B Correct answer
Explanation

$\Rightarrow$   Process of loan repayment by installment payment is classified as $amortizing\,a\,loan.$

$\Rightarrow$   All repayments of interest-bearing debts by a series of payments, usually in size, made at equal intervals of time is called an amortization. Mortgages and many consumer loans are repaid by this method.
$\Rightarrow$  An amortized loan is a loan with scheduled periodic payments that consist of both principal and interest. An amortized loan payment pays the relevant interest expense for the period before any principal is paid and reduced. 
$\Rightarrow$   This is opposed to loans with interest-only payment features, balloon payment features and even negatively amortizing payment features.

Find the present value (in Rs) of a sequence of annual payments of Rs $10000$ each, the first being made at the end of $5^{th}$ year and the last being made at the end of $12^{th}$ year, if money is worth $6\%$.

D Correct answer
Explanation

Here, we have a deferred annuity of $8$ terms(n), deferred for $4$ terms.Each installment, A=Rs $10000$
Rate of interest, $r=$ $6\%$= $0.06$
m= $4$, $m + n=$ $12$
Using the formula, present value
$V = \dfrac{A}{r}$ $\times \dfrac{1}{(1+r)^m}$ - $\frac {1}{(1+r)^{m+n}}$
$V = \dfrac{10000}{0.06} \times [(1.06)^{-4}-(1.06)^{-12}]$$ =49187.38$

Find SI if, Amount =  $Rs \ 1120$ , Rate = $2\dfrac{2}{5}\%$ per year , Time = $5$ years 
  1. $1200$
  2. $201$
  3. $120$
  4. $134.4$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$ SI= prt$

$p$ is the principal amount on which interest is to be calculated
$r$ is the rate of interest at which the loan is taken
$t$ is the time period for which the simple interest is to be calculated
From the question we know that,
$p=Rs 1120, $ $r =2.4$ percent and $t=5$ years
$\Rightarrow SI = (1120)(2.4)(0.01)(5)= 134.4$

A sum of Rs $2500$ is invested at a rate of $5 \%$ per annum for a term of $5$ years. Find the simple interest received at the end of the term.

  1. $1250$
  2. $625$
  3. $1200$
  4. $1500$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$\Rightarrow$  Here, $P=Rs.2500,\, R=5\%,\, T=5\,years$.

$\Rightarrow$  $Simple\, Interest=\dfrac{P\times R\times T}{100}$
$\Rightarrow$  $\dfrac{2500 \times 5\times 5}{100}$
$\Rightarrow$  $25\times 25$
$\therefore$  $Simple\, Interest\, =Rs.625$

A $5-$year ordinary annuity has a present value of $\$1,000$.  If the interest rate is $8$ percent, the amount of each annuity payment is closest to which of the following? 

    1. $ $250.44$
    2. $ $231.91$
    3. $ $181.62$
    4. $ $184.08$
    5. $ $170.44$
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    $\Rightarrow$   We have, $V=\$1000\, r=8\%=0.08$ and $n=5$

    $\Rightarrow$  $V=\dfrac{A}{r}\times [1-(1+r)^{-n}]$
    $\Rightarrow$  $A=\dfrac{V\times r}{1-(1+r)^{-n}}$

    $\Rightarrow$  $A=\dfrac{1000\times 0.08}{1-(1.08)^{-5}}$

    $\therefore$     $A=\$250.44$

    1. $864$
    2. $800$
    3. $900$
    4. $820$
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    Each Installment = $\dfrac{P{\cdot}r}{100[1-{{ \frac{100}{100+r} }}^n]}$

    here $P = Rs1820$
    $r=0.2$
    $n=3$
    solving gives $Installment = 864Rs$

    Mr. Gupta has been accumulating a fund at $8\%$ effective, which will provide him with an annual income of Rs $30000$ for $15$ years, the first payment being paid on his $60^{th}$ birthday. If he wishes to reduce the number of payments to $10$, find how much annual income (in Rs) will he receive?

    1. $38268$
    2. $30268$
    3. $38208$
    4. $38068$
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    In first case, we have annuity due of $15$ terms.
    Its present value (as on Mr. Gupta's $60^{th}$ birthday),
    $v = \frac{A}{r} \times (1+r) \times [1-(1+r)^{-n}]$
    = $\frac{3000}{0.08} \times 1.08 \times [1-(1.08)^{-15}]$
    Now if only $10$ payments are to be received, we have annuity due of $10$ terms. If A is the amount of each annual installment,
    $\frac{A}{0.08} \times 1.08 \times [1-(1.08)^{-10}]$
    Thus,
    $\frac{A}{0.08} \times 1.08 \times [1-(1.08)^{-10}]$ = $\frac{3000}{0.08} \times 1.08 \times [1-(1.08)^{-15}]$
    A = $30000 \times \frac{[1-(1.08)^{-15}]}{[1-(1.08)^{-10}]}$
    A = $38268$

      C Correct answer
      Explanation

      $\Rightarrow$  Dollar amount of mortgage loan multiplied monthly payment of mortgage loan per dollar is used to calculate $monthly\,mortgage\,payment.$

      $\Rightarrow$  The most common mortgage terms are 15 years and 30 years. Interest rate Annual fixed interest rate for this mortgage. Monthly payment (PI) Monthly principal and interest payment (PI). 
      $\Rightarrow$  Monthly payment (PITI) Monthly payment including principal, interest, homeowners insurance and property taxes.

      Find the present value and amount of an ordinary annuity of 8 quarterly payments of Rs 500 each, the rate of interest being 8% p.a. compounded quarterly.

      1. $4375$
      2. $4275$
      3. $4175$
      4. $4475$
      Reveal answer Fill a bubble to check yourself
      B Correct answer
      Explanation

      $\Rightarrow$  Here, $A=Rs.500,\, n=8$ and $r=\dfrac{8}{100}\times \dfrac{1}{4}=0.02$

      $\Rightarrow$  $V=\dfrac{A}{r}\times [1-(1+r)^{-n}]$
      $\Rightarrow$  $V=\dfrac{500}{0.02}\times [1-(1.02)^{-8}]$
      $\Rightarrow$  Now, let $x=(1.02)^{-8}$
      $\Rightarrow$  $log\,x=-8\,log\,1.02=-8(0.0086)$
      $\Rightarrow$  $log\,x=-0.0688$
      $\Rightarrow$  $x=0.8535$
      $\Rightarrow$  $V=\dfrac{500}{0.02} \times [1-0.8535]=Rs.3662.50$
      $\Rightarrow$  Now, $M=\dfrac{A}{r}\times [(1+r)^n -1]$
      $\Rightarrow$  $\dfrac{500}{0.02}\times [(1.02)^8-1]$
      $\Rightarrow$  Let $x=(1.02)^8$
      $\Rightarrow$  $log\, x =8\, log\, (1.02)=0.0688$
      $\Rightarrow$  $x=1.171$
      $\therefore$   $M=\dfrac{500}{0.02}\times [1.171-1]=Rs.4275$
      $\therefore$    The present value of annuity is $Rs.3662.50$ and amount is $Rs.4275$
