In how many years will the simple interest on 450 rupees be 270 rupees at an annual interest rate of 6%?

English বাংলা

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 \( A = P + I \).
