5.	The sum of the digits of a 2-digit number is 11. The number obtained byinterchanging the digits exceeds the original number by 27. Find the number.
Answer» GivEn: The sum of the digits of a 2-digit number is 11. The number obtained by interchanging the digits exceeds the original number by 27. To find: Find the number. SoluTion: LETS the digit of the number in one's PLACE be x and the number in ten's place be y. Therefore, the number is xy. As per given Question, The sum of the digits of a 2-digit number is 11. $\implies$ x + y = 11 $\implies$ y = 11 - x⠀⠀⠀⠀⠀(1) If one's and ten's place of the number is x and y respectively. Therefore the number is, $\implies$ 10y + x Now, Put the value of x from eq(1) - $\implies$ 10(11 - x) + x $\implies$ 110 - 10x + x $\implies$ 110 - 9x ★ After interchanging, $\implies$ 10x + y $\implies$ 10x + (11 - x) $\implies$ 11 + 9x ━━━━━━━━━━━━━━━ The number obtained by interchanging the digits exceeds the original number by 27. $\implies$ 11 + 9x = 110 - 9x + 27 $\implies$ 11 + 9x = 137 - 9x $\implies$ 9x + 9x = 137 - 11 $\implies$ 18 = 126 $\implies\sf x = \cancel{ \dfrac{126}{18}}$ $\implies$ x = 7 ★ Now, Put the value of x in eq(1) - $\implies$ y = 11 - 7 $\implies$ y = 4 ━━━━━━━━━━━━━━━ ★ Put ths value of x and y in, $\implies$ 10y + x $\implies$ 10 × 4 + 7 $\implies$ 40 + 7 $\implies$ 47 $\therefore$ Hence, the REQUIRED number is 47.

The sum of the digits of a 2-digit number is 11. The number obtained byinterchanging the digits exceeds the original number by 27. Find the number.

Answer»

GivEn:

The sum of the digits of a 2-digit number is 11.

The number obtained by interchanging the digits exceeds the original number by 27.

To find:

Find the number.

SoluTion:

LETS the digit of the number in one's PLACE be x and the number in ten's place be y.

Therefore, the number is xy.

As per given Question,

The sum of the digits of a 2-digit number is 11.

$\implies$ x + y = 11

$\implies$ y = 11 - x⠀⠀⠀⠀⠀(1)

If one's and ten's place of the number is x and y respectively.

Therefore the number is,

$\implies$ 10y + x

Now, Put the value of x from eq(1) -

$\implies$ 10(11 - x) + x

$\implies$ 110 - 10x + x

$\implies$ 110 - 9x

★ After interchanging,

$\implies$ 10x + y

$\implies$ 10x + (11 - x)

$\implies$ 11 + 9x

━━━━━━━━━━━━━━━

The number obtained by interchanging the digits exceeds the original number by 27.

$\implies$ 11 + 9x = 110 - 9x + 27

$\implies$ 11 + 9x = 137 - 9x

$\implies$ 9x + 9x = 137 - 11

$\implies$ 18 = 126

$\implies\sf x = \cancel{ \dfrac{126}{18}}$

$\implies$ x = 7

★ Now, Put the value of x in eq(1) -

$\implies$ y = 11 - 7

$\implies$ y = 4

━━━━━━━━━━━━━━━

★ Put ths value of x and y in,

$\implies$ 10y + x

$\implies$ 10 × 4 + 7

$\implies$ 40 + 7

$\implies$ 47

$\therefore$ Hence, the REQUIRED number is 47.

Answer» Answer: The NATURE of quadratic equation is no real ROOTS. Step-by-step explanation: Given : Quadratic equation To FIND : Nature of the roots of quadratic equation? Solution : To DETERMINE the nature we find DISCRIMINANT, 1) If D<0, no real roots. 2) If D=0, two equal real roots. 3) If D>0, two distinct real roots. Now, we find discriminant. Here, a=2,b=-4,c=3 So, D<0 there is no real roots. Therefore, The nature of quadratic equation is no real roots.

Step 1 :Let the unit’s digit be x Step 2 :Then, ten’s digit = (9 – x) ∴ Number = 10 × (9 – x) + x ⇒ 90 – 10x + x = (90 – 9x) Step 3 :Adding 27 to the number 90 – 9x, we get 117 – 9x Step 4 :Number with digits interchanged is 10x + (9 – x) = 9x + 9 Step 5 :117 – 9x = 9x + 9 Step 6 :Therefore unit’s digit = 6 and ten’s digit = 3 Step 7 :Hence the number = 36.

45.	8x - 3y = 134x - 3y = 14
Answer» 34x-3y = 1 4 (-) 8x-3y = 1 ------------------------ 26x = 13 X = 2 substitute x VALUE in equation 8(2)-3y = 1 16 - 3y = 1 -3y = 1-16 -3y = -15 y = 5 hope this is HELPFUL

45.

8x - 3y = 134x - 3y = 14

Answer»

34x-3y = 1 4

(-) 8x-3y = 1

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

26x = 13

X = 2

substitute x VALUE in equation

8(2)-3y = 1

16 - 3y = 1

-3y = 1-16

-3y = -15

y = 5

hope this is HELPFUL
