Accounting program (was problem solving)
Hi there,
This post seems to be having a bit of a problem getting through so
here it is again...
This is a sort of riddle, and riddles are written to confuse the reader
into thinking that something is true when it really is not true. There
are usually a bunch of statements that are true followed by usually
one statement that pretends to discredit one or more of the previous
statements.
For this particular problem, the students pay 30 dollars total, but
once they get 3 dollars back from the clerk they immediately have
no longer paid 30 dollars so the number 30 should get tossed. After
they get 3 dollars back they have paid a total of 27 dollars so
the remaining math has to begin with 27 dollars, not 30 dollars.
A similar riddle would be since the clerk gave the students back
3 dollars and kept 2 *and* they only paid 27 dollars total (after
getting back the 3 dollars) where did the 2 dollars even come from?
Other examples:
Two US mint coins total 30 cents, and one of them is not a nickel.
What are the two coins?
(This will be easy if you have watched the show "Scrubs" recently,
where they used this old riddle on the show).
One of my old favorites:
"In this one town the barber shaves everyone who does not shave themself.
Since the barber does not shave those who shave themself then who
shaves the barber?"
Note that if the barber shaves himself then he does not shave himself
because he does not shave people who shave themself, but then he
cant shave himself in the first place. If he did shave himself then
he would be one of those people who he does not shave, so the paradox
begins.
Take care,
Al
E boa sorte com sua programacao Euphoria!
