Question

If 10 mins is taken for bacteria to be 25 in number, then how much time will it require to become 75?
Condition: bacteria doubles every min​

Answer 1

Answer:

Explanation:

It is given that the doubling time of the given bacteria is 1 minute. It means the generation time of given bacterial cells is 60 seconds. If it takes 60 minutes to fill a cup, it will take 59 minutes to fill half the cup.  

At 59th minute, the cup will be half-filled and in the 60th minute, the bacterial cell will double up and cup will be full filled.

Answer 2

Answer:

60 Minutes (1 hour)

Explanation:

According to the question-

10 minutes takes to become 25 bacteria, that means 1 minute is required for 2.5 bacteria.

Now, bacteria doubles each minutes...That means 1 minute is required for 1.25 bacteria...

Now it has to be 75 bacteria... So firstly it should we should divide 75 by 1.25 to know the minutes it will take.

So, 75÷1.25=60

That means it will take 60 minutes or 1 hour..
