Answer:
d. The present value of perpetuity varies directly with the annual repayments.
Explanation:
A perpetuity is a security or bond which pays a fixed amount of cash flow at a fixed interval forever. So the amount it pays stays the same and it keeps paying for ever. The formula to find the present value of a perpetuity is
Cash flow of perpetuity/Interest Rate
So if the annual payment is 100 and the interest rate is 5% the present value of the annuity is
100/0.05=2,000
If we keep the interest rate the same at 5% and increase the cash flow by 100 to 200 the new present value of the perpetuity is
200/0.05=4,000
This proves that the present value of a perpetuity varies directly with the annual repayments or cash flow of perpetuity.
