Q. A bacteria undergoes binary fission in every minute. This bacterium can fill up a cup in $1$ hour. In how much time will the cup be half filled?

UP CPMTUP CPMT 2015Biological Classification

Solution:

A bacterial cell divides into two bacterial cells in one minute. In each minute, the number of bacterial cells gets doubled. So, half cup of bacteria will divide all in a minute and double their numbers to fill the cup in another one minute. If it takes $60$ minutes by the bacteria to fill the entire cup, half cup must have been filled in one minute less then $60$ minutes, which is $59$ minutes. After that, in one minute, another half of the cup will be filled.
