  1. $22470$
  2. $23470$

  4. $25470$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$\Rightarrow$  $P=Rs.20,500,\,R=7\%$ and $T=2\,years$


$\Rightarrow$  $A=P(1+\dfrac{R}{100})^T$


$\Rightarrow$  $A=20500\times (1+\dfrac{7}{100})^2$

$\Rightarrow$  $A=20500\times (\dfrac{107}{100})^2$

$\Rightarrow$  $A=20500\times (1.07)^2$

$\Rightarrow$  $A=20500\times 1.1449$

$\therefore$    $A=Rs.23470.$

Vikram borrowed Rs. $20,000$ for $4\dfrac{1}{2}$ years at $10\%$ per annum, compound annually. How much compound interest would he pay at the end of $4\dfrac{1}{2}$ years?

  1. $30711.22$
  2. $20711.22$
  3. $40711.22$
  4. $10711.22$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

We know the formula,
$A = P\left (1+\dfrac{r}{n}\right)^{n.t}$
Where,
$A =$ total amount
$P =$ principal or amount of money deposited,
$r =$ annual interest rate
$n =$ number of times compounded per year
$t =$ time in years
Given:
$P =$ Rs. $20000, r = 10\%, n = 1$ and $t =$ $4\dfrac{1}{2}$ years
$A = 20000\left (1+\dfrac{0.1}{1}\right)^{1\times 4.5}$
$A = 20000\times 1.1^{4.5}$
$A = 20000\times 1.535561$
$A =$ Rs. $30711.22$
To find interest we use formula $A = P + I$, since $A = 30711.22$ and $P = 20000$ we have:
$A = P + I$
$30711.22 = 20000 + I$
$I = 30711.22 - 20000 = 10711.22$
Interest, I $=$ Rs. $10711.22$

  3. $38250.50$
  4. $48250.50$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Given: $P = 12000, r = 15\%, n = 3$ years
$A = P\left [\left (1+\dfrac{r}{100}\right)^n\right]$

$A =$ Rs. $18250.50$

  2. 18,000.

  3. 11,000.

  4. 8,000.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The discount borne by X is the difference between the face value of the bill and the amount received from the bank. The question asks for the discount on the second bill (8,40,000 discounted for 8,20,000), which is 20,000 total. The remittance logic implies X bears the cost proportional to the funds received.

$\Longrightarrow \dfrac{9x}{100}+\dfrac{6500-x}{100}\times 10=605$
$\Longrightarrow 9x+65000-10x=60500$
$\Longrightarrow x=4500$
$6500-x=6500-4500=2000$

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Formula for calculating the amount of an annuity,


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

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

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

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

$F = 12,160$
