You buy 9999 candies individually wrapped.
For each 5 wrappers, you can get another candy (candy store special!).
What is maximum number of candies that you can eat?
How many wrappers will you have left (less than 5 of course)?
I'm a man of few words, BUT I use 'em often!!

10,248 candies eaten with 3 wrappers left. Oops, one fifth of 10,000 is not 200.

As I've grown older, I've found that my memory is not as good as I used to think it was.

Thanks all; I get 12,498 (same as CCbomber) but with 2 left over. My method (r = remainder):
9999 / 5 = 1999 r4
(1999+4) / 5 = 400 r3
(400+3) / 5 = 80 r3
(80+3) / 5 = 16 r3
(16+3) / 5 = 3 r4
(3+4) / 5 = 1 r2***
9999 + 1999 + 400 + 80 + 16 + 3 + 1 = 12,498 *** leftover wrappers. Where am I missing a leftover wrapper?

Rats! Mrs Worrier agrees with you, CCb Surprising how a seemingly easy problem can cause so much grief... 
To waste one second of one's life is a betrayal of one's self.
I wonder what's on television...?

Ahhh... thanks CCB...made me laugh; that's quite shrewd !!
I had written a short looper/recursive program to handle
any given case...forgot to convert last candy/candies
to wrappers at the last step...
