Trial Balance and Rectification of Errors — NCERT Solutions

Errors of Commission:

Errors of commission are errors that arise due to wrong recording of a transaction in the books of accounts. These include:

• Wrong totalling (overcasting or undercasting) of subsidiary books
• Wrong balancing of ledger accounts
• Posting to the correct account but with wrong amount
• Posting to the correct account but on the wrong side
• Posting to the wrong account

Characteristics:

• Some errors of commission affect the trial balance (one-sided errors), while others do not (two-sided errors).
• They arise due to carelessness or negligence.

Example 1: Credit sales to Ramesh ₹5,000 credited to his account (posting on wrong side)

Error: Ramesh's account was credited with ₹5,000 instead of being debited.

Wrong Entry:
$$\text{Sales A/c Dr. } 5{,}000 \quad \text{To Ramesh's A/c } 5{,}000$$
(Actually: Sales A/c is correctly credited in Sales Book; only Ramesh's A/c is wrongly credited instead of debited.)

Correct Effect:
$$\text{Ramesh's A/c Dr. } 5{,}000 \quad \text{To Sales A/c } 5{,}000$$

Rectification Entry:
$$\text{Ramesh's A/c Dr. } 10{,}000 \quad \text{To Suspense A/c } 10{,}000$$
(Ramesh's account needs to be debited by ₹10,000 — ₹5,000 to reverse the wrong credit and ₹5,000 for the correct debit.)

Example 2: Overcasting of Sales Book by ₹1,000

Error: The total of the Sales Book was added as ₹1,000 more than the correct total, causing Sales A/c to be credited with ₹1,000 extra.

Rectification Entry:
$$\text{Sales A/c Dr. } 1{,}000 \quad \text{To Suspense A/c } 1{,}000$$
(Sales A/c is debited to reduce the excess credit; Suspense A/c is credited.)

Types of Errors in Recording Business Transactions:

1. Errors of Commission:
These arise due to wrong recording, wrong posting, wrong totalling, or wrong balancing.

• Sub-types: Error of recording (wrong amount in books of original entry), Error of posting (wrong amount, wrong side, or wrong account in ledger), Error of casting (wrong totalling of subsidiary books), Error of carrying forward, Error of balancing.
• Example: Credit sales to Mohan ₹7,000 posted to his account as ₹700.

2. Errors of Omission:
These arise when a transaction is either completely or partially omitted from the books.

• Complete Omission: Transaction not recorded at all — does not affect trial balance.
• Partial Omission: Transaction recorded in one account but not posted to the other — affects trial balance.
• Example: Credit purchases from Rohan ₹9,000 not recorded at all.

3. Errors of Principle:
These arise when a transaction is recorded in violation of accounting principles, especially wrong classification between capital and revenue.

• They do not affect the agreement of the trial balance.
• Example: Furniture purchased debited to Purchases Account.

4. Compensating Errors:
These are two or more errors that cancel out each other's effect on the trial balance. The trial balance agrees despite the errors.

• Example: Sales Book overcast by ₹500 and Purchases Book also overcast by ₹500 — the excess debit in Purchases cancels the excess credit in Sales.

Summary Table:

Given Information:

• A credit purchase of a pendrive for ₹3,500 was correctly recorded in the journal.
• Correct Journal Entry should be: Pendrive (Office Equipment) A/c Dr. ₹3,500 / To Creditors A/c ₹3,500
• Wrong Posting done: Office Equipment A/c Dr. ₹3,500 AND Creditors A/c Dr. ₹3,500 (both debited instead of one debit and one credit).
• Office Equipment balance shown in trial balance = ₹15,600.

Analysis of the Error:

(a) Office Equipment Account:

The Office Equipment account was correctly debited with ₹3,500 (as it should be). Therefore, the balance of ₹15,600 is correctly stated. There is no misstatement in this account.

(b) Creditors Account:

The Creditors account should have been credited with ₹3,500 (liability increases), but instead it was debited with ₹3,500. This means:

• The credit side is short by ₹3,500 (missing credit)
• The debit side has an extra ₹3,500 (wrong debit)
• Net effect: Creditors balance is overstated on the debit side by ₹7,000 (or understated as a credit balance by ₹7,000).

The Creditors account balance is understated (as a credit/liability) by ₹7,000.

