Answer #1

a)
PV = 8000
FV = 10000
Nper = 8 * 3 = 24
PMT = 0

Nominal interest rate can be calculated by using the following excel formula:
=RATE(nper,pmt,pv,fv)
=RATE(24,0,-8000,10000)*3
= 2.80%

Nominal interest rate = 2.80%

b)
PV = 8000
FV = 10000
Nper = 8 * 12 = 96
PMT = 0

Nominal discount rate can be calculated by using the following excel formula:
=RATE(nper,pmt,pv,fv)
=RATE(96,0,-8000,10000)*12
= 2.79%

c)
PV = 8000
FV = 10000
Nper = 8
PMT = 0

Annual effective rate can be calculated by using the following excel formula:
=RATE(nper,pmt,pv,fv)
=RATE(8,0,-8000,10000)
= 2.83%
