The overall literacy rate in india is fifty-five percent. a. true b. false

This is false if you are talking about the present day. The overall literacy rate for Indians aged fiften and older in 2018 (latest figures) was seventy-four percent.

It is important to note, however, that literacy is very unevenly spread in India. There are differences in:

gender (men are substantially more literate then women),geography (Kerala is the most literate state in India, with close to ninety-five percent, while Bihar is the least literate one, with around sixty-five percent),urban development (the literacy rate is lower in rural areas than in cities).