(c) Debit Column Total of Trial Balance:

The Creditors account was debited with ₹3,500 (wrong). This extra debit of ₹3,500 appears in the debit column. Therefore, the debit column total is overstated by ₹3,500.

(d) Credit Column Total of Trial Balance:

The Creditors account should have been credited with ₹3,500 but was not. Therefore, the credit column total is understated by ₹3,500.

(e) Total of Credit Column:

Debit column total (before correction) = ₹2,40,000

Since the debit column is overstated by ₹3,500 and the credit column is understated by ₹3,500:

$$\text{Credit column total} = ₹2,40,000 - ₹3,500 - ₹3,500 = ₹2,33,000$$

Alternatively: The credit column total = ₹2,40,000 − ₹7,000 = ₹2,33,000

(The debit total exceeds the credit total by ₹7,000, so credit total = ₹2,40,000 − ₹7,000 = ₹2,33,000.)

These are errors of complete omission. Since neither side was recorded, both accounts are affected equally — these are two-sided errors and do not affect the trial balance. Rectification is done by passing the correct journal entry.

Journal Entries for Rectification:

(i) Credit sales to Mohan ₹7,000 not recorded:

(ii) Credit purchases from Rohan ₹9,000 not recorded:

(iii) Goods returned to Rakesh ₹4,000 not recorded:

(iv) Goods returned from Mahesh ₹1,000 not recorded:

These are errors of commission (wrong amount recorded in the books of original entry). Both sides are affected by the same wrong amount — two-sided errors. Rectification is done by recording the difference.

Journal Entries for Rectification:

(i) Credit sales to Mohan recorded as ₹700 instead of ₹7,000 (short by ₹6,300):

(ii) Credit purchases from Rohan recorded as ₹900 instead of ₹9,000 (short by ₹8,100):

(iii) Goods returned to Rakesh recorded as ₹400 instead of ₹4,000 (short by ₹3,600):

(iv) Goods returned from Mahesh recorded as ₹100 instead of ₹1,000 (short by ₹900):

These are errors of commission (excess amount recorded). Both sides are affected — two-sided errors. Rectification is done by recording the excess amount in reverse.

Journal Entries for Rectification:

(i) Credit sales to Mohan recorded as ₹7,200 instead of ₹7,000 (excess by ₹200):

(ii) Credit purchases from Rohan recorded as ₹9,900 instead of ₹9,000 (excess by ₹900):

(iii) Goods returned to Rakesh recorded as ₹4,040 instead of ₹4,000 (excess by ₹40):

(iv) Goods returned from Mahesh recorded as ₹1,600 instead of ₹1,000 (excess by ₹600):

Journal Entries for Rectification:

(a) Salary paid ₹5,000 debited to employee's personal account instead of Salary Account:

This is an error of principle/commission. Salary A/c should have been debited.

(b) Rent paid ₹4,000 posted to landlord's personal account instead of Rent Account:

This is an error of commission. Rent A/c should have been debited.

(c) Goods withdrawn by proprietor ₹1,000 debited to Sundry Expenses Account instead of Drawings Account:

This is an error of commission/principle.

(d) Cash received from Kohli ₹2,000 posted to Kapur's account instead of Kohli's account:

This is an error of commission (wrong personal account credited).

(e) Cash paid to Babu ₹1,500 posted to Sabu's account instead of Babu's account:

This is an error of commission (wrong personal account debited).

These are errors of commission (wrong book used). Both sides are wrongly recorded — two-sided errors. Rectification requires reversing the wrong entry and recording the correct entry.

Journal Entries for Rectification:

(a) Credit sales to Mohan ₹7,000 recorded in Purchases Book:

Wrong entry: Purchases A/c Dr. 7,000 / To Mohan's A/c 7,000
Correct entry: Mohan's A/c Dr. 7,000 / To Sales A/c 7,000

(b) Credit purchases from Rohan ₹9,000 recorded in Sales Book:

Wrong entry: Rohan's A/c Dr. 9,000 / To Sales A/c 9,000
Correct entry: Purchases A/c Dr. 9,000 / To Rohan's A/c 9,000

(c) Goods returned to Rakesh ₹4,000 recorded in Sales Return Book:

Wrong entry: Sales Return A/c Dr. 4,000 / To Rakesh's A/c 4,000
Correct entry: Rakesh's A/c Dr. 4,000 / To Purchases Return A/c 4,000

