gujarat’s most literate citizens are Jains:

The largely business-oriented community, which has a population of around 5.25 lakh in Gujarat, has a staggering 87.08 per cent literacy. This is much above the total literacy figure of 58.86 per cent in the state.

Among the Jains, 88.59 per cent men and 85.52 per cent women are literate. In comparison, there is 58.16 per cent literacy among Hindus, 61.89 per cent among Muslims, 67.70 per cent among Christians, 74.27 per cent among Sikhs, 55.30 per cent among Buddhists and 61.04 per cent among other faiths

as for hindus, those pesky scheduled castes blew it for ya:

The literacy figure among Hindus is higher than only that of Buddhists, who are largely converts from Dalits. Literacy rate of Hindus is bogged down by the low level of literacy among Scheduled Tribes, who constitute nearly 15 per cent of the Hindu population in the state. For example, the figure in largely tribal Dahod district is barely 36 per cent.
