Answer 1

Answer:

If it doubles itself at end of every hour, then 1/2 th bottle will be filled at the end of 9th hour (as it doubles and fills completely at end of 10th hour).

At the end of 6th hour, the fraction of bottle filled = 1 x 1/2 x 1/2 x 1/2 x 1/2 = 1/16 th bottle (As the fraction keeps getting halved when we decrease no of hours)
