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!
