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

A Trial Balance is a crucial accounting statement prepared at the end of an accounting period. Its primary purpose is to verify the arithmetical accuracy of the ledger accounts. It is compiled by listing the debit and credit balances of all the accounts from the ledger. The Trial Balance typically has two columns: one for debit balances and one for credit balances. All accounts with debit balances are listed in the debit column, and all accounts with credit balances are listed in the credit column. If the totals of both columns match, it indicates that the ledger accounts are arithmetically accurate. This statement serves as a summary of the ledger and is a vital step before preparing the final financial statements like the Profit and Loss Account and the Balance Sheet. It is usually prepared on a monthly or yearly basis.

Errors of principle occur when the recording of transactions violates fundamental accounting principles. These errors do not necessarily affect the agreement of the Trial Balance but lead to incorrect financial statements. Here are two examples:

1. Wages paid for construction of a building debited to Wages Account: When wages are paid for constructing a building, this cost should be treated as a capital expenditure and added to the cost of the building. Therefore, the 'Building Account' should be debited. However, if it is mistakenly debited to the 'Wages Account' (treating it as a revenue expenditure), it is an error of principle.
2. Amount spent on repair of machinery debited to Machinery Account: Expenses incurred on routine repairs of machinery are revenue expenditures and should be debited to the 'Repairs Account'. If, instead, the amount is debited to the 'Machinery Account', it incorrectly capitalizes a revenue expense, which is an error of principle.

Errors of commission arise due to mistakes made during the recording, posting, balancing, or carrying forward of amounts. These errors can be made by any person involved in the accounting process. Here are two examples:

1. Goods purchased worth Rs 20,000 on credit are recorded in the Purchases Book as Rs 10,000: In this case, the amount of the transaction has been recorded incorrectly in the book of original entry (Purchases Book). The correct amount should have been Rs 20,000, but it was entered as Rs 10,000. This is an error in recording the amount.
2. Total of Sales Book is carried forward as Rs 5,000 instead of Rs 500: This error occurs when the total of a page in a book of accounts is incorrectly carried forward to the next page or to the next accounting period. Here, the total was wrongly carried forward as Rs 5,000 instead of the correct amount of Rs 500, leading to an imbalance in the accounts.

There are three primary methods for preparing a Trial Balance:

1. Total Method: In this method, the total of the debit side and the total of the credit side of each ledger account are transferred to the debit and credit columns, respectively, of the Trial Balance.
2. Balance Method: This is the most common method. Here, only the net balance (either debit or credit) of each ledger account is transferred to the respective columns of the Trial Balance.
3. Total and Balance Method: This method combines the previous two. Both the total debits and credits, as well as the net balances of each account, are shown in the Trial Balance. This method provides more detailed information but is less frequently used.
