Explanation:

• As per Census, a person aged seven and above who can both read and write with understanding in any language, is treated as literate. A person, who can only read but cannot write, is not literate. A literate person should be above seven years of age. Hence statement 1 is not correct.
• The literacy rate in the country is 74.04 per cent, 82.14% for males and 65.46% for females. Hence less than two thirds of women are literate. Hence statement 2 is not correct.
• There are wide regional disparities in literacy rate across the states of India. There is a state like Bihar which has lowest (63.82 per cent) literacy and there are states like Kerala and Mizoram which have literacy rates of 93.91 and 91.58 per cent respectively. Hence statement 3 is correct.
