Theory base of accounting is the set of principles, assumptions, concepts, and standards that guide how business transactions are recorded. It helps accountants prepare reliable financial statements using rules such as GAAP, dual aspect, matching, and consistency.
A business does not record transactions randomly. Every entry in the books follows a rule, reason, and purpose. Important Questions Class 11 Accountancy Chapter 2 help students understand this logic behind accounting. Chapter 2, Theory Base of Accounting, explains why financial statements need uniform rules, why the owner and business are treated separately, why revenue is recorded when earned, and why losses are provided before profits are recognised. For CBSE 2026, this chapter is important for short answers, long answers, concept identification, accounting equation questions, and GST-based application questions. The answers below follow the NCERT Class 11 Accountancy Chapter 2 scope for 2026-27.
Key Takeaways
- GAAP gives accounting a common language: It helps every business record and report transactions using accepted rules.
- Accounting concepts explain the logic behind entries: Business entity, going concern, cost, dual aspect, matching, consistency, and conservatism show why accounts are prepared in a particular way.
- Accounting standards and GST connect theory with business practice: ICAI standards improve comparability, while GST explains tax treatment through CGST, SGST, and IGST.

Theory Base Of Accounting Class 11 Important Questions
The theory base of accounting explains the thinking behind every accounting rule. It gives accounting a stable structure, so financial information remains useful for owners, managers, creditors, investors, and tax authorities.
These theory base of accounting class 11 questions help students revise the chapter from the ground level.
Q1. What Is Theory Base Of Accounting?
Theory base of accounting means the principles, concepts, rules, guidelines, and standards used for recording and reporting business transactions.
It helps accountants prepare financial statements in a uniform and consistent manner. Without a theory base, accounting information may become unreliable and difficult to compare.
Q2. Why Is Theory Base Of Accounting Necessary?
Theory base of accounting is necessary because users need reliable and comparable financial information.
Investors may compare profit across firms. Creditors may check liquidity before lending money. These decisions become useful only when accounts follow consistent accounting principles.
Q3. What Is Meant By Accounting Information?
Accounting information means financial data recorded, classified, summarised, and reported through books of account and financial statements.
It tells users about profit, loss, assets, liabilities, capital, and financial position. This information helps users make business and financial decisions.
Q4. Why Should Accounting Information Be Comparable?
Accounting information should be comparable because users need to judge performance across firms and time periods.
Inter-firm comparison shows how one business performs against another. Inter-period comparison shows how the same business performs across different years.
Q5. What Are Generally Accepted Accounting Principles?
Generally Accepted Accounting Principles, or GAAP, are the common rules used for recording and reporting business transactions.
GAAP brings uniformity in financial statements. It makes accounting information more acceptable to owners, investors, creditors, and other users.
GAAP Class 11 Accountancy Questions With Answers
GAAP is one of the most important ideas in Chapter 2. It explains why accountants cannot record transactions according to personal judgement alone.
These GAAP class 11 accountancy questions are useful for direct definitions and reasoning-based answers.
Q6. What Does The Term ‘Generally Accepted’ Mean In GAAP?
The term ‘generally accepted’ means accepted by most accounting professionals as a common rule or practice.
It does not mean that every rule is permanent. Accounting principles change with business needs, laws, and economic conditions.
Q7. Why Are GAAP Called Principles, Concepts, And Conventions?
GAAP are called principles, concepts, and conventions because they guide accounting practice in different ways.
Concepts are basic assumptions. Conventions are customs followed in accounting. Principles are accepted rules used for recording transactions.
Q8. Give One Example Of GAAP In Accounting.
Historical cost is an example of GAAP.
If machinery is bought for ₹5,00,000, it is recorded at ₹5,00,000 in the books. The accountant does not record it at market value unless rules allow it.
Q9. Are Accounting Principles Static In Nature?
Accounting principles are not static in nature.
They change with legal, social, and economic conditions. They also change when users need better financial information.
Accounting Principles Class 11 Important Questions
Accounting principles turn business events into proper accounting records. They decide which transactions should be recorded, when they should be recorded, and at what value.
These accounting principles class 11 questions should be answered with the rule first, then a business example.
Q10. What Is The Business Entity Concept?
Business entity concept states that the business and its owner are treated as separate entities.
If the owner brings ₹1,00,000 into the business, the business records it as capital. If the owner withdraws cash for personal use, it is treated as drawings.
