Answer:
4.65%
Step-by-step explanation:
Data provided in the question:
Amount borrowed = $18,000
Discount Interest rate = 4% = 0.04
Required compensating balance = 10%
Now,
Effective loan rate on Discount Loan with compensating balance is given as
⇒ [ ( Interest rate ) ÷ (1- interest %-Compensating balance%) ] × 100%
⇒ [ 4% ÷ ( 1 - 4% - 10%) ] × 100%
⇒ [ 0.04 ÷ ( 1 - 0.04 - 0.10 ) ] × 100%
⇒ [ 0.04 ÷ 0.86 ] × 100%
⇒ 4.65%
