Harrizon [31]

Solution:

Let the original number be  x .

As per the problem I took a number, wrote a 9 to the right of it,

So we have  x9

Again  added the doubled original number to the result.

x9+2x

The resulting sum is 633. so we can write

x9+2x=633\\
\\
x*10+9*1+2x=633\\
\\  10x+2x=633-9\\
\\
12x=624\\
\\
x=52

Hence the original number is 52.
