Last year, in a rat population of 600 rats, 60 new rats were added through reproduction in the current year to make a total population of 660 rats. Find the birth rate of this rat population.

0.1 Offspring per rat per year

The correct answer is Option (3) → 0.1 Offspring per rat per year 

The birth rate in a population is a measure of the rate at which new individuals are added to the population through reproduction. It indicates the reproductive capacity and potential growth of the population. To calculate the birth rate, we consider the increase in numbers with respect to the total members of the population.

There are 600 rats in a rat population. 60 new rats were added through reproduction. The population increased to 660 rats we can calculate the birth rate as follows:

Birth Rate =60 /600 = 0.1 Offspring per rat per year