(d) Goods returned from Mahesh ₹1,000 recorded in Purchases Return Book:

Wrong entry: Mahesh's A/c Dr. 1,000 / To Purchases Return A/c 1,000
Correct entry: Sales Return A/c Dr. 1,000 / To Mahesh's A/c 1,000

(e) Goods returned from Nahesh ₹2,000 recorded in Purchases Book:

Wrong entry: Purchases A/c Dr. 2,000 / To Nahesh's A/c 2,000
Correct entry: Sales Return A/c Dr. 2,000 / To Nahesh's A/c 2,000

Concept: Overcasting means the total of the book was added as more than the correct total. The total of subsidiary books is posted to the respective nominal accounts. Overcasting affects only the nominal account (not individual personal accounts) — one-sided error requiring Suspense Account.

Journal Entries for Rectification:

(a) Sales Book overcast by ₹700:

Sales A/c has been credited with ₹700 extra.

(b) Purchases Book overcast by ₹500:

Purchases A/c has been debited with ₹500 extra.

(c) Sales Return Book overcast by ₹300:

Sales Return A/c has been debited with ₹300 extra.

(d) Purchase Return Book overcast by ₹200:

Purchases Return A/c has been credited with ₹200 extra.

Concept: Undercasting means the total of the book was added as less than the correct total. The respective nominal account was posted with a lesser amount — one-sided error requiring Suspense Account.

Journal Entries for Rectification:

(a) Sales Book undercast by ₹300:

Sales A/c has been credited with ₹300 less.

(b) Purchases Book undercast by ₹400:

Purchases A/c has been debited with ₹400 less.

(c) Return Inwards (Sales Return) Book undercast by ₹200:

Sales Return A/c has been debited with ₹200 less.

(d) Return Outwards (Purchases Return) Book undercast by ₹100:

Purchases Return A/c has been credited with ₹100 less.

Concept: 'Not posted' means the entry was recorded in the subsidiary book/cash book but not posted to the respective ledger account. This is a one-sided error (partial omission) affecting only one account. Suspense Account is used.

Analysis of each error:

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹2,000 (excess credit)

(The credit side of Suspense A/c exceeds the debit side by ₹2,000, meaning the original trial balance had excess credit of ₹2,000.)

Concept: Wrong amount posted to the correct account — one-sided error. The difference between correct and wrong amount needs to be adjusted through Suspense Account.

Analysis:

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹5,800 (excess debit)

These are errors of commission (posting to wrong account). Both sides are affected equally — two-sided errors. No Suspense Account needed.

Journal Entries for Rectification:

(a) Credit sales to Mohan ₹7,000 posted to Karan instead of Mohan:

Karan's A/c was debited instead of Mohan's A/c.

(b) Credit purchases from Rohan ₹9,000 posted to Gobind instead of Rohan:

Gobind's A/c was credited instead of Rohan's A/c.

(c) Goods returned to Rakesh ₹4,000 posted to Naresh instead of Rakesh:

Naresh's A/c was debited instead of Rakesh's A/c.

(d) Goods returned from Mahesh ₹1,000 posted to Manish instead of Mahesh:

Manish's A/c was credited instead of Mahesh's A/c.

(e) Cash sales ₹2,000 posted to Commission Account instead of Sales Account:

Commission A/c was credited instead of Sales A/c.

(a) Credit sales to Mohan ₹7,000 posted to credit of his account (wrong side):

• Correct: Mohan's A/c Dr. 7,000
• Wrong: Mohan's A/c Cr. 7,000
• Difference: Mohan's A/c needs Dr. 14,000 (₹7,000 to reverse wrong credit + ₹7,000 for correct debit)
• Effect on TB: Debit side short by ₹14,000 → Suspense A/c Dr. 14,000

(e) Cash sales ₹2,000 posted to debit of Sales A/c as ₹5,000:

• Correct: Sales A/c Cr. 2,000
• Wrong: Sales A/c Dr. 5,000
• Need: Sales A/c Cr. 7,000 (₹5,000 to reverse wrong debit + ₹2,000 for correct credit)
• Effect on TB: Credit side short by ₹7,000 → Suspense A/c Cr. 7,000

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹14,800 (excess debit)

Concept: Since personal accounts are correctly posted, only the nominal/real accounts are affected (one-sided errors).

