Coffee Loyalty Cards
Options
-
23-10-2009 9:00pm#1Just thought of this one today, so don't know if it's as good as I think it is
In a coffee shop, people are given loyalty cards, that entitles them to one free coffee for every 6 they get. So they essentially get 7 for the price of six. The tokens to stick on the loyalty cards are printed on every coffee cup.
A man visits the coffee shop every day, and only gets one cup of coffee each time, and as soon as he fills up a loyalty card he redeems it the next day.
If he starts a new loyalty card on Day 1, how many days is it until he's filled and redeemed two loyalty cards, and how many coffees has he paid for?0

He only has one cup of coffee a day, but your answer is wrong
And when I say "how many days is it until he's filled and redeemed two loyalty cards" I mean including the days he used the loyalty cards. So your answer in those regards is 14 days, paid for 12, which isn't right 0 -
