It seems you have provided a set of multiple-choice questions regarding interest rates and investment growth, but I'm missing some context or detail that would allow me to accurately determine the actual interest rate and the value of the investment after 10 years.
To help you effectively, I need a little more information:
- What is the principal amount? (It seems you have mentioned 300, which might refer to the invested amount.)
- What is the type of interest used? (Is it simple interest or compound interest?)
- If it’s compound interest, what is the compounding frequency? (Annually, semi-annually, quarterly, etc.)
- Any other relevant details or parameters?
Once I have that, I can assist you in calculating the actual interest rate and the future value of the investment based on the duration of 10 years.
