Question

The number of bacteria in a certain culture triples every hour. Ifthere were 30 bacteria present in the
culture originally. Then, what would be number of bacteria in the fourth hour?​

Answer 1

810 bacterias are present in the fourth hour.

Given that the bacteria culture triples every hour.

Originally there were 30 bacteria.

After 1 hour there would be (30*3) = 90 bacterias

After the end of 2 hours there would be (90*3) = 270 bacterias

After the end of 3 hours there would be (270*3) = 810 bacterias

So, in the beginning of the fourth hour there are 810 bacterias present.
