The ratio of income of two persons in 9:7 The ratio of their expenses is 4:3 Every person saves rupees 200 find the income of each

Answer»

ANSWER :

The income of 1st person is Rs 1800 and the income of 2nd person is Rs 1400 .

EXPLANATION :

GIVEN :-

The ratio of income of two persons is 9:7.
The ratio of their expenses is 4:3.
Every person saves Rs 200.

TO FIND :-

Income of each person.

SOLUTION :-

Let the income of 1st person be Rs 9x and the income of 2nd person be Rs 7x.

Let the expenditure of 1st person be Rs 4y and the expenditure of the 2nd person be Rs 3y.

Each person saves Rs 200.

★ $\sf{According\:to\:the\: question,}$

$\sf{9x-<klux>4Y</klux>=200..............(i)}$

$\sf{7x-3y=200..............(ii)}$

✪ Multiply 3 with EQ.(i) and 4 with eq.(ii)✪

$\sf{27x-<klux>12Y</klux>=600..............(i)}$

$\sf{28x-12y=800..............(ii)}$

BY ELIMINATION,

27x - 12y = 600

28x - 12y = 800

(-) (+) (-)

__________________

- x = - 200

→ x = 200

✞ Putting x = 200 ✞

Income of 1st person=9×200=Rs 1800.

Income of 2nd person =7×200=Rs 1400.

Therefore, the income of 1st person is Rs 1800 and the income of 2nd person is Rs 1400 .

1 1 1 1 = 82% logic2 2 2 2 = 80%

Answer»

Given : 1 1 1 1= 82 % , 2 2 2 2= 80 % , 3 3 3 3= 95 % , 4 4 4 4= 86 %

To find : 5 5 5 5 = ?

Solution:

1 1 1 1= 82 %

1 + 1 + 1 + 1 = FouR

R is 18th letter of A to Z

100 - 18 = 82

2 2 2 2= 80 %

2 +2 + 2 +2 = EighT

T is 20th letter of A to Z

100 - 20 = 80

3 3 3 3= 95 %

3 +3 + 3 +3 = TwelvE

E is 5th letter of A to Z

100 - 5 = 95

4 4 4 4= 86 %

4 +4 + 4 +4 = SixteeN

N is 14th letter of A to Z

100 - 14 = 86

5 5 5 5 =

5 +5 + 5 +5 = TwentY

Y is 25th letter of A to Z

100 - 25 = 75

=> 5 5 5 5 = 75 %

logic is : add all number and subtract equivalent value of last letter from 100

Good evening......

GIVEN ,

quadratic polynomial = 4s²- 4s +1= p(x)

to find the zeroes of the given quadratic polynomial,

P(x) = 0

4s² - 4s+1 = 0

⇒4s²-2s-2s+1 = 0

⇒2s(2s-1)-1(2s-1) = 0

⇒(2s-1) (2s-1) = 0

Prove that 5/√7 is irrational

Answer»

Answer:

PLEASE MARK ME THE BRAINLIEST CAUSE I AM GOING TO SPEND MUCH OF MY TIME IN THIS QUESTION

Step-by-step explanation:

ANSWER

Let us assume that 5√7 is rational number

Hence 5√7 can be written in the form of a/B where a,b(b ≠0) are co-prime

⟹5√7=a/b

⇒√7=a/5b

But here √7 is irrational but a/5b is rational

as Rational ≠Irrational

This is a contradiction

so 5√7 is a irrational number
