Find the principal which will amount to Rs. 4,000 in 4 years at 6.25% Per annum.

बेरीज

उत्तर

Given:

  • Final amount (A) = ₹4,000,
  • Time (T) = 4 years,
  • Rate of interest (R) = 6.25% per annum.

Formula for Simple Interest:

`A = P (1+(R.T)/100)`,

where

  • A = Final amount,
  • P = Principal.

Rearranging to find P:

`P=A/(1+(R.T)/100)`

`P=4000/(1+(6.25·4)/100)`

`P = 4000/1.25`

P = 3200.
