Answer:

Let ones digit number be x and tens digit number be y of the original number.

According to the question,

2x = y

Original number = y × 10 + x×1 = 2x × 10 + x

[Since 2x = y]

= 20x + x = 21x

Number after reversing digits,

= x × 10 + y × 1 = 10x + 2x

[Since 2x = y]

= 12x

Also, original number + number after reversing digits = 99

Therefore, 21x + 12x = 99

33x = 99

x = 99/33

x = 3

Hence original number = 21x = 21(3) = 63
