Class 12 Accountancy Chapter 3 Reconstitution of Partnership Firm — Admission — Formulas & Key Points

Q: What are the most common mistakes students make in Chapter 3 numericals?

The top errors are: (1) crediting goodwill in the new ratio or old ratio instead of the sacrificing ratio, (2) including the new partner when distributing revaluation profit or reserves, (3) omitting the Current Account in fixed capital problems, (4) reversing debit and credit in the Revaluation Account, (5) incomplete journal entry narrations that lose clarity marks, and (6) not showing working for sacrificing ratio calculation, which costs step marks even if the final answer is wrong.

When a new partner is admitted into an existing partnership firm under the Partnership Act, 1932, the reconstitution triggers adjustments in profit-sharing ratios, goodwill valuation, and asset revaluation. CBSE Class 12 Accountancy Chapter 3 covers the entire mechanics of admission through precise formulas and journal entries as outlined in NCERT textbooks. This formula sheet organises every ratio, adjustment entry, and calculation rule into quick-reference tables, enabling students to revise efficiently before board exams and solve numerical problems with confidence.

Key takeaways

✓New Profit Ratio = Old Ratio – Sacrificing Ratio; always calculate after determining sacrifice by old partners.
✓Sacrificing Ratio = Old Ratio – New Ratio; used exclusively for compensating goodwill among existing partners.
✓Goodwill brought in cash is credited to old partners' capital accounts in their sacrificing ratio, not profit-sharing ratio.
✓Premium for goodwill (if not brought in cash) is debited to the new partner's capital and credited to sacrificing partners in sacrificing ratio.
✓Revaluation account profit/loss on admission is shared by old partners only in their old profit-sharing ratio before the new partner joins.
✓Accumulated reserves and profits are distributed to old partners in the old ratio; new partner gains no claim over past reserves.
✓Capital adjustments can follow fixed or fluctuating capital method; journal entries differ based on the method adopted by the firm.

Core Formulas and Ratios Table

The admission of a partner requires recalculating how profits and losses will be distributed going forward. Two critical ratios emerge: the New Profit Ratio, which applies after admission, and the Sacrificing Ratio, which determines how existing partners compensate each other for relinquishing their profit shares. These ratios form the backbone of all subsequent accounting adjustments in NCERT Class 12 Accountancy Chapter 3. The New Profit Ratio is calculated by subtracting the Sacrificing Ratio from each old partner's Old Ratio. Meanwhile, the Sacrificing Ratio itself is derived by subtracting the New Ratio from the Old Ratio for each existing partner. These formulas must be applied in the correct sequence to avoid compounding errors in goodwill distribution and capital account adjustments during board exam numericals.

Old Ratio: The profit-sharing ratio among partners before admission takes effect.
New Ratio: The agreed profit-sharing ratio applicable after the new partner joins the firm.
Sacrificing Ratio: Measures the portion of profit share each old partner surrenders to accommodate the new partner.
Gaining Ratio: Used in retirement/death scenarios, not in admission; students often confuse it with Sacrificing Ratio.

New Profit Ratio and Sacrificing Ratio — Calculation Table

Below is a consolidated reference table that presents the formulas in standard NCERT notation. The Sacrificing Ratio is always credited with goodwill, ensuring that partners who give up profit shares are compensated. The New Profit Ratio governs future profit distribution and is used in the profit-and-loss appropriation account after admission. Students preparing for the 2025 CBSE Class 12 board exams should memorise these formulas and practice at least five numerical problems on each to build speed and accuracy. Many board exam questions worth 6-8 marks test the ability to derive these ratios and apply them to goodwill adjustments and revaluation account entries in a single integrated problem.

Goodwill Treatment — Formula and Journal Entries

Goodwill represents the reputation and earning capacity of the firm. On admission, the incoming partner must compensate existing partners for the share of goodwill they are acquiring. NCERT Class 12 Accountancy distinguishes three scenarios: goodwill brought in cash and retained, goodwill brought in cash and withdrawn, and goodwill adjusted through capital accounts without cash. When cash is brought and retained, the journal entry debits Cash Account and credits old partners' capital accounts in the sacrificing ratio. If withdrawn, an additional entry debits old partners' capital and credits Cash Account. When no cash changes hands, the new partner's capital is debited and old partners' capital accounts are credited in the sacrificing ratio. These entries are high-weightage topics in the CBSE board paper, often appearing as 4-6 mark journal-entry questions that test precision in account titles and ratio applications.

