Answer 2

Answer:

35

Step-by-step explanation:

Let the ones digit number be 'x'

then tens digit number will be '8-x'

Number = 10(8-x) + x

ATQ,

[10(8-x) + x] +18. = 10(x) + 8-x

80 - 9x +18 = 9x +8

90 = 18x

x=5

Putting value of x in number.

Number = 10(8-5) + 5

Number = 10(3) + 5

Number = 35
