27.

Two digit number is4 times the sum of its digit and twice the product of the digits .find the number

Answer»

Answer:

36

Step-by-step EXPLANATION:

Let the unit digit be x and TENS digit be y

Therefore the NUMBER is 10y+x

Given number is four times the sum of its digit IMPLIES

10y+x =4(y+x)

10y+x=4y+4x

6y=3x

2y=x.....(1)

Given the number is also twice the product of its digit implies

10y+x =2(yx)

Using eq 1

10y+(2y)=2y(2y)

12y=4y^2

3y=y^2

Y=3

Substitute in 1 to get x

X=2×3

X=6

Therefore the number is 10×3 +6

Answer» Answer: a = 12 and b = -8 Step-by-step explanation: 2x + y - 5 = 0 (a + b)x + (5a + 7B)y -20 = 0 given EQ. is infinite many solution so, a1/a2 = b1/ b2 = c1/c2 2/(a+b) = 1/(5a+7b) = -5/(-20) 2/(a+b) = 1/(5a+7b) = 1/4 on compairing a1/a2 = c1/c2 2/(a + b) = 1/4 2 × 4 = 1(a + b) a + b = 8 -----------------(1) on compairing b1/b2 = c1/c2 1/(5a + 7b) = 1/4 1 × 4 = 1 × ( 5a + 7b) 5a + 7b = 4 ----------------(2) MUTIPLY by 5 in eq. 1 5a + 5b = 40 ----------------(3) on subtract eq 2 from 3 5a + 5b = 40 5a + 7b = 4 - - - .............................. -2b = 16 -b = 16/2 -b = 8 b= -8 put b in eq. 1 a + b = 4 a + (-8) = 4 a - 8 = 4 a = 4 + 8 a = 12

32.

Find the value of a and b for which the pair of linear equations has infinity many solutions : 2x +y. -5 = 0 , (a + b)x + (5a + 7b)y - 20 = 0

Answer»

Answer:

a = 12 and b = -8

Step-by-step explanation:

2x + y - 5 = 0

(a + b)x + (5a + 7B)y -20 = 0

given EQ. is infinite many solution

so, a1/a2 = b1/ b2 = c1/c2

2/(a+b) = 1/(5a+7b) = -5/(-20)

2/(a+b) = 1/(5a+7b) = 1/4

on compairing

a1/a2 = c1/c2

2/(a + b) = 1/4

2 × 4 = 1(a + b)

a + b = 8 -----------------(1)

on compairing b1/b2 = c1/c2

1/(5a + 7b) = 1/4

1 × 4 = 1 × ( 5a + 7b)

5a + 7b = 4 ----------------(2)

MUTIPLY by 5 in eq. 1

5a + 5b = 40 ----------------(3)

on subtract eq 2 from 3

5a + 5b = 40

5a + 7b = 4

- - -

..............................

-2b = 16

-b = 16/2

-b = 8

b= -8

put b in eq. 1

a + b = 4

a + (-8) = 4

a - 8 = 4

a = 4 + 8

a = 12

44.	0/एक परीक्षा में एक छात्र को 30 प्रतिशत अंक प्राप्त होते हैं और वह 25 अंकों से असफल होजाता है उसी परीक्षा में दूसरे छात्र को 40 प्रतिशत अंक प्राप्त और उसे उत्तीर्णाक से 25प्रतिशत अंक अधिक मिलते हैं, तो परीक्षा में अधिकतम उत्तीर्णाक ज्ञात करें?
Answer» Answer: PASSING Marks is 175. Step-by-step explanation: Given: Percentage of Marks of 1st student = 30% Marks by which 1st student failed = 25 Percentage of Marks of 2nd student = 40% Marks scored extra by 2nd student = 25 To find: Passing Marks in exam. let x be the total marks of the exam. Marks of 1st Student = $\frac{30}{100}x=\frac{3x}{10}$ Marks of 2nd Student = $\frac{40}{100}x=\frac{4x}{10}$ ACCORDING to the QUESTION, $\frac{3x}{10}+25=\frac{4x}{10}-25$ $\frac{4x}{10}-\frac{4x}{10}=25+25$ $\frac{x}{10}=50$ x = 500 Passing marks = $\frac{3x}{10}+25=3times50+25=175$ Therefore, Passing Marks is 175.

Answer»

Answer:

PASSING Marks is 175.

Step-by-step explanation:

Given:

Percentage of Marks of 1st student = 30%

Marks by which 1st student failed = 25

Percentage of Marks of 2nd student = 40%

Marks scored extra by 2nd student = 25

To find: Passing Marks in exam.

let x be the total marks of the exam.

Marks of 1st Student = $\frac{30}{100}x=\frac{3x}{10}$

Marks of 2nd Student = $\frac{40}{100}x=\frac{4x}{10}$

ACCORDING to the QUESTION,

$\frac{3x}{10}+25=\frac{4x}{10}-25$

$\frac{4x}{10}-\frac{4x}{10}=25+25$

$\frac{x}{10}=50$

x = 500

Passing marks = $\frac{3x}{10}+25=3times50+25=175$

Therefore, Passing Marks is 175.