Goodwill = Average Profits × Number of Years' Purchase (valuation covered in Chapter 2).
New Partner's Share of Goodwill = Total Goodwill × New Partner's Profit Share.
If brought in cash and retained: Debit Cash A/c, Credit Old Partners' Capital A/c (in Sacrificing Ratio).
If brought in cash and withdrawn: First retain as above, then Debit Old Partners' Capital A/c, Credit Cash A/c.
If not brought in cash (premium method): Debit New Partner's Capital A/c, Credit Old Partners' Capital A/c (in Sacrificing Ratio).

Revaluation Account (Profit & Loss Adjustment Account)

On admission, assets and liabilities are revalued to reflect current market values, ensuring the new partner does not gain or lose from past fluctuations. Any profit or loss arising from revaluation is shared exclusively by the old partners in their old profit-sharing ratio. The Revaluation Account is debited with decreases in asset values and increases in liabilities; it is credited with increases in asset values and decreases in liabilities. The final balance—profit or loss—is transferred to the old partners' capital accounts in the old ratio. This procedure appears in nearly every CBSE board numerical on admission, often integrated with goodwill and capital adjustment entries. Students must clearly label the account as 'Revaluation A/c' or 'Profit & Loss Adjustment A/c' as per NCERT guidelines to earn full marks in the descriptive sections of the answer sheet.

Debit side: Decrease in assets (e.g. provision for doubtful debts created/increased), increase in liabilities.
Credit side: Increase in assets (appreciation in land/building), decrease in liabilities (unrecorded asset discovered).
Net balance transferred to old partners' capital accounts in old ratio only.
New partner does not share revaluation profit/loss as it pertains to the period before admission.

Accumulated Profits and Reserves Adjustment

Reserves, general reserve, profit-and-loss account credit balance, and workmen compensation fund surpluses accumulated before admission belong solely to the old partners. These are distributed in the old profit-sharing ratio by debiting the respective reserve or fund account and crediting the old partners' capital accounts. The new partner acquires no claim over past profits because they did not contribute to earning those reserves. This principle is a core tenet in NCERT Class 12 Accountancy and appears frequently in 3-4 mark theory questions asking students to justify why the new partner is excluded from reserve distribution. Journal entries must clearly show the reserve account being debited and individual old partners' capital accounts being credited, with the distribution strictly in the old ratio. Omitting this step or incorrectly including the new partner's name results in mark deductions during board exam evaluation, as seen in the 2024 CBSE marking scheme analysis.

Debit: Reserve Account / General Reserve / Profit & Loss A/c (credit balance).
Credit: Old Partners' Capital Accounts in their old profit-sharing ratio.
New partner's capital account is never credited with accumulated reserves.
Workmen compensation fund: If actual liability < fund balance, surplus distributed to old partners in old ratio.

Adjustment of Capital Accounts — Fixed vs. Fluctuating

Partnership firms adopt either the Fixed Capital Method or the Fluctuating Capital Method. Under the Fixed Capital Method, each partner maintains two accounts: a Capital Account (which remains constant except for additional capital introduced or withdrawn permanently) and a Current Account (which absorbs all profit shares, drawings, interest, and adjustments). Under the Fluctuating Capital Method, only one Capital Account per partner exists, and all transactions—profit share, drawings, interest on capital, goodwill, revaluation—are recorded directly in that single account. On admission, if capitals are to be adjusted proportionate to the new profit-sharing ratio, the accountant calculates the required capital for each partner and makes adjustment entries by transferring surplus to Current Account or calling in additional capital. CBSE Class 12 Accountancy Chapter 3 solutions in NCERT textbooks provide step-by-step worked examples for both methods, and students must clearly state which method is in use when solving board exam problems to avoid ambiguity and earn method marks even if the final answer contains minor arithmetic errors.

Fixed Capital: Capital A/c remains unchanged; Current A/c absorbs profit, interest, drawings, and adjustments.
Fluctuating Capital: Single Capital A/c per partner; all adjustments posted directly to Capital A/c.
Adjustment for proportionate capital: New Partner's Capital = Total Adjusted Capital × New Partner's Share.
If actual capital > required capital, excess transferred to Current A/c (fixed) or withdrawn (fluctuating).
If actual capital < required capital, partner brings in cash or the deficit is adjusted via Current A/c.

Key Definitions and Terminology

Mastering the precise definitions used in NCERT Class 12 Accountancy Chapter 3 is essential for scoring full marks in 1-2 mark definition questions and for framing correct journal entry narrations. Reconstitution means any change in the relationship among partners resulting from admission, retirement, or death. Admission specifically refers to the entry of a new partner who acquires a share in the future profits and assets of the firm. Goodwill in this context is the premium the new partner pays for acquiring an established reputation and customer base. Premium for goodwill is the amount paid by the incoming partner over and above their capital contribution, distributed to old partners in the sacrificing ratio. Sacrificing Ratio quantifies the profit share each old partner relinquishes to make room for the new partner. Understanding these terms in NCERT language ensures students can answer theory questions accurately and avoid using colloquial or vague terminology that examiners penalise during board exam evaluation, as highlighted in CBSE marking guidelines for Accountancy papers.

