Answer:
Added to Cash Book Balance in Bank Reconciliation Statement
Explanation:
Bank Reconciliation Statement BRS is made to correct for the mismatch between bank balance as per cash book & bank balance as per pas book.
If account has been credited (added) with $30 for interest earned, discovered later i.e not recorded in cash book : The amount has been added in passbook , but not in cashbook.
So, to match the difference : Interest earned but not recorded = $30 will be added to 'Favourable Debit balance as per cash book' , to achieve 'Favourable Credit balance as per pass book' in the BRS.
