Answer: 1.67
Step-by-step explanation:
From the question, we are informed that the currency drain ratio is 0.5 of deposits and the banks' reserve ratio is 0.4.
The money multiplier is calculated as:
(1 + the currency drain ratio)/( the reserve ratio + the currency drain ratio)
= (1 + 0.5)/(0.5 + 0.4)
= 1.5/0.9
= 1.67
Therefore, the money multiplier will be 1.67.
