Question

If a population of $50$ paramecium present in a pool increases to $150$ after an hour, what would be the growth rate of population?

• A. $50$ per hour
• B. $200$ per hour
• C. $5$ per hour
• D. $100$ per hour

Answer 1

Answer: (D)

$100$ per hour

Population of paramecium at time t${}_1$= 50
population of paramecium 1 hour after t${}_2$= 150
Growth rate f population = 150-50 per hour
= 100 per hour

So, the correct answer is 100 per hour.
