7.	9.An agricultural Co-operative society gives agricultural loan to its members at the rate ofsimple interest of 4% per annum. But an interest is to be given at the rate of simple interestof 7.4% per annum for a loan taken from the bank. If a farmer being a member of the Co-operative society takes a loan of 5000 from it instead of taking loan from the bank, thenlet us write, by calculating the money to be saved as interest per annum.
Answer» GIVEN :- Co-operative society gives agricultural loan to its MEMBERS at the rate of simple interest of 4% per annum. Bank gives loan at the rate od 7.4 % per annum. Total loan taken by farmer from Co- operative society = Rs.5000 . To Find :- The money to be saved as interest per annum. Solution :- we know that, when rate is simple interest per annum , SI = (P * R * T)/100 . so, → SI given to Co-operative society = (5000 * 4 * 1)/100 = Rs.200 . and, → SI farmed would have given to bank = (5000 * 7.4 * 1)/100 = Rs.370 . then, → Total money saved by farmer = 370 - 200 = Rs.170 (Ans.)

9.An agricultural Co-operative society gives agricultural loan to its members at the rate ofsimple interest of 4% per annum. But an interest is to be given at the rate of simple interestof 7.4% per annum for a loan taken from the bank. If a farmer being a member of the Co-operative society takes a loan of 5000 from it instead of taking loan from the bank, thenlet us write, by calculating the money to be saved as interest per annum.

Answer»

GIVEN :-

Co-operative society gives agricultural loan to its MEMBERS at the rate of simple interest of 4% per annum.
Bank gives loan at the rate od 7.4 % per annum.
Total loan taken by farmer from Co-
operative society = Rs.5000 .

To Find :-

The money to be saved as interest per annum.

Solution :-

we know that, when rate is simple interest per annum ,

SI = (P * R * T)/100 .

so,

→ SI given to Co-operative society = (5000 * 4 * 1)/100 = Rs.200 .

and,

→ SI farmed would have given to bank = (5000 * 7.4 * 1)/100 = Rs.370 .

then,

→ Total money saved by farmer = 370 - 200 = Rs.170 (Ans.)

ANSWER THE QUESTION IN THE ATTACHMENT☞NO SPAM❌❌☞NO COPIED ANSWER ❌❌☞BETTER IF EXPLAINED TOO✅

Answer»

Required answer :-

QUESTION :

• $If \: (x + \frac{1}{x}) \: = \: \sqrt{7} \: then \: <klux>FIND</klux> \: the \: values \: of \: {x}^{2} + \frac{1}{x {}^{2} } \: and \: x {}^{4} + \frac{1}{x {}^{4} } \\$

Solution :

Given,

• $(x + \frac{1}{x}) \: = \: \sqrt{7}$

To find,

• $values \: of \: {x}^{2} + \frac{1}{x {}^{2} } \: and \: x {}^{4} + \frac{1}{x {}^{4} } \\$

Formula used :

•. (a+b)² = a² + b² + 2ab

Step by step explaination : -

According the question we have to square both the terms -

$x {}^{2} + \frac{1}{x {}^{2} } \: + \: 2x \: \times \: \frac{1}{x} = 7 \: \\$

$x {}^{2} + \frac{1}{x {}^{2} } + 2 \: = \: 7 \: \\ x {}^{2} + \frac{1}{x {}^{2} } = 5$

$Hence, \: <klux>VALUE</klux> \: of \: {x}^{2} + \frac{1}{x {}^{2} } \: is \: 5$

Now again we have to square both for calculating the value of SECOND term.

$(x {}^{2} + \frac{1}{x {}^{2} } ) {}^{2} = 5$

$x {}^{4} + \frac{1}{x {}^{4} } + 2x {}^{2} \times \frac{1}{x {}^{2} } = 25$

$x {}^{4} + \frac{1}{x {}^{4} } + 2 = 25$

$x {}^{4} + \frac{1}{x {}^{4} } = 23$

$Hence, \: value \: of \: x {}^{4} + \frac{1}{x {}^{4} } \: is \: 23$

Find y-6y=-5(1-y)-5

Answer»

${\large{\underbrace{\underline{\bf{Question:-}}}}}$ $\\$

Find y in -6y = -5(1 - y) - 5

${\large{\underbrace{\underline{\bf{Answer:-}}}}}$ $\\$

-6y = -5(1 - y) - 5

-6y = -5 + y - 5

-6y = -10 + y

10 = y + 6y

10 = 7y

y = $\frac{10}{7}$

∴ y = $\frac{10}{7}$

★ NOTE -

In order to GET the answer, use BODMAS RULE

B - Brackets,

O - Open,

D - Division,

M - Multiplication,

A - Addition,

An angle of a parallelogram is one-third of its adjacent angle. What are the measures ofthe angles of the parallelogram?