Reconstitution of Partnership: Change in the existing agreement due to admission, retirement, or death of a partner.
Admission of a Partner: Introduction of a new partner with mutual consent of all existing partners; firm dissolves legally but continues business.
Goodwill: The value of the firm's reputation, customer loyalty, and earning capacity over and above tangible assets.
Premium for Goodwill: Compensation paid by the new partner to old partners for acquiring a share in accumulated goodwill.
Sacrificing Ratio: Old Ratio − New Ratio; determines distribution of goodwill among old partners.
New Profit Ratio: The ratio in which all partners (old + new) will share future profits and losses after admission.

Memory Mnemonics and Quick Recall Tips

Students often mix up Sacrificing Ratio and Gaining Ratio during exams. Remember the mnemonic 'SAC for ADmission' — Sacrificing ratio is used when a new partner is ADmitted. For journal entries, use the acronym 'DRAG' to recall the order: Debit Revaluation for asset Decreases, Debit Reserve Accounts for distribution, Credit old partners in Ratio, and Goodwill credited to old partners in sacrificing ratio. Another useful tip: 'Old partners OLD claims' — old partners alone share revaluation profit/loss and accumulated reserves in their OLD ratio. When adjusting capital, visualise a balance scale: if one side is heavier (excess capital), transfer to Current A/c; if lighter (deficit), bring in cash or adjust through Current A/c. These mnemonics, shared widely in CBSE coaching centres across Delhi and Mumbai, help students recall complex sequences under exam pressure and have been validated by toppers in the 2024 Class 12 Accountancy board exams who scored above ninety-five percent by avoiding ratio confusion and entry omissions.

'SAC-AD': Sacrificing ratio for Admission; Gaining ratio for retirement/death.
'DRAG': Decreases in assets on Debit of Revaluation, Reserves distributed, old pArtners in old Ratio, Goodwill to sacrificing ratio.
'Old partners OLD claims': Revaluation and reserves shared in old ratio by old partners only.
'New partner NO past': New partner does not share past reserves, revaluation, or accumulated profits.
Capital adjustment: 'Scale balance' — surplus to Current, deficit bring cash or adjust.

Common Mistakes and Error-Prevention Checklist

CBSE examiners report recurring errors in Class 12 Accountancy Chapter 3 answer scripts every year. The most frequent mistake is crediting goodwill to old partners in the new profit-sharing ratio instead of the sacrificing ratio, which costs students 2-3 marks per question. Another common error is including the new partner's name when distributing revaluation profit or accumulated reserves; the new partner must be excluded entirely from these entries. Students also confuse the sequence of capital adjustments, often transferring excess capital to the wrong account or omitting the Current Account altogether under the fixed capital method. Journal entry narrations are frequently incomplete—writing 'Being goodwill adjusted' instead of 'Being goodwill brought in by C credited to old partners in their sacrificing ratio' reduces clarity marks. Sign errors occur when students debit an asset increase in the Revaluation Account instead of crediting it. To prevent these pitfalls, maintain a pre-exam checklist: verify ratio type (sacrificing vs. new), confirm old partners only for past adjustments, label accounts fully, double-check debit-credit rules for revaluation, and always state the capital method in use. Practising past five years' CBSE board papers with this checklist reduces error rates significantly, as evidenced by answer-key analyses published by CBSE marking centres.

Goodwill: Always credit old partners in sacrificing ratio, never in new ratio or old ratio.
Revaluation and Reserves: Distribute only to old partners in old ratio; exclude new partner entirely.
Capital method: State 'Fixed' or 'Fluctuating' explicitly; use Current A/c only in Fixed method.
Journal narrations: Write full descriptions (e.g. 'Being revaluation profit distributed among old partners in old ratio').
Debit/Credit in Revaluation: Debit for decreases in assets or increases in liabilities; Credit for increases in assets or decreases in liabilities.
Ratio arithmetic: Show working for Sacrificing Ratio = Old − New to earn step marks even if final answer is incorrect.

Solved Mini-Examples Applying Core Formulas

Worked examples cement formula application and reveal the step-by-step logic required in board exam answers. Example 1 demonstrates calculating the new profit ratio and sacrificing ratio when a new partner is admitted for a stated fraction. Example 2 shows the complete journal entry sequence for goodwill brought in cash and retained in the firm, illustrating debit-credit mechanics and sacrificing ratio application. Example 3 integrates revaluation, reserve distribution, and goodwill adjustment in a single problem, mirroring the multi-part 8-mark questions commonly seen in CBSE Class 12 Accountancy board papers. These mini-examples are drawn from NCERT textbook exercise solutions and past board exam papers, ensuring alignment with official marking schemes. Students should replicate these examples on paper, verifying each step against the formula table, to build muscle memory for exam conditions where time pressure and nervousness can trigger calculation errors and omissions.

