Question

Write a note on one-sided errors and two sided errors.

Answer 1

• Rectification of one-sided errors before preparing trial balance:

1. When a one-sided error is detected before preparing the trial balance, no journal entry is required to be passed in the books.
2. In such cases, the error can be rectified by giving an explanatory note in the account affected as to whether the concerned account is to be debited or credited.
3. Example: Sales book is undercast by ₹ 100.
4. In this case, the sales book is undercast by ₹ 100.
5. The total of sales book is posted to the credit side of the sales account in the ledger.
6. The under casting has resulted in an under-crediting of sales accounts by ₹ 100.
7. This is an error of commission.
8. The error is only in the sales account. There is short credit in the sales account by ₹ 100. Hence, it is rectified by crediting sales account by ₹ 100.

• Rectification of two-sided errors before preparing the trial balance:

When a two-sided error is detected before preparing the trial balance, it must be rectified by passing a rectifying journal entry in the journal proper after analyzing the error.

Example: Goods sold to Anand for ₹ 1,000 on credit was not entered in the sales book. The entry will be

Date	Particulars	I.F.	Debit ₹	Credit ₹
	Anand A/c    Dr		1,000
	To Sales A/c			1,000
	(Being the sale of goods to anand not entered in sales book, now rextified)

Method of deriving the rectifying entries

No	Wrong Entry	Correct Entry	₹	₹	Rectifying Entry	₹	₹
	Nil (Complete Omission)	Anand A/c  Dr. To sales A/c	1,000	1,000	Anand A/c  Dr.    To sales A/c	1,000	1,000
