If the birth rate is 100, the death rate is 10 and the number of individuals in a population group is 1000, then what will be the intrinsic rate of natural increase of the population ?

Assertion : Natality rate increases the population size and population density both. Reason : Natality increase the number of individuals in an area by births.
