Bacteria in the petri dish = 40
Time taken for the bacteria to be doubled =17 hours
To Find:
To Find the number bacteria left after 4 hours = ?
Solution:
By using the proportionality,
After 17 hours the number of bacteria will be 80.
Let the number of bacteria after 4 hours be x
then
Now by cross multiplication
x= 18. 82
