The Future amount of annuity, $(M)$, can be found by

  1. $ M=\dfrac{A}{r} \times \left[(1+r)^{n}+1\right] $

  2. $ M=\dfrac{r}{A} \times \left[(1+r)^{n}-1\right] $

  3. $ M=\dfrac{A}{r} \times \left[(1+r)^{n}-1\right] $

  4. $ M=\dfrac{r}{A} \times \left[(1+r)^{n}+1\right] $


Correct Option: C
Explanation:

The future amount of annuity (M) can be founded by the formula

$M=\dfrac { A }{ r } \times \left[ { \left( 1+r \right)  }^{ n }-1 \right] $
Where $A$ is amount and $r$ is rate and $n$ is duration

Find the amount of an annuity of Rs. 400 per quarter payable for 6 years at 8% p.a.
[Given : $(1.02)^{24} = 1.608$]-

  1. Rs. 11,260

  2. Rs. 12,160

  3. Rs. 13,200

  4. None.


Correct Option: B
Explanation:

Formula for calculating the amount of an annuity,


$F=R \dfrac{\left ( 1+\dfrac{r}{m} \right )^{m \times n} -1}{\dfrac{r}{m}}$

$F=400 \dfrac{\left ( 1+\dfrac{8/100}{4} \right )^{4 \times 6} -1}{\dfrac{8/100}{4}}$

$F=400 \dfrac{\left ( 1+\dfrac{8}{100} \times \dfrac{1}{4} \right )^{24} -1}{\dfrac{8}{100} \times \dfrac{1}{4} }$

$F=400 \dfrac{(1.02)^{24} -1}{\dfrac{1}{50} }$

$F = 12,160$


Find the least number of years for which an annuity of Rs. 1,000 must run in order that its amount exceed Rs. 16,000 at 5% p.a. compounded monthly.
[Given : Log 18 = 1.2553, log 105 = 2.8212]

  1. 12 years

  2. 11 years

  3. 13 years

  4. None.


Correct Option: C
Explanation:
$F=R \dfrac{\left ( 1+\dfrac{r}{m} \right )^{m \times n} -1}{\dfrac{r}{m}}$

$16000=1000 \dfrac{\left ( 1+\dfrac{5}{100} \right )^n -1}{\dfrac{5}{100}}$

$16=1 \dfrac{\left ( 1+\dfrac{5}{100}  \right )^n -1}{\dfrac{5}{100}  }$

$0.8=(1.05)^n-1$

$1.8=(1.05)^n$

Applying log on both sides, we get,

$\log 1.8 = n \log 1.05$

$\Rightarrow n=13$

Least number of years = $13$ years