Q11. Why Are Personal Expenses Of The Owner Not Treated As Business Expenses?
Personal expenses of the owner are not treated as business expenses because the owner and business are separate.
For example, the owner’s family shopping cannot reduce business profit. If paid from business cash, it is recorded as drawings.
Q12. What Is The Money Measurement Concept?
Money measurement concept states that only transactions measurable in money are recorded in books.
Purchase of goods, rent paid, salary due, and cash received are recorded. Employee honesty, staff skill, and brand reputation are not recorded because they cannot be measured in rupees.
Q13. State One Limitation Of Money Measurement Concept.
Money measurement concept ignores non-monetary factors that may affect business performance.
It also ignores changes in the value of money. A building bought years ago may appear at historical cost, even if prices have changed.
Q14. What Is The Going Concern Concept?
Going concern concept assumes that a business will continue for a long period.
This allows accountants to spread the cost of assets over their useful life. For example, a computer bought for ₹50,000 may be depreciated over several years.
Q15. Why Is Going Concern Concept Important For Assets?
Going concern concept is important because assets are used over many accounting periods.
If a business will continue, the full cost of an asset is not charged in one year. Only the used portion is charged as depreciation.
Q16. What Is The Accounting Period Concept?
Accounting period concept means financial statements are prepared after a fixed period.
Usually, businesses prepare accounts for one year. This helps users know profit, loss, assets, and liabilities at regular intervals.
Q17. Why Do Businesses Prepare Accounts Every Year?
Businesses prepare accounts every year because users need timely financial information.
Owners want to know profit. Banks want to know repayment capacity. Tax authorities need income details for tax purposes.
Basic Accounting Concepts Class 11 Questions With Answers
Basic accounting concepts help students understand the reason behind journal entries and financial statements. They form the base for later chapters such as recording transactions and preparation of financial statements.
These basic accounting concepts class 11 questions cover cost, dual aspect, revenue recognition, matching, and disclosure.
Q18. What Is The Cost Concept?
Cost concept states that assets are recorded at their purchase cost.
Purchase cost includes buying price, transport cost, installation cost, and any cost needed to make the asset ready for use.
Q19. A Machine Is Bought For ₹2,00,000. Transport Is ₹5,000 And Installation Is ₹10,000. At What Value Will It Be Recorded?
The machine will be recorded at ₹2,15,000.
Calculation:
Purchase price = ₹2,00,000
Transport = ₹5,000
Installation = ₹10,000
Total cost = ₹2,00,000 + ₹5,000 + ₹10,000 = ₹2,15,000
Final Answer: Machine will be recorded at ₹2,15,000.
Q20. What Is The Dual Aspect Concept?
Dual aspect concept states that every transaction has two effects.
For example, when cash is introduced as capital, cash increases and capital also increases. This concept supports the double entry system.
Q21. What Is The Accounting Equation?
The accounting equation is:
Assets = Liabilities + Capital
It means every asset of the business is financed either by the owner or by outsiders.
Q22. Show The Accounting Equation When A Proprietor Starts Business With ₹80,000 Cash.
The transaction increases cash and capital by the same amount.
Accounting Equation:
Assets = Liabilities + Capital
Cash ₹80,000 = ₹0 + Capital ₹80,000
Final Answer: Assets ₹80,000 = Liabilities ₹0 + Capital ₹80,000.
Q23. Show The Accounting Equation When Goods Worth ₹20,000 Are Purchased For Cash.
This transaction increases stock and decreases cash.
Accounting Equation before transaction:
Assets = Liabilities + Capital
Cash ₹80,000 = ₹0 + Capital ₹80,000
Effect after goods purchase:
Cash decreases by ₹20,000.
Stock increases by ₹20,000.
Final Answer: Total assets remain ₹80,000 because one asset increases and another asset decreases.
Q24. What Is The Revenue Recognition Concept?
Revenue recognition concept states that revenue is recorded when it is earned.
Credit sales are recorded when goods are sold, not when cash is received. Rent and interest are recorded for the period to which they belong.
Q25. Why Is A Customer Order Not Recorded As Sales?
A customer order is not recorded as sales because revenue has not been earned yet.
Sales are recorded when goods are sold or services are provided. A mere order does not create revenue.
Q26. What Is The Matching Concept?
Matching concept states that expenses of a period must be matched with revenues of the same period.
For example, salary for March must be recorded in March accounts, even if paid in April. This gives correct profit for the year.
Q27. Why Is Depreciation Charged Every Year?
