Question:

If the present value of a perpetuity of ₹800 payable at the end of every six months be ₹20,000, then rate of interest is :

Options:

4% per annum

12% per annum

10% per annum

8% per annum

Correct Answer:

8% per annum

Explanation:

The correct answer is Option (4) → 8% per annum

The present value of a perpetuity,

$PV=\frac{A}{r}$

$20,000=\frac{800}{r}$

$r=\frac{800}{20,000}=4\%$

Annual Rate = $4\%×=8\%$
