Introduction to Accounting — Account STD 11 Commerce — Question

From the balancing of these accounts we can ascertain as to how much amount is owing from each individual customer and how much amount is owed to each individual creditor. If a personal account shows a debit balance, it indicates the amount owing from him. On the contrary, if a personal account shows a credit balance, it indicates the amount owing to him.In case the total of the debit side is in excess of the credit side, the difference between the two is inserted on the credit side of the account in order to make their totals equal. The words ‘By Balance c/d’, i.e., balance carried down are written against the amount of the difference. In the next accounting period, the balance is brought down on the debit side by writing the words ‘To Balance b/d'.
