Question: If a person invests $1000 at a simple interest rate of 5% per annum for 3 years, what will be the total amount at the end?

Options:

Correct Answer: $1150

Solution:

Simple Interest = Principal * Rate * Time = 1000 * 5/100 * 3 = 150. Total Amount = Principal + Interest = 1000 + 150 = 1150.

If a person invests $1000 at a simple interest rate of 5% per annum for 3 years, what will be the total amount at the end?

Step 1: Identify the principal amount (the initial investment). In this case, it is $1000.
Step 2: Identify the interest rate. Here, it is 5% per annum.
Step 3: Identify the time period for the investment. In this case, it is 3 years.
Step 4: Calculate the simple interest using the formula: Simple Interest = Principal * Rate * Time.
Step 5: Substitute the values into the formula: Simple Interest = 1000 * (5/100) * 3.
Step 6: Calculate the simple interest: 1000 * 0.05 * 3 = 150.
Step 7: Calculate the total amount at the end of the investment period by adding the principal and the interest: Total Amount = Principal + Interest.
Step 8: Substitute the values: Total Amount = 1000 + 150.
Step 9: Calculate the total amount: 1000 + 150 = 1150.
