Which column of journal book is filled up at the time of posting and not at the time of making journal entry?

Ledger Folio

The correct answer is option 4- Ledger Folio.

In the  journal book, transactions are recorded in the chronological order, as and when they take place. It has 5 columns.

1. The first column in a journal is Date on which the transaction took place.
2. In the Particulars column, the account title to be debited is written on the first line beginning from the left hand corner and the word ‘Dr.’ is written at the end of the column. The account title to be credited is written on the second line leaving sufficient margin on the left side with a prefix ‘To’. Below the account titles, brief description of the transaction is given which is called Narration. Having written the Narration a line is drawn in the Particulars column, which indicates the end of recording the specific journal entry.
3. The column relating to Ledger Folio records the page number of the ledger book on which relevant account is appears. This column is filled up at the time of posting and not at the time of making journal entry.
4. The Debit amount column records the amount against the account to be debited and similarly the Credit Amount column records the amount against the account to be credited.
