Requirements: |
a.Information provided:
Present value= 500
Future value= $1,948
Time= 12 years
The interest rate is calculated by entering the below in a financial calculator:
PV= -500
FV= 1,948
N= 12
Press the CPT key and I/Y to compute the interest rate.
The value obtained is 12.14.
Therefore, the interest rate is 12.14%.
b. Information provided:
Present value= $300
Future value= $422.10
Time= 7 years
The interest rate is calculated by entering the below in a financial calculator:
PV= -300
FV= 422.10
N= 7
Press the CPT key and I/Y to compute the interest rate.
The value obtained is 4.9989
Therefore, the interest rate is 4.9989% 5%.
c. Information provided:
Present value= 50
Future value= $280.20
Time= 20 years
The interest rate is calculated by entering the below in a financial calculator:
PV= -50
FV= 280.20
N= 20
Press the CPT key and I/Y to compute the interest rate.
The value obtained is 8.9996.
Therefore, the interest rate is 8.9996% 9%.
d. Information provided:
Present value= 200
Future value= $497.60
Time= 5 years
The interest rate is calculated by entering the below in a financial calculator:
PV= -200
FV= 497.60
N= 5
Press the CPT key and I/Y to compute the interest rate.
The value obtained is 19.9969
Therefore, the interest rate is 19.9969% 20%.
In case of any query, kindly comment on the solution.
