CBSE Class 11 Accountancy: Chapter 6 - Trial Balance and Rectification of Errors NCERT Solutions

Solution: A Trial Balance is a statement prepared to verify the arithmetical accuracy of the transactions that have been recorded in the journal, subsequently posted into the ledger, and then balanced in the individual ledger accounts. It essentially summarizes the debit and credit balances of all ledger accounts at a specific point in time. The balances considered include those of personal, real, and nominal accounts. While often prepared at the end of an accounting year, it can be prepared at any chosen interval (monthly, quarterly, half-yearly, or annually) as needed. Its primary function is to facilitate the preparation of financial statements like the Income Statement and Balance Sheet.

Solution: Errors of principle occur when accounting transactions are recorded in violation of fundamental accounting principles. These errors do not necessarily affect the agreement of the trial balance because the correct type of account might be debited or credited, but the wrong account within that category is used, or a capital expenditure is treated as revenue, or vice versa.

Here are two examples:

1. Wages paid for installation of new machinery debited to wages account: When new machinery is purchased and installed, the cost incurred, including installation charges, is a capital expenditure and should be debited to the Machinery Account. However, if this amount is debited to the Wages Account (which is a revenue expenditure), it is an error of principle.
2. Amount spent on repair of building debited to building account: Expenses incurred on routine repairs of a building are revenue expenditures and should be debited to the Repairs Account. If, instead, the amount is debited to the Building Account (a capital asset), it is an error of principle.

Solution: Errors of commission arise due to mistakes made during the recording, posting, balancing, or casting of subsidiary books or ledger accounts. These errors can affect the accuracy of the trial balance, especially if they are not self-correcting.

Here are two examples:

1. Cash received from a creditor worth Rs.5,000 is recorded in the cash book as Rs.500: In this case, the amount of the transaction has been recorded incorrectly in the primary book (cash book). The correct amount should be Rs.5,000, but it was entered as Rs.500, leading to an error in the accounting records.
2. Amount received from Arun Rs.2,000, is wrongly posted in Tarun's account: When cash is received from Arun, Arun's account should be credited. If, due to a mistake, Tarun's account is credited instead, this is an error of wrong posting. The transaction is correctly identified but posted to the incorrect ledger account.

Solution: A trial balance can be prepared using three primary methods:

1. Totals Method: In this method, the total of the debit side and the total of the credit side of each ledger account are calculated. These totals are then separately entered into the debit and credit columns of the trial balance. The sum of the debit totals should equal the sum of the credit totals.
2. Balances Method: This is the most commonly used method. Here, the closing balance (debit or credit) of each ledger account is determined. These balances are then listed in their respective debit or credit columns in the trial balance. The total of the debit balances should equal the total of the credit balances. This method is preferred because the balances are directly used for preparing the financial statements.
3. Totals-cum-Balances Method: This method combines the Totals Method and the Balances Method. It includes four columns: two for the totals of debit and credit sides of each account, and two for the debit and credit balances of each account. While it provides more information, it is more time-consuming and less frequently used in practice.

Solution: When the trial balance does not agree, an accountant follows a systematic approach to locate the errors:

1. Recast the totals: First, re-add the debit and credit columns of the trial balance to ensure there are no errors in the final summation.
2. Compare with ledger: Check each account listed in the trial balance against its corresponding account in the ledger to ensure the correct amount has been transferred and no account has been omitted or incorrectly included.
3. Compare with previous year's trial balance: Compare the current year's trial balance with the previous year's to identify any new accounts added, accounts that have been deleted, or significant unexplained changes in amounts.
4. Re-check ledger balances: Verify the accuracy of the balances calculated for each individual account in the ledger.
5. Re-check postings: Ensure that all entries from the books of original entry (like the journal or cash book) have been correctly posted to the respective ledger accounts.
6. Check casting of subsidiary books: If the difference in the trial balance is a round figure like `1, `10, `100, or `1000, it suggests a possible error in the casting (totaling) of the subsidiary books (e.g., sales book, purchase book).
7. Check for half-difference error: If the difference is an even number, divide it by 2. There's a possibility that an amount equal to half the difference was posted to the wrong side of a ledger account, or a posting was completely omitted.
8. Check for transposition error: If the difference is divisible by 9 (e.g., `18, `27, `36), it might indicate a transposition error, where digits in a number have been swapped (e.g., writing `25 instead of `52).
9. Transfer to Suspense Account: If, after all these checks, the errors cannot be located, the difference is temporarily transferred to a 'Suspense Account' to enable the preparation of financial statements. Any one-sided errors discovered later are rectified through this account.

Solution: A suspense account is a temporary ledger account used to hold the difference between the total debit and total credit columns of a trial balance when they do not match. It is created to allow the preparation of financial statements without delay, pending the discovery and correction of the errors causing the imbalance.

It is not always necessary that a suspense account will balance off immediately after the rectification of all detected errors. If the debit column of the trial balance falls short of the credit column, the difference is debited to the suspense account. Conversely, if the credit column falls short, the difference is credited to the suspense account.

If, after rectifying all the errors that could be identified, a balance still remains in the suspense account, it indicates that there are undetected errors. This remaining balance must be carried forward to the next accounting period. It will continue to be part of the trial balance in the subsequent period until the remaining errors are found and rectified, at which point the suspense account will finally be closed.
