What's the minimum amount of change required...

[Popinjay]

What's the minimum amount of change required so that for any one purchase you will always get quarters back? And by amount I mean counted as one coin, two coins, so one penny is the same as one quarter.

[citanul]

are you assuming that you always have adequate bills as well?

Throw this one in the Probability section IMHO. They wait all day with their calculators and slide rules for a question just like this. It will make them want to sing "Happy, Happy, Joy, Joy!" from Ren & Stimpy for the rest of the day!

Yes. I have no idea what he's asking. I'd also like to know whether this is supposed to be a riddle, or he's planning on carrying around said change for some reason?

I'll bite.

4 - penny
2 - nickle
1 - dime

7 coins.

[astroglide]

i believe he's asking what the minimum amount of change is that he would need to carry in his pocket so that, regardless of purchase price, he would receive all of his change in quarters. e.g. his bill is 3.76, he hands them 5.01, and receives a quarter instead of 2 dimes and 4 pennies.

[citanul]

any answer that includes any quarters is wrong.

alrighty then...

the fool man's way to do it is to list all increments of 1 penny from .01-.99 and see which one requires the most coins to get ONLY quarters back (does he man only 1 quarter from any 1 purchase or that all received change be in quarters...)

im lazy and can't think of the correct theoretical appraoch so i'll just flat out guess 9 coins.

[astroglide]

theoretical approach? the largest amount of "bad change" he could receive is 24 cents, so 1 dime/2 nickels/4 pennies is it, and the most he can pay out and not get a quarter is 24 cents. dime/nickel/penny combo has all of the numbers between 1 and 24 in change.

[freekobe]

You have to be able to give back all amounts between .01 and .24

Obviously, anything with a quarter is wrong. 7 coins is the answer.

You will absolutely need 4 pennies. Then you need two nickels and one dime (so you can give back .09, .14, .19, or. 24)/

Answer 7.

so then its 1 dime 2 nickles and 4 pennies.

still 7 coins.