Answer»

Step-by-step explanation:

In a PARALLELOGRAM ABCD,

LET ∠A be X and ∠B be 2x / 3

∴ ∠A + ∠B = 180°

$⇒ x + 2x / 3 = 180°$

$⇒ 5x / 3 = 180°$

$⇒ x° = 180° × 3 / 5 = 108°$

$∠A = 108° , ∠B = 2 / 3 × 108° = 72$

The sum of 3consecutive even numbers is 132.What is the third number in this sequence?

Answer»

Step-by-step explanation:

Given:-

The sum of 3consecutive even numbers is 132.

To find:-

What is the third number in this sequence?

SOLUTION:-

Let the three CONSECUTIVE even numbers =

2X, 2x+2,2x+4

Their sum = 2x+2x+2+2x+4

=>6x+6

Given that

The sum of 3consecutive even numbers is 132.

=>6x+6=132

=>6x=132-6

=>6x=126

=>x=126/6

=>x=21

now 2x=2(21)=42

2x+2=42+2=44

2x+4=42+4=46

The three consecutive even numbers = 42,44,46

Answer:-

The third even number in the sequence = 46

Check:-

Sum of 42,44,46=42+44+46=132

Used concept :-

The GENERAL form of an even number=2n

Answer» Answer: 8% Step-by-step EXPLANATION: Given, Principle = 4600 rs Period = 5 years Total AMOUNT = 6440 rs Annual RATE of INTEREST = ?% Amount=Principle(P)+SI Amount=Principle+PTR/100 Amount=P(1+TR/100) 6440=4600(1+5*R/100) by solving R=8%

32.

Principal = 4600 rsPeriod = 5 yearsTotal Amount = 6440 rsAnnual rate of interest = ?%

Answer»

Answer:

8%

Step-by-step EXPLANATION:

Given,

Principle = 4600 rs

Period = 5 years

Total AMOUNT = 6440 rs

Annual RATE of INTEREST = ?%

Amount=Principle(P)+SI

Amount=Principle+PTR/100

Amount=P(1+TR/100)

6440=4600(1+5*R/100)

by solving R=8%

What is the number if 23 of 27 equal 25% of a number?

Answer»

Answer:

2484

Hope that this was helpful

Step-by-step explanation:

let the number be x

given that

23 of 27 = 25℅ of x

So,

fitting in equation

≈ 23×27 = 25/100×x

23×27 = x/4 ( reducing 25/100 into LOWEST term which is 1/4 )

= 23×27×4 = x

( TRANSPORTING 4 to left hand SIDE and sign will be CHANGE so divides converts multiplication)

= 2484 = x.

so 2484 is the number.

43.

X- 2y = &3 x + 4 Y =20

Answer»

x - 2y = 3x + 4y = 20

x - 2y = 20

x = 20 - 2y

3x + 4y = 20

3(20 - 2y) + 4y = 20

60 - 6y + 4y = 20

60 - 2y = 20

2y = 40

y = 20

x = 20 - 2y

x = 20 - 40

x = -20

Answer»

Step-by-step EXPLANATION:

Given Question:-

The value of (sin72°/cos 18°)-(sec 32°/cosec58°)

Solution:-

Given that:

(sin72°/cos18°)-(sec32°/cosec58°)

=>[sin(90°-18°)/cos18°]-[sec(90°-58°)/cosec58°]

We know that sin(90°-A)=cos A

Sec (90°-A)=Cosec A

=>(Cos 18°/Cos 18°)-(Cosec 58°/Cosec 58°)

=>1-1

=>0

(or)

(sin72°/cos18°)-(sec32°/cosec58°)

=>[sin72°/cos(90°-72°)]-[sec32°/Cosec(90°-32°)]

We know that

Cos (90°-A)=Sin A

Cosec (90°-A)=Sec A

=>(sin 72°/sin72°)-(Sec 32°/sec32°)

=>1-1

=>0

Answer:-

The value of the given problem =0

Used formulae:-

Sin(90°-A)=Cos A
Cos (90°-A)=Sin A
Sec(90°-A)= Cosec A
Cosec (90°-A)= Sec A
