Question

It is known that the cells of a given bacterial culture divide every $3.5$ hours (on average). If there are $500$ cells in a dish to begin with, how many cells will there be after $12$ hours?

• A. $4653$
• B. $9876$
• C. $5383$
• D. None of these

Answer 1

The correct option is C $5383$

Given that the cells will divide after every $3.5$ hours on average

The number of cells after $12$ hours will be $500\times 2^{\frac{12}{3.5}}=5383$

therefore the correct option is $C$
