Answer:

Answer of your question

Answer 2

Answer:

32400

Step-by-step explanation:

count of micro organism = 25000

20% increase in 1st hour

so = 25000 × 120/100

10% decrease in 2nd hour

so = 25000 × 120/100 × 90/100

20% increase in third hour

so = 25000 × 120/100 × 90/100 × 120/100

solve the following equation

you will get the answer

32400