Analysis:

(a) Credit sales to Mohan recorded in Purchase Book; Mohan's A/c correctly debited:

• Mohan's A/c: Correctly Dr. 7,000 ✓
• Purchases A/c: Wrongly Dr. 7,000 (should be Sales A/c Cr. 7,000)
• Rectification: Dr. Purchases A/c reversed → Cr. Purchases A/c 7,000; Cr. Sales A/c 7,000; Dr. Suspense A/c 14,000
• Wait — Mohan's A/c is correctly debited. The wrong effect is: Purchases A/c Dr. 7,000 (instead of Sales A/c Cr. 7,000). So two nominal accounts are wrong.
• Rectification: Dr. Suspense A/c 14,000; Cr. Purchases A/c 7,000; Cr. Sales A/c 7,000
• TB effect: Debit excess by ₹14,000 (Purchases wrongly Dr. + Sales missing Cr.)

(b) Credit purchases from Rohan recorded in Sales Book; Rohan's A/c correctly credited:

• Rohan's A/c: Correctly Cr. 9,000 ✓
• Sales A/c: Wrongly Cr. 9,000 (should be Purchases A/c Dr. 9,000)
• Rectification: Dr. Sales A/c 9,000; Dr. Purchases A/c 9,000; Cr. Suspense A/c 18,000
• TB effect: Credit excess by ₹18,000 (Sales wrongly Cr. + Purchases missing Dr.)

(c) Goods returned to Rakesh recorded in Sales Return Book; Rakesh's A/c correctly debited:

• Rakesh's A/c: Correctly Dr. 4,000 ✓
• Sales Return A/c: Wrongly Dr. 4,000 (should be Purchases Return A/c Cr. 4,000)
• Rectification: Dr. Suspense A/c 8,000; Cr. Sales Return A/c 4,000; Cr. Purchases Return A/c 4,000
• TB effect: Debit excess by ₹8,000

(d) Goods returned from Mahesh recorded through Purchases Return Book; Mahesh's A/c correctly credited:

• Mahesh's A/c: Correctly Cr. 1,000 ✓
• Purchases Return A/c: Wrongly Cr. 1,000 (should be Sales Return A/c Dr. 1,000)
• Rectification: Dr. Purchases Return A/c 1,000; Dr. Sales Return A/c 1,000; Cr. Suspense A/c 2,000
• TB effect: Credit excess by ₹2,000

(e) Goods returned to Naresh recorded through Purchases Book; Naresh's A/c correctly debited:

• Naresh's A/c: Correctly Dr. 2,000 ✓
• Purchases A/c: Wrongly Dr. 2,000 (should be Purchases Return A/c Cr. 2,000)
• Rectification: Dr. Suspense A/c 4,000; Cr. Purchases A/c 2,000; Cr. Purchases Return A/c 2,000
• TB effect: Debit excess by ₹4,000

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹6,000 (excess debit)

These are errors of principle (wrong classification between capital and revenue). They are two-sided errors and do not affect the trial balance. No Suspense Account needed.

Journal Entries for Rectification:

(a) Furniture purchased ₹10,000 debited to Purchases Account instead of Furniture Account:

(b) Machinery purchased on credit from Raman ₹20,000 recorded through Purchases Book:

Wrong: Purchases A/c Dr. 20,000 / To Raman's A/c 20,000
Correct: Machinery A/c Dr. 20,000 / To Raman's A/c 20,000

(c) Repairs on machinery ₹1,400 debited to Machinery Account instead of Repairs Account:

(d) Repairs on overhauling of secondhand machinery ₹2,000 debited to Repairs Account instead of Machinery Account:

(Overhauling of secondhand machinery before use is capital expenditure — should be added to Machinery A/c.)