Depreciation is charged every year because the asset helps earn revenue over many years.
The matching concept requires only the used portion of the asset to be charged against revenue of that year.

Matching Concept Class 11 And Related Concepts
Some accounting concepts work together. Matching, revenue recognition, accounting period, and accrual basis are closely connected.
These matching concept class 11 questions help students avoid common confusion in profit calculation.
Q28. How Are Matching Concept And Revenue Recognition Concept Related?
Revenue recognition decides when income is recorded. Matching concept decides which expenses relate to that income.
Together, they help calculate correct profit or loss for an accounting period.
Q29. Explain Matching Concept With An Example.
Matching concept means expenses should be recorded in the same period as related revenue.
Example: Goods costing ₹40,000 are sold for ₹60,000 in March. The cost of those goods must be matched with March sales to calculate correct profit.
Q30. Why Is Outstanding Salary Recorded In The Current Year?
Outstanding salary is recorded in the current year because employees have already provided services.
The expense belongs to the current accounting period. Payment date does not change the period of expense.
Q31. Why Is Prepaid Insurance Not Fully Treated As Expense?
Prepaid insurance is not fully treated as expense because part of it relates to a future period.
Only the insurance used during the current period is charged as expense. The remaining amount is treated as an asset.
Conservatism Concept Class 11 Important Questions
Conservatism protects financial statements from overstating profits and assets. It tells accountants to be careful when there is uncertainty.
These conservatism concept class 11 questions often appear as statement-based questions.
Q32. What Is Conservatism Concept?
Conservatism concept states that expected losses should be recorded, but expected profits should not be recorded until realised.
It is also called prudence. It prevents businesses from showing inflated profits.
Q33. Give Two Examples Of Conservatism Concept.
Two examples of conservatism concept are provision for doubtful debts and valuation of stock at cost or market value, whichever is lower.
These treatments protect the business from showing profits before they are certain.
Q34. Which Concept Is Based On “Do Not Anticipate Profits But Provide For All Losses”?
The conservatism concept is based on this statement.
It means accountants should record probable losses but ignore unrealised gains until they actually occur.
Q35. Why Should Unrealised Gains Not Be Recorded?
Unrealised gains should not be recorded because they are uncertain.
If profits are recorded before realisation, the business may distribute dividend out of capital. This weakens the financial position.
Accounting Standards Class 11 Important Questions
Accounting standards make financial statements more useful and comparable. They give clear rules for recognition, measurement, presentation, treatment, and disclosure.
These accounting standards class 11 questions are important for long answers.
Q36. What Are Accounting Standards?
Accounting standards are written policy documents that guide accounting treatment and disclosure.
They are issued by ICAI in India. They help bring uniformity in accounting policies and financial statements.
Q37. State The Main Objective Of Accounting Standards.
The main objective of accounting standards is to improve reliability and comparability of financial statements.
They reduce differences in accounting treatment. They also help users compare results across firms and accounting periods.
Q38. State Three Benefits Of Accounting Standards.
Accounting standards help eliminate variations in accounting treatment.
They require useful disclosures for investors, creditors, and the public. They also improve comparison between financial statements of different firms and the same firm over time.
Q39. State Three Limitations Of Accounting Standards.
Accounting standards may make accounting treatment less flexible.
They cannot override law. They may also make it difficult to choose between different valid accounting treatments.
Cash Basis And Accrual Basis Important Questions
The basis of accounting decides the timing of income and expense recording. This affects profit calculation directly.
Students should know cash basis and accrual basis with examples because both appear in short-answer and difference questions.
Q40. What Is Cash Basis Of Accounting?
Cash basis of accounting records transactions only when cash is received or paid.
For example, rent for December paid in January is recorded in January. Credit sales are recorded only when cash is collected.
Q41. What Is Accrual Basis Of Accounting?
Accrual basis of accounting records income and expenses when they arise.
Revenue is recorded when earned. Expenses are recorded when incurred, even if cash is received or paid later.
Q42. Why Is Accrual Basis Better For Profit Calculation?
Accrual basis is better because it matches revenue with related expenses.
It gives a more accurate picture of profit. It also follows the matching concept.
Q43. Differentiate Between Cash Basis And Accrual Basis.
Cash basis records cash movement. Accrual basis records the financial effect when income or expense arises.

GST Class 11 Accountancy Important Questions
GST connects accounting with real business taxation. Chapter 2 explains GST as a destination-based tax on goods and services.
