Answer 2

Answer:

1250

Explanation:

The density of population in figure (a) is less than the density of population in figure (b). Thus, figure (a) shows sparse population while figure (b) shows dense population.

Given that, one sign = 100 persons. Since, there are 10 female signs, there are: 10 x 100 1000 females

Since, there are 8 male signs, there are:

8 x 100 = 800 males

If number of males = 1000,

then number of females =?

Sex ratio = 1000 x1000 =1250

800

The sex ration in this case is favourable.
