Final answer:
Bank A has no excess reserves, Bank B can increase its loans by $40, and Bank C has excess reserves. option d is answer
Step-by-step explanation:
Bank A has actual reserves of $1,000, which is 10% of its demand deposits of $5,000. Therefore, Bank A has met its reserve requirement and does not have any excess reserves.
Bank B has actual reserves of $100, but its demand deposits are only $600. The reserve requirement for Bank B would be $60 (10% of $600), so Bank B does have excess reserves of $40 ($100 - $60).
Bank C has actual reserves of $10, which is 10% of its demand deposits of $100. Therefore, Bank C has met its reserve requirement and does not have any excess reserves.
Based on this information, the correct answer is Bank B can increase its loans by $40. option d is answer
