Question from TRACEY, a parent:
this is the question:
I AM A FOUR-DIGIT POSITIVE INTEGER SUCH THAT THE SUM OF MY DIGITS IS 18 AND MY DIGITS REVERSED ARE EXACTLY FOUR TIMES GREATER THAN MYSELF. WHAT NUMBER AM I?

Well, I'm not going to spoil a question that nice by just giving you the answer!

Hint: Can the first digit be odd?
How large can the first digit be?
What is the first digit?
What can the last digit be?

Good Hunting!
