Answer 1

Answer:

So the number is 36 .......

take ones place be x and tense place be y ........

Answer 2

Step-by-step explanation:

Let the digit at Ones place be 'y' and that at tens place be 'x'

Then, Number = 10x + y

Also, Number formed by interchanging the digits = 10y + x

ATQ

x + y = 9...............(1)

(10y +x) = (10x + y) + 27........... (2)

From (2), we get

10y -y = 10x-x + 27

9y = 9x +27

y = x + 3............ (3)

Put value from eq (1) in (3), we get

9-x=x+3

2x=6

x=3

Put x=3 in eq (3)

y=6

Therefore, Answer = 10x+y = 36
