Explanation / Answer

1) Monetary base = C + R

The monetary base (B) is money held by the public in currency and by banks as reserves R

CR = C/D

The currency-deposit ratio (cr) is the amount of currency people hold as a fraction of their demand deposits

So, H = C + R

R = 10% of deposits = 0.10D

So, C = H-R

= C = H-0.10D

Now, CR = C/D

= 0.25 = H-0.10D/D

= 0.25D = 1000 - 0/10D

So, 0.35D = 1000

D = $2,857.14

So, this is not more than $3,000

2) Loan amount is remaining balace after reducing the reserves from the deposits

So, C = H-R

R = 0.25D

C = H-0.25D

CR = C/D

0.40 = 1000 - 0.25D/D

= 0.65D = 1000

D = $1,538.46

So, loans = 1,538.46 - 25% reserves

= Loans = $1,153.85

This is not more than $1,500

3. This calculation is same as question 1.

D = $2,857.14

Reserves = 10%D

= $285.714 (2,857.14 * 10%)

This is more than $250 but less than $300

4. This is same as question 2.

D = $1,538.46

Reserves = 25%D

= $384.615 (1538.46*25%)

This is more than $225
