Q. Given that simple interest on a certain sum of money is 4016.254016.25 bucks at 9%9\% per annum in 55 years. Find the sum of money.
  1. Use Simple Interest Formula: To find the principal sum of money, we need to use the formula for simple interest: \newlineSimple Interest (SI) = Principal (PP) * Rate (RR) * Time (TT) / 100100\newlineWe are given:\newlineSimple Interest (SI) = 4016.254016.25 bucks\newlineRate (RR) = 99% per annum\newlineTime (TT) = 55 years\newlineWe need to solve for Principal (PP).
  2. Rearrange Formula for Principal: Rearrange the formula to solve for Principal PP:P=SIR×T/100P = \frac{SI}{R \times T / 100}Now plug in the given values:P=4016.259×5/100P = \frac{4016.25}{9 \times 5 / 100}
  3. Calculate Denominator: Calculate the denominator first: 9×5/100=45/100=0.459 \times 5 / 100 = 45 / 100 = 0.45
  4. Divide Simple Interest: Now divide the Simple Interest by the calculated value: \newlineP=4016.250.45P = \frac{4016.25}{0.45}
  5. Find Principal: Perform the division to find the principal: P=4016.250.45=8925P = \frac{4016.25}{0.45} = 8925