These GST class 11 accountancy questions help students understand CGST, SGST, and IGST with examples.
Q48. What Is GST?
GST means Goods and Services Tax.
It is a destination-based tax on consumption of goods and services. The final consumer bears the tax burden.
Q49. What Are The Main Components Of GST?
The main components of GST are CGST, SGST, and IGST.
CGST is collected by the Central Government. SGST is collected by the State Government. IGST applies to inter-state supply.
Q50. When Are CGST And SGST Charged?
CGST and SGST are charged on intra-state transactions.
If goods are sold within the same state, both Centre and State collect tax. For example, sale within Punjab attracts CGST and SGST.
Q51. When Is IGST Charged?
IGST is charged on inter-state transactions.
If goods move from one state to another, IGST applies. For example, sale from Maharashtra to Gujarat attracts IGST.
Q52. Calculate GST On Intra-State Sale Of Goods Worth ₹10,000 At 18%.
Intra-state sale attracts CGST and SGST.
Given Data:
Sale value = ₹10,000
GST rate = 18%
CGST = 9%
SGST = 9%
Calculation:
CGST = ₹10,000 × 9 / 100 = ₹900
SGST = ₹10,000 × 9 / 100 = ₹900
Total GST = ₹900 + ₹900 = ₹1,800
Final Answer: CGST is ₹900, SGST is ₹900, and total GST is ₹1,800.
Q53. Calculate IGST On Inter-State Sale Of Goods Worth ₹25,000 At 18%.
Inter-state sale attracts IGST.
Given Data:
Sale value = ₹25,000
IGST rate = 18%
Calculation:
IGST = ₹25,000 × 18 / 100
IGST = ₹4,500
Final Answer: IGST is ₹4,500.
Case-Based Important Questions Class 11 Accountancy Chapter 2

Assets should be recorded at purchase cost. Market value cannot replace historical cost without proper accounting treatment.
Q56. A Firm Changes Its Depreciation Method Every Year To Show Higher Profit. Which Concept Is Violated?
The consistency concept is violated.
A firm should follow the same accounting method every year. Frequent changes reduce comparability and reliability.
Q57. A Firm Creates Provision For Doubtful Debts. Which Concept Applies?
The conservatism concept applies.
The firm expects some debtors may not pay. Possible losses should be provided in the books.
Q58. A Firm Receives An Order For Goods But Does Not Record It As Sales. Which Concept Applies?
The revenue recognition concept applies.
Revenue is recorded when goods are sold or services are provided. An order alone does not create sales revenue.
Q59. A Firm Records Salary Due But Not Paid At Year-End. Which Concept Applies?
The matching concept applies.
Salary belongs to the current accounting period. It must be recorded even if payment happens later.
Q60. A Firm Does Not Record Employee Skill In Books. Which Concept Applies?

Accounting concepts ensure similar transactions are recorded in a similar way.
- Reliable Financial Statements
They reduce personal judgement and improve trust in accounts.
- Better Comparison
They help compare one firm with another and one year with another.
- Correct Profit Calculation
Concepts like matching and revenue recognition help calculate accurate profit.
- Clear Financial Position
Concepts like cost and going concern guide asset valuation.
Q62. Explain The Matching Concept And Its Importance.
Matching concept states that expenses incurred in an accounting period should be matched with revenues of the same period.
It helps calculate correct profit or loss. Revenue alone cannot show performance unless related expenses are also recorded.
Importance of matching concept:
- Correct Profit
It prevents overstatement or understatement of profit.
- Proper Expense Recognition
Expenses are recorded in the period in which they help earn revenue.

Example:
If goods sold in March cost ₹30,000 and sales revenue is ₹50,000, both must be recorded in March accounts.
Q63. Explain The Dual Aspect Concept With Examples.
Dual aspect concept states that every business transaction has two effects.
This concept is the foundation of double entry system. It keeps the accounting equation balanced.
Accounting Equation:
Assets = Liabilities + Capital
Example 1:
Owner brings ₹1,00,000 cash into business.
Effect:
Cash increases by ₹1,00,000.
Capital increases by ₹1,00,000.
Equation:
Assets ₹1,00,000 = Liabilities ₹0 + Capital ₹1,00,000
Example 2:
Goods worth ₹20,000 are purchased for cash.
Effect:
Stock increases by ₹20,000.
Cash decreases by ₹20,000.
Total assets remain unchanged.
