22.	A sum of money amounts to ₹ 10240 in 2 years at 6 2/3% per annum, compounded annually. Find the sum.
Answer» Given:- $\sf{A = Rs.10240}$ $\sf{T = 2\:years}$ $\sf{R = 6\dfrac{2}{3}\% = \dfrac{20}{3}\%}$ To FIND:- SUM of money Solution:- We know, $\sf{A = P\bigg(1 + \dfrac{r}{100}\bigg)^t}$ = $\sf{10240 = P\bigg(1 + \dfrac{20}{\dfrac{3}{100}}\bigg)^2}$ = $\sf{10240 = P\bigg(\dfrac{100 + \dfrac{20}{3}}{100}\bigg)^2}$ = $\sf{10240 = P\bigg(\dfrac{300+ 20}{3}\times\dfrac{1}{100}\bigg)^2}$ = $\sf{10240 = P\bigg(\dfrac{320}{3}\times\dfrac{1}{100}\bigg)^2}$ = $\sf{10240 = P\bigg(\dfrac{320}{300}\bigg)^2}$ = $\sf{P = 10240\times \dfrac{300}{320}\times\dfrac{300}{320}}$ = $\sf{P = 9000}$ $\sf{\therefore The\:Sum\:of\:money\:is\:Rs.9000}$ From the solution:- A = Amount P = Principal T = Time R = RATE

22.

A sum of money amounts to ₹ 10240 in 2 years at 6 2/3% per annum, compounded annually. Find the sum.

Answer»

Given:-

$\sf{A = Rs.10240}$
$\sf{T = 2\:years}$
$\sf{R = 6\dfrac{2}{3}\% = \dfrac{20}{3}\%}$

To FIND:-

SUM of money

Solution:-

We know,

$\sf{A = P\bigg(1 + \dfrac{r}{100}\bigg)^t}$

= $\sf{10240 = P\bigg(1 + \dfrac{20}{\dfrac{3}{100}}\bigg)^2}$

= $\sf{10240 = P\bigg(\dfrac{100 + \dfrac{20}{3}}{100}\bigg)^2}$

= $\sf{10240 = P\bigg(\dfrac{300+ 20}{3}\times\dfrac{1}{100}\bigg)^2}$

= $\sf{10240 = P\bigg(\dfrac{320}{3}\times\dfrac{1}{100}\bigg)^2}$

= $\sf{10240 = P\bigg(\dfrac{320}{300}\bigg)^2}$

= $\sf{P = 10240\times \dfrac{300}{320}\times\dfrac{300}{320}}$

= $\sf{P = 9000}$

$\sf{\therefore The\:Sum\:of\:money\:is\:Rs.9000}$

From the solution:-

A = Amount
P = Principal
T = Time
R = RATE

=>raman scored 3 marks more than kaku

=>b = k +7

=> r= k+3

-------------------

heir total scored is 76

=>lets form an equation

=> k+r+b = 76

=> k+[k+3]+[k+7] =76

=> 3k +10 =76

=>3k = 76-10

=>3k =66

=>k =22

-------------------

kaku scored 22marks

r = k +3 b = k+7

= 22+3 = 22+7

=25 marks = 29 marks

42.	Cm. Find the distance coveredrevolutions.rud the diameter of a wheel whose circumference is 176 cm.Find the area
Answer» Answer: Diameter = 56cm Area = 2464 $cm^{<klux>2</klux>}$ Step-by-step EXPLANATION: CIRCUMFERENCE = π D= 176 ⇒ D = 176 / π ⇒ D = ( 176 × 7 ) / 22 ⇒ Diameter = 56 cm ∴ Radius = Diameter / 2 = 56/2 = 28cm Area = π $R^{2}$ ⇒ 22/7 * 28 *28 ⇒ 2464 $cm^{2}$

Cm. Find the distance coveredrevolutions.rud the diameter of a wheel whose circumference is 176 cm.Find the area

Answer»

Answer:

Diameter = 56cm

Area = 2464 $cm^{<klux>2</klux>}$

Step-by-step EXPLANATION:

CIRCUMFERENCE = π D= 176

⇒ D = 176 / π

⇒ D = ( 176 × 7 ) / 22

⇒ Diameter = 56 cm

∴ Radius = Diameter / 2 = 56/2 = 28cm

Area = π $R^{2}$

⇒ 22/7 * 28 *28

⇒ 2464 $cm^{2}$
