(i) Yes the literacy rates of the population have increased since 1951 as shown below.

(ii) India had the highest literacy rates in 2001.

(iii) India traditionally has a patriarchal male dominated society where more importance is given to males. Culturally due to division of labour the males go out of their homes and get better access to education. Poor families due to monetary constraints prefer to send only their sons to school and not their daughters.
