteness regardless of the quality of the language within it.

English — Reading, Writing, and Grammar in One Paper

Bihar Board Matric English covers Panorama — the prescribed prose and poetry reader — alongside grammar and writing sections. For students in Bihar who have studied primarily in Hindi medium throughout their schooling, the English paper presents a distinct challenge: demonstrating sufficient English language proficiency to earn marks across all three sections.

Reading comprehension answers in Bihar Board Matric English must be written in complete sentences drawn from the text and rephrased in the student's own words. Copying sentences directly from the passage without any rephrasing is penalised in Bihar Board English marking. Answers must demonstrate that the student has understood the passage — not just located the relevant sentence.

Writing section answers — letters, applications, notices, and paragraphs — are assessed on format correctness alongside language quality. A job application that contains correct English but omits the date, the recipient's address, the subject line, or the formal closing will lose marks for every missing format element. Practising format-correct writing throughout Class 10 — not just in the week before the examination — is the only preparation that produces reliable results under examination conditions.

The Objective Section — Preparing for Half of All Available Marks

The fifty percent weight given to the objective section in Bihar Board Matric papers makes it the single most strategically important component of Matric preparation. Yet it is also the component that most students prepare for least systematically.

Effective objective preparation for Bihar Board Matric requires three things that most students do not do consistently. First, full syllabus coverage — every chapter of every subject must be read carefully enough that the key definitions, classifications, names, dates, formulas, and relationships are available for recall. Second, practice under timed conditions — the objective section gives approximately one minute per question, and students who have not practised answering MCQs under time pressure consistently find that they run out of time before completing the section. Third, error analysis — after every practice session, wrong answers must be traced back to their source — was it a knowledge gap, a misreading, or a confusion between two similar concepts? — and that source must be addressed before the next practice session.

Answer Format Guide — What to Write for Each Mark Allocation

Two-mark answers should be four to six lines: a precise definition or statement of the concept, followed by one explanatory sentence or a simple example. No diagram required unless specifically asked.

Three-mark answers should be six to eight lines: a definition or opening statement, two developed points of explanation each in a complete sentence, and a brief concluding line or example.

Five-mark answers should be twelve to fifteen lines: a structured opening, three to four developed explanatory points each addressing a distinct aspect of the question, a diagram or formula or example where relevant, and a clear conclusion.

Six-mark answers should be sixteen to twenty lines: a comprehensive treatment that covers the topic from multiple angles, includes all technical elements the marking scheme expects — diagrams, derivations, worked examples — and concludes with a statement that directly answers the question asked.

Frequently Asked Questions

Q1. Where can I find BSEB 10th solutions PDF for all subjects?

Complete BSEB 10th solutions PDF for all Matric subjects — Science, Mathematics, Social Science, Hindi, English, and third language subjects — are available on this page. The subject-wise access links are provided above, organised chapter by chapter. Every solution is written to Bihar Board Matric examination standard and is available for free. Download or access the solutions directly for the subjects you need.

Q2. Are Bihar Board Class 10 prashn uttar available in Hindi medium?

Yes. Bihar Board Class 10 prashn uttar are available in both Hindi and English medium on this page. Since the majority of Bihar Board Matric students appear for their examination in Hindi medium, the Hindi medium solutions use the same terminology and language register as the Bihar Board prescribed Hindi medium textbooks — ensuring that the solutions match the language and vocabulary that Bihar Board Hindi medium examiners expect to see in answer sheets.

Q3. How is the Bihar Board Matric exam different from other state board Class 10 exams?

The Bihar Board Matric examination has a distinctive structure that sets it apart from many other state board Class 10 examinations. The equal fifty-fifty split between the objective section and the subjective section — with seventy marks each — means that success in the Bihar Board Matric examination requires both breadth of coverage for the objective section and depth of answer quality for the subjective section simultaneously. Many state boards weight the subjective section more heavily, which allows students to compensate for weaker objective performance through strong written answers. In Bihar Board Matric, this compensation is not available — both sections must be prepared thoroughly and independently.

Q4. Which subject is the most difficult in Bihar Board Class 10 and how can solutions help?

Mathematics and Science are consistently rated the most challenging subjects by Bihar Board Class 10 students — Mathematics because of its requirement for step-by-step solution discipline, and Science because of its combination of three scientific disciplines in one paper. Bihar Board Class 10 solutions help with both subjects in a specific way: they model the exact structure of a complete, mark-earning answer. For Mathematics, seeing a correctly structured solution — with all working shown, all formulas stated, and all units included — gives students a template they can replicate. For Science, seeing how diagram answers are structured and how chemical equations are written and balanced provides a standard to aim for in their own answers.

Q5. Can Bihar Board Class 10 solutions be used for Bihar Board Class 9 preparation too?

Bihar Board Class 10 solutions are written specifically for the Matric curriculum, which is more advanced than the Class 9 curriculum in every subject. However, Class 9 students who study Bihar Board Class 10 solutions for the same chapters — particularly in Science and Mathematics, where Class 9 and Class 10 content is closely connected — will develop both a preview of what Class 10 demands and an answer-writing standard to aspire to. The answer-writing approach modelled in Matric exam answers — the step-by-step solution discipline for Mathematics, the diagram quality for Science, the structured narrative for Social Science — is equally applicable at Class 9 level and consistently produces better Class 9 school examination results when adopted early.

Q6. Do Bihar Board Matric solutions cover the objective section as well?

Yes. The resources on this page cover both the objective and subjective sections of the Bihar Board Matric paper. For the objective section, chapter-wise MCQ banks with answer explanations are available for every subject — not just the correct answer, but an explanation of why the correct answer is correct and why the commonly confused alternatives are incorrect. This explanation-based approach to objective preparation produces stronger results than simple answer-key memorisation, because it builds the conceptual understanding that allows a student to answer MCQs on concepts they have never seen the exact question for before.

The Matric Result Starts Here — On This Page, Right Now

The Bihar Board Matric result that gets announced — that appears on the board's website, that families across Bihar refresh and check and share — is not built in the examination hall. It is built in the months before it, in the daily discipline of studying solutions, practising answers, identifying gaps, and writing with the precision and completeness that Bihar Board examiners reward.

Every student in Bihar — in every district, in every school, with every background — sits the same Matric examination. The chapters are the same. The question types are the same. The marking scheme is the same. The Bihar Board Class 10 solutions on this page are the same for every student who accesses them.

What is not the same is how each student uses them. The students who use these solutions as active preparation tools — who write answers alongside them, compare their answers against the models, identify where their answers fall short, and improve — are the students who walk into the Matric examination hall genuinely prepared for what awaits them there.

That preparation starts here.
