Davina has a large cellar for her wine bottles and also a small fridge dedicated to wine storage in her kitchen. Davina drinks one bottle per day. Being very fussy, she does not like any bottle of her wine to be exposed to the light more than 12 times, including the time she first transfers it to her cellar, each time the cellar door is opened, each time the fridge door is opened and, finally, on the day when she drinks it. To avoid wasting any wine, what is the largest number of bottles she should order each time she needs more wine?

Justice Hartman · Answer 1

If she opens the big cellar just to get the wine she needs and store it in her fridge, besides if she only opens the fridge to store the bottles or take a daily one to drink it, then she needs 11 bottles every 11 days.

In those on day 1 the fridge will open 2 times + 10 days that the fridge opens once a day, are 12 times.

Therefore, you should not order more than 11 bottles every 11 days.
