find the no.​

Answer 1

HOPE THIS HELPS YOU:

Let one digit of the number be x , then its ten digits digits will be (8-x).

So, given number = 10 (8 - x) +x

= 80 - 10x +x

= 80 - 9x

Now if digits are reversed, then Number obtained = 10x +(8- x)

= 10x +8- x

= 9x + 88

According to question (80-9x)+18 = 9x-+8

98-9x = 9x +8

90 = 18

x = 5

Given number = 80 - 9x

= 80 - 9 x 5

= 80 - 45

= 35

The number is 35.
