A bacterium divides every `35` minutes. If a culture containing `10^(5)` cells/ml is grown for `175` minutes. What will be the cell concentration / ml after `175` minutes

A

`32 xx 10^(5)` cells

B

`5 xx 10^(5)` cells

C

`35 xx 10^(5)` cells

D

`175 xx 10^(5)` cells

Text Solution

Verified by Experts

The correct Answer is:
A
`n=(175)/(35)=5 " mts. "2^(n)=2^(5)=32` In the starting total number of cells were `10^(5)`. Therefore, answer is `32xx10^(5)`
