Respuesta :
Invested amount in a government bond = $50.
Total returned amount after 1 year =$54.
We need to find the amount of interest earned first.
Amount of intrest earned in a year = Total returned amount after 1 year - Invested amount in the government bond.
Therefore, Amount of intrest earned in a year = $54 - $50.
= $4.
Therefore, earned interest is $4 in an year.
Now, we need to find the intrest rate.
We know the formula,
[tex]Interest \ rate=\frac{Earned \ Interest}{Invested \ Money} \times 100[/tex]
Plugging values in above formula, we get
Rate of interest = [tex]\frac{4}{50} \times100[/tex]
Dividing 100 by 50, we get 2.
[tex]\frac{4}{50} \times100= 4\times2=8[/tex]
Therefore, Rate of Interest (ROI) = 8% per year.