(e) Sale of old machinery at book value ₹3,000 credited to Sales Account instead of Machinery Account:

Analysis of each error (both wrong amount AND wrong account):

(a) Furniture ₹10,000 debited to Purchases A/c as ₹4,000:

• Wrong: Purchases A/c Dr. 4,000 (wrong account, wrong amount)
• Correct: Furniture A/c Dr. 10,000
• Rectification: Dr. Furniture A/c 10,000; Cr. Purchases A/c 4,000; Cr. Suspense A/c 6,000
• TB effect: Credit short by ₹6,000 (debit excess)

(b) Machinery ₹20,000 from Raman recorded in Purchases Book as ₹6,000:

• Wrong: Purchases A/c Dr. 6,000 / Raman's A/c Cr. 6,000
• Correct: Machinery A/c Dr. 20,000 / Raman's A/c Cr. 20,000
• Rectification: Dr. Machinery A/c 20,000; Cr. Purchases A/c 6,000; Cr. Raman's A/c 14,000; Cr. Suspense A/c 0 — wait:
• Raman's A/c was credited with ₹6,000 (wrong amount) instead of ₹20,000. So Raman's A/c needs additional credit of ₹14,000.
• Rectification: Dr. Machinery A/c 20,000; Cr. Purchases A/c 6,000; Cr. Raman's A/c 14,000
• This is a two-sided error (both accounts wrong) — no Suspense needed for this part. But wait — Purchases A/c Dr. 6,000 vs Machinery A/c Dr. 20,000: debit side short by ₹14,000 → Suspense A/c Dr. 14,000? No — Raman's A/c credit is also short by ₹14,000. Both sides are short by ₹14,000 — two-sided error for the amount difference. The account name change (Purchases to Machinery) is also two-sided. So overall two-sided — no Suspense.
• Rectification: Dr. Machinery A/c 20,000; Cr. Purchases A/c 6,000; Cr. Raman's A/c 14,000

(c) Repairs on machinery ₹1,400 debited to Machinery A/c as ₹2,400:

• Wrong: Machinery A/c Dr. 2,400 (wrong account, wrong amount)
• Correct: Repairs A/c Dr. 1,400
• Rectification: Dr. Repairs A/c 1,400; Cr. Machinery A/c 2,400; Dr. Suspense A/c 1,000
• TB effect: Debit short by ₹1,000 (2,400 − 1,400)

(d) Overhauling charges ₹2,000 debited to Repairs A/c as ₹200:

• Wrong: Repairs A/c Dr. 200 (wrong account, wrong amount)
• Correct: Machinery A/c Dr. 2,000
• Rectification: Dr. Machinery A/c 2,000; Cr. Repairs A/c 200; Cr. Suspense A/c 1,800
• TB effect: Credit short by ₹1,800 (debit excess)

(e) Sale of old machinery ₹3,000 credited to Sales A/c as ₹5,000:

• Wrong: Sales A/c Cr. 5,000 (wrong account, wrong amount)
• Correct: Machinery A/c Cr. 3,000
• Rectification: Dr. Sales A/c 5,000; Cr. Machinery A/c 3,000; Cr. Suspense A/c 2,000
• TB effect: Credit short by ₹2,000 (debit excess)

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹8,800 (excess credit)

Analysis:

(a) Depreciation on machinery ₹4,000 not posted:
'Not posted' — the journal entry was passed (Dr. Depreciation A/c, Cr. Machinery A/c) but neither account was posted. This is a complete omission of posting — two-sided error.

(b) Bad debts written off ₹5,000 not posted:
Complete omission of posting — two-sided error.

(c) Discount allowed ₹100 not posted (entire entry not posted):
The cash receipt was recorded in cash book (Cash A/c Dr., Discount A/c Dr., Debtor's A/c Cr.). 'Not posted' means none of the ledger accounts were posted — two-sided error.

Note: Cash A/c is part of the cash book itself and is automatically posted. The discount and debtor entries need to be posted.

(d) Discount allowed ₹100 not posted to Discount Account (only Discount A/c not posted):
Partial omission — one-sided error. Debtor's A/c was correctly credited; only Discount A/c was not debited.

(e) Bill receivable ₹2,000 received from debtor not posted:
The entry in the Bills Receivable Book: Bills Receivable A/c Dr. / To Debtor's A/c. 'Not posted' — complete omission — two-sided error.

These are errors of commission (wrong amount posted). Both sides are affected by the same wrong amount — two-sided errors. No Suspense Account needed.

