A perpetuity pays Rs. 50 annually. If the interest rate is 8%, what is its present value?
  • a)
    Rs. 400   
  • b)
    Rs. 625   
  • c)
    Rs. 500   
  • d)
    Rs. 6250
Correct answer is option 'C'. Can you explain this answer?

Understanding Perpetuity
A perpetuity is a financial instrument that pays a constant amount indefinitely. In this case, the perpetuity pays Rs. 50 annually.
Present Value Formula
To find the present value (PV) of a perpetuity, you can use the formula:
PV = C / r
Where:
- C = Cash flow per period (Rs. 50)
- r = Discount rate (interest rate as a decimal, so 8% becomes 0.08)
Calculation Steps
1. Identify the Cash Flow (C):
- C = Rs. 50
2. Identify the Interest Rate (r):
- r = 8% = 0.08
3. Apply the Formula:
- PV = 50 / 0.08
4. Perform the Calculation:
- PV = 50 / 0.08
- PV = 625
Final Answer
The present value of the perpetuity is Rs. 625, which corresponds to option 'b'.
Conclusion
Understanding the calculation of present value for perpetuities is crucial in finance, as it helps in making informed investment decisions. In this example, the Rs. 625 present value indicates the worth today of receiving Rs. 50 annually indefinitely at an 8% interest rate.

If the present value of a perpetuity is Rs. 3000 and the annual cash flow is Rs. 150, what is the discount rate?
  • a)
    5%   
  • b)
    10%   
  • c)
    8%   
  • d)
    15%
Correct answer is option 'B'. Can you explain this answer?

We use the perpetuity formula PV = CF / r, where PV is the present value, CF is the cash flow, and r is the discount rate. Rearranging the formula, we get r = CF / PV. Substituting the given values, we get r = 150 / 3000 = 0.05, or 5%, expressed as a percentage.
