Question

The percentage of microorganisms remaining vs. exposure time to autoclave sterilization process follows % = 70-t*2. The percentage of microorganisms remaining vs. exposure time to dry heat sterilization process follows % = 80-t*5. At what time both the methods are equally efficient?

Answer 1

As per the question for both time method to be equally efficient we can use the following concept as

70-2t=80-5t

3t=10

t=3.33 s

So, after t=3.33 s both will be equally efficient
