Answer 1

9 is the number and I have tried it

Answer 2

Step-by-step explanation:

Original Number :

let the unit digit = x

let the tens digit = 9-x (as their sum is 9)

10 (9-x) +1 (x)

90 -10x +x

90 - 9x

Reversed Number :

unit digit = 9-x

tens digit = x

10(x) +1 ( 9-x)

10x +9 -x

9x +9

now A.T.Q

original no.- 27 = reversed no.

90-9x -27 = 9x+9

63 -9x = 9x +9

63-9 = 9x +9x

54 = 18 x

54/18 = x

3 =x .........

So, unit digit is = 3

and tens digit is = 9-3 = 6

hence the required no. is 63
