Explanation / Answer

Effective interest rate:

= (1+D÷(1­-D))^(365÷n)-1

D is discount rate

n is Number of days after discount period

1)

= (1+1%÷(1­-1%))^(365÷15)-1

= 27.71%

2)

= (1+2%÷(1­-2%))^(365÷15)-1

= 63.49%

3)

= (1+1%÷(1­-1%))^(365÷35)-1

= 11.05%

4)

= (1+1%÷(1­-1%))^(365÷10)-1

= 44.32%