Journal Entries for Rectification:

(a) Depreciation on machinery posted as ₹400 instead of ₹4,000 (short by ₹3,600):

(b) Bad debts posted as ₹6,000 instead of ₹5,000 (excess by ₹1,000):

(c) Discount allowed posted as ₹60 instead of ₹100 (short by ₹40):

(d) Goods withdrawn by proprietor posted as ₹300 instead of ₹800 (short by ₹500):

Correct entry: Drawings A/c Dr. / To Purchases A/c

(e) Bill receivable posted as ₹3,000 instead of ₹2,000 (excess by ₹1,000):

Concept: 'Not posted to [specific account]' means only one account was not posted — one-sided error. The other account was correctly posted.

Analysis:

Journal Entries for Rectification:

Suspense Account:

Difference in Trial Balance = ₹1,900 (excess credit)

(The credit side of Suspense A/c exceeds the debit side by ₹1,900, meaning the original trial balance had excess credit of ₹1,900.)

Given: Trial balance shows excess credit of ₹6,000. Suspense A/c is debited with ₹6,000 (to balance the trial balance).

Analysis of each error:

(a) Cash received from Ravish ₹8,000 posted to his account as ₹6,000:

• Ravish's A/c should be credited with ₹8,000 but was credited with only ₹6,000 (short by ₹2,000).
• One-sided error: Ravish's A/c needs additional credit of ₹2,000.
• Rectification: Dr. Suspense A/c 2,000; Cr. Ravish's A/c 2,000

(b) Returns Inwards Book overcast by ₹1,000:

• Sales Return A/c was debited with ₹1,000 extra.
• One-sided error: Cr. Sales Return A/c 1,000.
• Rectification: Dr. Suspense A/c 1,000; Cr. Sales Return A/c 1,000

(c) Total of Sales Book ₹10,000 not posted to Sales Account:

• Correct: Sales Return (Returns Inwards) A/c Dr. 1,200
• Wrong: Returns Outwards (Purchases Return) A/c Dr. 1,200 (or Cr. — depends on interpretation)
• Actually: The total of Returns Inwards Book is posted as a debit to Returns Inwards A/c. Here it was posted to Returns Outwards A/c. If posted as debit to Returns Outwards A/c: wrong account debited.
• More likely: Returns Outwards A/c was credited with ₹1,200 (wrong side, wrong account) — this is a two-sided error affecting two nominal accounts.

Analysis of each error:

(a) Credit sales to Manas ₹16,000 recorded in Purchases Book as ₹10,000; posted to debit of Manas as ₹1,000:

• Correct: Manas's A/c Dr. 16,000 / Sales A/c Cr. 16,000
• Wrong: Purchases A/c Dr. 10,000 (from Purchases Book total) / Manas's A/c Dr. 1,000 (wrong side, wrong amount)
• Rectification:
• Manas's A/c: Should be Dr. 16,000; Was Dr. 1,000 → needs Dr. 15,000 more
• Sales A/c: Should be Cr. 16,000; Was not credited → needs Cr. 16,000
• Purchases A/c: Should not be Dr.; Was Dr. 10,000 → needs Cr. 10,000
• Net: Dr. Manas's A/c 15,000; Dr. Suspense A/c 11,000; Cr. Sales A/c 16,000; Cr. Purchases A/c 10,000
• Check: Dr. 15,000 + 11,000 = 26,000; Cr. 16,000 + 10,000 = 26,000 ✓
• TB effect: Debit excess = 10,000 (Purchases wrong Dr.) + 1,000 (Manas wrong Dr.) − 16,000 (Sales missing Cr.) = −5,000 → Credit excess by ₹5,000? Let me recalculate.
• Wrong debits: Purchases Dr. 10,000 + Manas Dr. 1,000 = 11,000; Wrong credits: 0; Missing debits: Manas Dr. 16,000 − 1,000 = 15,000 needed; Missing credits: Sales Cr. 16,000; Purchases Cr. 10,000 needed.
• Suspense effect: Debit side of TB has 10,000 (Purchases) + 1,000 (Manas) = 11,000 extra/wrong; Credit side missing 16,000 (Sales) but Purchases Dr. 10,000 is extra. Net: Debit excess = 11,000; Credit short = 16,000 + 10,000 = 26,000? No.
• Let me think simply: Suspense A/c entry = Dr. Manas 15,000 + Dr. Suspense 11,000 = Cr. Sales 16,000 + Cr. Purchases 10,000. Suspense is Dr. 11,000 → TB had credit excess of ₹11,000 from this error.
