Answer:
$5,660.
Step-by-step explanation:
The adjusted cash balance = Cash balance per company books on April 30 - Deposits in transit + Outstanding checks - Bank charge + Note receivable and interest - NSF check = $6,245 - $1,360 + $680 - $75 + $710 - $540 = $5,660.
Therefore, the adjusted cash balance per the books on April 30 is $5,660.
