Answer:
6.80%
Step-by-step explanation:
The average nominal returns is the sum of the returns for 5 years divided by the number of returns considered( i.e 5, 5 returns for 5 years)
average nominal returns=(6%-13%+24%+18%+15%)/5
average nominal returns=10.00%
The Fisher's equation is shown thus:
(1 + i) = (1 + r) (1 + π)
i=nominal return=10.00%
r=average real return=the unknown
π=inflation rate=3%
(1+10.00%)=(1+r)*(1+3%)
1.10=(1+r)*1.03
1+1=1.10/1.03
r=(1.10/1.03)-1
r=6.80%
