(a) 13

(b) 30

(c) 10.7

(d) 39

I got this question in class test.

My question comes from Population Growth topic in portion Organisms and Populations of Biology – Class 12

Answer 1

The correct answer is (c) 10.7

To explain I would say: As per the formula, Natality = \(\frac{Number \, of \, deaths \, per \, year}{Mid-year \, population}\) x 1000 = \(\frac{75}{7000}\)  1000 = 10.7

                            The birth rate of the given area is 10.7 per year.
