calculation puzzle - Number of days to fill the Lake with 1/32th part


There is a lake in which every day some new lotus flowers grow. Their growth follows a pattern; if on a given day there are X flowers, then on the next day there will be 2X flowers will be there. So everyday the number of flowers gets doubled.


Now the main question is:


If the whole lake gets covered with lotus flowers in 13 days, then how many days does it take to cover only 1/32th part of the lake?



Answer



Assuming you mean 1/32th:



It should take 8 days.

On day 9 you'll have 1/16th

On day 10 you'll have 1/8th
On day 11 you'll have 1/4th
On day 12 you'll have 1/2nd
On day 13 you'll have a full lake.
