In a culture, the bacteria count is 1,00,000. The number is increased by 10% in 2 hours. In how many hours will the count reach 2,00,000, if the rate of growth of bacteria is proportional to the number present?

Explanation

Given,

`(dy)/(dt)​= y`

`(dy)/(dt)​=ay`

`ydy​=adt`

`int ydy​=int adt`

`logy=at+c->(1)`


When `t=0,y=1,00,000` putting in equation `(1)`
