Hey mate! ✨
The sex ratio is the ratio of males to females in a population. In most sexually reproducing species, the ratio tends to be 1:1. This tendency is explained by Fisher's principle. For various reasons, however, many species deviate from anything like an even sex ratio, either periodically or permanently.
The literate population of India has became 4th time from 21% in 1951 to 82 % in 2011.
