उत्तर
Sex ratio means the number of females per 1000 males in a given population. In India, the sex ratio is calculated in terms of females per 1000 males. The formula to calculate the sex ratio is
Sex ratio = `"Female Population"/"Male Population" xx 1000`
The sex ratio is an important characteristic that helps us to study the population of a given area. For example, when we say that the sex ratio in India is 960, it means that there are 960 girls for every 1000 boys.
