Therefore, the two-digit number = 10x + y and the reversed number = 10Y + x Given: y = 2x -----------1 Also given: 10x + y + 27 = 10y + x 9y - 9x = 27 y - x = 3 Substitute the value of y from equation 1 in equation 2 2x - x = 3 x = 3 Therefore y = 2x = 2 * 3 = 6 = 10x + y = 10*3 + 6 = 36 hope it helps......

21.

In a 2-digit, digit in units place is tiwce the digit in tens plave. If 27 is added to it .what is the number

Answer»

Let us assume, X is a tenth place digit and y is the unit place digit of a two-digit number.

Therefore, the two-digit number = 10x + y and the reversed number = 10Y + x

Given:

y = 2x -----------1

Also given:

10x + y + 27 = 10y + x

9y - 9x = 27

y - x = 3

Substitute the value of y from equation 1 in equation 2

2x - x = 3

x = 3

Therefore y = 2x = 2 * 3 = 6

= 10x + y = 10*3 + 6 = 36

hope it helps......

34.	the sum of digit of2 digit number is 9 if 27 is substracted from the number we get a 2 digit number qith the sequence of digit change find the no
Answer» Assume the DIGIT in ONES place as x and the digit in tens place is y The original number is (10y + x) Number OBTAINED by reversing the digits = (10x + y) Now check for the condition Given that sum of digits of the number is 9 That is x + y = 9 → (1) Second condition is, number obtained by interchanging the digits is greater than the original number by 27 That is (10x + y) = (10y + x) 27 ⇒ 10x + y – 10y – x = 27 ⇒ 9x – 9Y = 27 ∴ x – y = 3 → (2) Add (1) and (2), we get x + y = 9 x – y = 3 ----------- 2x = 12 ∴ x = 6 Put x = 6 in (1), we get 6 + y = 9 ⇒ y = 9 – 6 = 3 The original number = 10y + x = 10(3) + 6 = 36

34.

the sum of digit of2 digit number is 9 if 27 is substracted from the number we get a 2 digit number qith the sequence of digit change find the no

Answer»

Assume the DIGIT in ONES place as x and the digit in tens place is y

The original number is (10y + x)

Number OBTAINED by reversing the digits = (10x + y)

Now check for the condition

Given that sum of digits of the number is 9

That is x + y = 9 → (1)

Second condition is, number obtained by interchanging the digits is greater than the original number by 27

That is (10x + y) = (10y + x) 27

⇒ 10x + y – 10y – x = 27

⇒ 9x – 9Y = 27

∴ x – y = 3 → (2)

Add (1) and (2), we get

x + y = 9

x – y = 3

-----------

2x = 12

∴ x = 6

Put x = 6 in (1), we get

6 + y = 9

⇒ y = 9 – 6 = 3

The original number = 10y + x = 10(3) + 6 = 36

37.

Ten years ago mohan was thrice as old as ram was, but 10 years hence he will be only twice as old. find mohan''s present age.

Answer»

$\underline {\blue { At \: present : }}$

$Age \: of \: Mohan = x \: years$

$Age \: of \:Ram = y \: years$

$\underline {\pink { 10 \: years \:ago : }}$

$Age \: of \: Mohan = (x - 10) \: years$

$Age \: of \:Ram = ( y - 10 )\: years$

/* According to the PROBLEM GIVEN */

$Mohan's \:age = 3 \times ( Ram's \: age )$

$\implies x - 10 = 3(y-10)$

$\implies x = 3y- <klux>30</klux> + 10$

$\implies x = 3y- 20 \: ---(1)$

$\underline {\orange { After \:10 \: years : }}$

$Age \: of \: Mohan = (x + 10) \: years$

$Age \: of \:Ram = ( y + 10 )\: years$

/* According to the problem given */

$Mohan's \:age = <klux>2</klux> \times ( Ram's \: age )$

$\implies x + 10 = 2(y+10)$

$\implies x = 2y+ 20 - 10$

$\implies x = 2y + 10 \: ---(2)$

/ * From (1) and (2), we GET */

$3y - 20 = 2y + 10$

$\implies 3y - 2y = 20 + 10$

$\implies y = 30$

/* Put y = 30 in equation (1) , we get */

$x = 3 \times 30 - 20$

$\implies x = 90 - 20$

$\implies x = 70$

Therefore.,
