Answer:
The summary as per the given query is summarized in the explanation section below..
Step-by-step explanation:
The given values are:
The nominal rate of return,
= 7%
i.e.,
= 0.07
Inflation,
= 4%
i.e.,
= 0.04
- Lengthy-term inflation would lessen the return on investment that lowers the net return as long-term investments are made.
- It can also aim to obtain a higher return that will comfortably exceed the rate of inflation and therefore is beneficial towards diminishing the average return.
Now,
The rate of return will be:
=
![((1+ nominal \ rate \ of \ return)/(1+Inflation)) -1](https://img.qammunity.org/2022/formulas/business/college/p5by83iycj7488jjcuzyxsjnuy6538l80b.png)
On substituting the values, we get
=
![((1+0.06)/(1+0.04) )-1](https://img.qammunity.org/2022/formulas/business/college/m7qwt7f4vvxpxhb7kb6utcmwksv4frfozr.png)
=
![((1.07)/(1.04) )-1](https://img.qammunity.org/2022/formulas/business/college/iccjug91x8rc2u2giides0twqbb6onpeh5.png)
=
![1.028846-1](https://img.qammunity.org/2022/formulas/business/college/6jtb3ssh5e89pi2t38hfes1ou9e3f6a8hv.png)
=
![2.8846 \ percent](https://img.qammunity.org/2022/formulas/business/college/vb107zmhd61yg4u67tmqar5bx84e6qg9z3.png)
Therefore it isn't able to measure the average return rate because the quantity of years for its expenditure.
