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](https://tex.z-dn.net/?f=x9%2B2x%3D633%5C%5C%0A%5C%5C%0Ax%2A10%2B9%2A1%2B2x%3D633%5C%5C%0A%5C%5C%20%2010x%2B2x%3D633-9%5C%5C%0A%5C%5C%0A12x%3D624%5C%5C%0A%5C%5C%0Ax%3D52)
Hence the original number is 52.
