The count of bacteria in a culture grows by 10% in the first hour, decreases by 8% in the second hour and again increases by 12% in the third hour. If the count of bacteria in the sample is 13125000, what will be the count of bacteria after 3 hours?

Given,


Count of bacteria in sample = 13125000


According to increase and decrease of growth rates,


Let count of bacteria after 3 hours = X


So,


=


=


=


Hence,


Count of bacteria after 3 hours will be = 14876400
