Suppose the legal reserve ratio is 25%. If a person deposits $200 cash into his savings account, the maxmium possible change inA bank loans is an increase of $800
B bank reserves is an increase of $200
C M1 is a decrease of $50
D M2 is an increase of $800

If a $100 deposit of newly- printed money into a bank results in a $400 increase in the total deposit of the banking system, we can conclude that
A the banking multiplier of the above deposit creation is 4
B the legal reserve ratio is 0.25
C the money supply increase by $500
D there is no cash leakage

求econ高手賜教

Q1

Legal reserve ratio = 25%
Max. banking multiplier = 1/25% = 4x

After deposit creation:
R 200; D 800;
L 600;

M1: -200
M2: max. possible change is -200 in cash + 800 in deposit = +600

A is not correct. Max. possible change in bank loans is an increase of 600.

Q2:
Reserve + 100 results in Deposit + $400, so answer is A.
