Answer 2

Petty cash book is just like the cash book. The amounts received by the petty cashier from the main cashier are entered on the debit side of the petty cash book and payments on the credit side of the petty cash book.

Every small payment is entered twice on the credit side - one in the total payments column and second in one of the analytical amount column.

The periodic total of each column is posted to the expenses accounts concerned , while the total of payments column serves to find out the balance of cash with the petty cashier.
