Answer:
If the doubling time of the given bacterium is 1 day, that means 1 bacterium will multiply to form 2 bacteria.
If the tank is full on the 10th day, it will be half filled one day before i.e. 9th Day.
Example:
Question -
A bacterium doubles in one day. It is inoculated in a container and incubated for 5 days. On the 5th day the container is full. On which day was it half filled.?
Answer -
After 1 day - 1 bacterium will form 2 bacteria.
2nd day - those 2 bacteria will form 4 bacteria.
Day 3 - 4 will form 8
Day 4 - 8 will form 16 (Tank is half)
Day 5 - 16 will form 32 (Tank is full)
In this example the answer is Day 4. So, the answer of your question is 9 Days.
