Answer 2

Step-by-step explanation:

let unit place is x and tens place is 2x

According to question after reversing the digit,

$2x + x \times 10 = (x + 2x \times 10) - 27 \\ 2x + 10x = x + 20x - 27 \\ 12x = 21x - 27 \\ 21x - 12x = 27 \\ 9x = 27 \\ x = 27 \div 9 \\ x = 3$

so original number is,

$x + 2x \times 10 \\ put \: value \: of \: x \\ 3 + 2 \times 3 \times 10 \\ = 3 + 60 \\ = 63$

63 is original number