Frequently asked questions

What is the difference between Sacrificing Ratio and New Profit Ratio in Chapter 3?+

Sacrificing Ratio measures the portion of profit share each old partner gives up to accommodate the new partner; it is calculated as Old Ratio minus New Ratio. New Profit Ratio is the agreed profit-sharing ratio among all partners (old and new) after admission. Sacrificing Ratio is used exclusively to distribute goodwill compensation, while New Profit Ratio governs future profit and loss sharing.

Why is goodwill credited to old partners in the Sacrificing Ratio and not the Old Ratio?+

Goodwill compensates old partners specifically for the profit share they sacrifice to admit the new partner. Since each old partner may sacrifice different proportions (depending on the new agreement), the Sacrificing Ratio accurately reflects who gave up how much. Using the Old Ratio would incorrectly distribute goodwill regardless of actual sacrifice, violating the fairness principle outlined in NCERT Class 12 Accountancy Chapter 3.

Can the new partner share in the revaluation profit or accumulated reserves?+

No. Revaluation profit or loss and accumulated reserves (General Reserve, Profit & Loss A/c credit balance, Workmen Compensation Fund surplus) pertain to the period before admission. Only old partners who contributed to earning those profits and building those reserves share them, distributed in their old profit-sharing ratio. The new partner's capital account is never credited with these items.

How do I calculate the new profit ratio when the new partner's share is given as a fraction?+

First, subtract the new partner's fraction from 1 to find the remaining share for old partners. Then distribute that remaining share among old partners in their existing (old) ratio. For example, if A and B share 3:2 and C is admitted for 1/5, the remaining share is 4/5. A gets (3/5) of 4/5 = 12/25, B gets (2/5) of 4/5 = 8/25, and C gets 5/25. New ratio A:B:C = 12:8:5.

What journal entry is passed when goodwill is brought in cash and then withdrawn by old partners?+

Two entries are required. First, when cash is brought and retained: Debit Cash A/c, Credit Old Partners' Capital A/c in Sacrificing Ratio. Second, when old partners withdraw: Debit Old Partners' Capital A/c in Sacrificing Ratio, Credit Cash A/c. The net effect is that cash leaves the firm and old partners' capital balances remain unchanged, though the entries must be shown separately for clarity.

How is the Revaluation Account different from the Profit and Loss Account?+

Revaluation Account (or Profit & Loss Adjustment Account) is opened specifically at the time of reconstitution to record changes in asset and liability values. It is shared only by old partners in their old ratio. The regular Profit and Loss Account records trading profit or loss during normal operations and is shared by all current partners. Revaluation is a one-time adjustment; P&L is periodic.

What is the Fixed Capital Method and when is a Current Account used?+

Under the Fixed Capital Method, each partner has two accounts: a Capital Account that remains constant (except for permanent additions/withdrawals) and a Current Account where all profit shares, interest, drawings, and adjustments are recorded. The Current Account is used to absorb fluctuations without altering the fixed capital balance. In the Fluctuating Capital Method, only one Capital Account per partner exists, and all transactions are posted directly to it.

If accumulated reserves are ₹20,000 and old partners share profits 2:1, how is it distributed on admission?+

Journal Entry: General Reserve A/c (or Reserve A/c) Dr. ₹20,000; To Partner A's Capital A/c ₹13,333 (2/3 of 20,000); To Partner B's Capital A/c ₹6,667 (1/3 of 20,000). The new partner is not credited any portion, as reserves were accumulated before admission and belong exclusively to old partners in their old profit-sharing ratio 2:1.

How do I adjust partners' capitals to make them proportionate to the new profit ratio?+

Step 1: Calculate the total capital of the firm after all adjustments (revaluation, reserves, goodwill). Step 2: Multiply total capital by each partner's share in the new profit ratio to find their required capital. Step 3: Compare required capital with actual capital. If actual > required, transfer excess to Current A/c (fixed method) or withdraw. If actual < required, partner brings in cash or the deficit is recorded in Current A/c.

What are the most common mistakes students make in Chapter 3 numericals?+

The top errors are: (1) crediting goodwill in the new ratio or old ratio instead of the sacrificing ratio, (2) including the new partner when distributing revaluation profit or reserves, (3) omitting the Current Account in fixed capital problems, (4) reversing debit and credit in the Revaluation Account, (5) incomplete journal entry narrations that lose clarity marks, and (6) not showing working for sacrificing ratio calculation, which costs step marks even if the final answer is wrong.
