The company offers a heater whose cost price is Rs. $9400$ at a monthly E.M.I for $24$ months. The interest charged is $6\%$. What is the monthly EMI to be paid by the customer?

  1. Rs. $340$
  2. Rs. $512$
  3. Rs. $439$
  4. Rs. $604$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$\Rightarrow$   We know, $EMI=\dfrac{Cost\, price+Interest}{Months}$


$\Rightarrow$   $T=24\,months=2\,years,\, R=6\%\,$ and $P=Rs.9400$.


$\Rightarrow$   $Interest = \dfrac{P\times R\times T}{100}=\dfrac{9400\times 6\times 2}{100}$

$\Rightarrow$   $Interest = Rs.1128.$


$\Rightarrow$   $EMI=\dfrac{9400+1128}{24}=Rs.438.66\approx Rs.439.$

  2. $17082$
  3. $16390$
  4. $16770$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$\Rightarrow$  Selling price of mobile phone is $Rs.15,600.$

$\Rightarrow$  Initial payment = $25\%\,\, of Rs.15,600.$
$\Rightarrow$  Initial payment = $\dfrac{25}{100}\times 15600=Rs.3900.$
$\Rightarrow$  Loan amount = Selling price - Initial payment.
$\Rightarrow$  Loan amount = $Rs.15,600-Rs.3,900=Rs.11,700.$

$\Rightarrow$  $Interest=\dfrac{11700\times 10\times 1}{100}=Rs.1170.$

$\Rightarrow$  Processing fee = $2\%\,\,of\,Rs.15600.$
$\Rightarrow$  Processing fee = $\dfrac{2}{100}\times 15600=Rs.312.$
$\Rightarrow$  Total amount paid = Selling price + Interest + Processing fee.
$\Rightarrow$  Toatal amount paid = $Rs.15600+Rs.1170+Rs.312=Rs.17082.$

The cost of a TV is Rs. $36{,}000$. Manoj decides to pay it in $8$ instalments at $12\%$ simple interest p.a. Calculate his monthly E.M.I and the total amount paid by him.

  1. Rs. $5{,}040$, Rs. $40{,}320$
  2. Rs. $3{,}240$, Rs. $40{,}320$
  3. Rs. $3{,}240$, Rs. $38{,}880$
  4. Rs. $4{,}860$, Rs. $38{,}880$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$\Rightarrow$  Cost of T.V is $Rs.36,000$

$\Rightarrow$  So, $P=Rs.36,000,\,T=1\,year$ and $R=12\%$

$\Rightarrow$  $I=\dfrac{P\times R\times T}{100}=\dfrac{36000\times 12\times 1}{100}=Rs.4320$

$\Rightarrow$  Total amount paid by Manoj = Cost price + Interest = $Rs.36,000+4,320=Rs.40,320$.
$\Rightarrow$  $E.M.I=\dfrac{40320}{8}=Rs.5,040$
$\therefore$   Manoj monthly E.M.I is $Rs.5,040$ and total amount of T.V is $Rs.40,320.$

C Correct answer
Explanation

For $100\%$ finance scheme:


$\text{Processing fee=1% of 4,00,000=Rs. 4,000}$

$\text{Initial payments=0%=0}$

$SI=\dfrac{PRT}{100}=\dfrac{4,00,000\times 12.5\times 1}{100}=Rs.\ 50,000$

Hence, total amount that need to be paid is

$Rs.\ (4,00,000+50,000+4,000)=Rs.\ 4,54,000$

Ramu buys a watch whose cost is Rs. $9{,}000$. He decides to pay Rs. $825$ monthly for a period of $12$ months. Calculate the rate of interest charged.

  1. $12\%$
  2. $5\%$
  3. $10\%$
  4. $15\%$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Here, $P=$ Rs. $9,000,\,T=12$ months $=1$ year and $E.M.I.=$ Rs. $825$.

$\Rightarrow$  $I=\dfrac{P\times R\times T}{100}=\dfrac{9000\times R\times 1}{100}=90R.$
$\Rightarrow$  $E.M.I.=\dfrac{P+I}{\text{Months}}$
$\Rightarrow$  $825=\dfrac{9000+90R}{12}$
$\Rightarrow$   $825\times 12=9000+90R$
$\Rightarrow$   $9900=9000+90R$
$\Rightarrow$  $90R=900$
Thus $R=\dfrac{900}{90}=10\%$
