Answer:
Purchase of 300
Step-by-step explanation:
Given,
Money Supply is 2,500
Bank's deposit ratio is 0.20
Bank reserve is 200
Currency held by public is 500
Increase in the money supply is 3,000
Bank Deposit (BD) = Bank reserve / Bank's deposit ratio
= 200 / 0.20
= 1,000
Money Supply = Bank Deposit + Currency held by public
= 1,000 + 500
= 1,500
Purchase of 300
Then New BD = 500 / 0.20
= 2,500
New Money supply = 2,500 + 500
= 3,000
So, in order to increase the money supply to 3,000, should conduct the open market purchase of 300 bonds.
