Answer:
b. $50,000 and $250,000.
Explanation:
The computation is shown below:
The required reserve is
= Check-able-deposit liabilities × reserve ratio
= $500,000 × 20%
= $100,000
The excess reserves is
= Actual reserves - required reserves
= $150,000 - $100,000
= $50,000
And, the amount that increase the loan is
= Excess reserves ÷ reserve ratio
= $50,000 ÷ 20%
= $250,000
