My special number has a 9 in the units column. If I remove the 9 from the units column and place it at the left hand end of the number, but leave all the other digits unchanged, I get a new number. This new number is four times my special number. What is my special number?

So the question above is from an 11+ grammar school entry exam. I've worked out the answer but not without some pain and guesswork thrown in for good measure. I just can't imagine how my kid or any 10 year is supposed to work it out!
