Last year, in a rat population of 600 rats, 600 new rats were added through reproduction in the current year to make a total population of 1200 rats.
Find the birth rate of this rat population.
- A 0.5 Offspring per month
- B 2 Offsprings per year
- C 0.5 Offspring per rat per year
- D 600/1200 offspring per week
Answer & Solution
Correct Answer
(C) 0.5 Offspring per rat per year
Step-by-step Solution
Detailed explanation
Birth rate \( = \frac{\text{New rats}}{\text{Total population}} \) \( = \frac{600}{1200} \) \( = 0.5 \) offspring per rat per year
