Answer
10 years
Explanation
We know the simple interest formula is \( I = \frac{P \times R \times T}{100} \). Given \( P = 450 \), \( R = 6 \), \( I = 270 \). Therefore, \( 270 = \frac{450 \times 6 \times T}{100} \) which simplifies to \( 270 = 27 \times T \), so \( T = 10 \) years.
Key Points
- > Basic simple interest formula is \( I = \frac{PRT}{100} \)
- > Use \( T = \frac{100 \times I}{PR} \) to calculate time
- > Simple interest grows linearly with time
Additional Information
- Simple interest is calculated only on the principal amount.
- It is simpler and generally lower than compound interest.
- The total amount at the end of the period is \( A = P + I \).
