Explanation
In the circular flow of income and spending, savings, taxes and imports are called leakages or withdrawals since they result in a decrease in the volume of the income flow, whereas investment spending and government expenditure and exports are all injections into the circular flow since they result to an increase in the volume of the income flow.

plus new reserves R 800 R 1
(New deposit less the reserve ratio of 20%:
Total excess reserves 600 R1 000 – 200 = 800)
less loan to Mary R 600 R 1
New excess reserves 000
Question 14
Suppose the bank receives a cheque deposit of R300 and its excess reserves increase by R255, the required reserve ratio must be … .
1) 5%
2) 15% The correct alternative is [2]. 3) 25%
4) 65%
5) 38%
Explanation
The reserve ratio (rr) can be calculated as follows:
(300−25)
300
x 100
= 0, 15 x 100 = 15%

At an aggregate level, the transactions demand for money is a function of national income.
