Understanding Simple Interest
Simple interest is calculated using the formula:
Interest = Principal × Rate × Time
Where:
- Principal is the initial sum of money.
- Rate is the interest rate (in decimal).
- Time is the duration the money is invested or borrowed for (in years).
Given parameters
- Rate = 10% per annum = 0.10
- Interest = 0.125 times the Principal
This means:
Interest = 0.125 × Principal
Setting up the equation
Using the formula for simple interest:
0.125 × Principal = Principal × 0.10 × Time
To simplify, divide both sides by Principal (assuming Principal is not zero):
0.125 = 0.10 × Time
Calculating Time
Now, we can solve for Time:
Time = 0.125 / 0.10
Time = 1.25 years
Conclusion
The time required for the simple interest to be 0.125 times the principal at a rate of 10% per annum is:
  • 1.25 years


This result indicates that if you invest or borrow a certain sum at 10% interest per annum, it will take 1.25 years for the interest to amount to 12.5% of the principal amount. Understanding this concept is essential for effective financial planning and investment strategies.
