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

For both the process to be equally efficient it must be needed that percentage for both should be equal.So, we can conclude that,

$70-t\times2=80-5\times t$

$3t=10$

t=3.33 sec.

So, for this time it will be equally efficient
