Question:

At what rate of interest will the present value of a perpetuity of Rs 300 payable at the end of each quarter be Rs 24000 ?

Options:

5% p.a

4%p.a

3%p.a

6%p.a

Correct Answer:

5% p.a

Explanation:

The correct answer is option (1) : 5% p.a

Let the rate of interest be r% per annum

then $i=\frac{r}{100}$

Given $R= ₹300$

$P=₹24000$

So, $i=\frac{R}{P}⇒\frac{r}{400}=\frac{300}{24000}$

$r= 5$% P.a
