Question

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?

Answer 1

I believe that the answer is 10 because the first bottle will be exposed to the light 3 times and then the next will be exposed 4 times and then the next 5 and so on so by the tenth bottle it will have been exposed 12 times by the time she drinks it.
The answer is 10
