Answer:
The correct answer is $50 billion and 4.
Step-by-step explanation:
According to the scenario, the given data are as follows:
Total deposits = $1,000 Billions
Reserve = 20% of total deposit = $200 billion
If reserve requirement change to 25%, then
Reserve = 25% of total deposit = $250 billion
Change in reserve = $250 billion - $200 billion = $50 billion
So, deficiency of reserve = $50 billion
We can calculate the monetary multiplier by using following formula:
Monetary multiplier = 1 ÷ Reserve ratio = 1 ÷ 25%
= 4
