On question 17.4 of the BPP revision kit, why does D have no effect on the trial balance? One might have not recorded part of the transaction in the cash book, but couldn’t you have recorded the other part of the transaction in the Receivables Journal when we receive the money that could have been applied to a balance?
However, a receipt of cash should be a debit in the cash book. If they have not recorded it in the cash book then the debits will be too low. The question asks which of the errors could make the debits too high.
