The literacy rate of Haryana in the Census of 2011 was:

The correct answer is C, 75.55 per cent. Haryana's literacy rate in 2011 was 75.55 per cent, a little above the national rate of 74.04 per cent. The figure hides a wide gap between the sexes, because male literacy was 84.06 per cent while female literacy was only 65.94 per cent, a difference of about eighteen percentage points. Gurgaon was the most literate district of the state and Mewat, now called Nuh, the least literate.

Option A, 67.91 per cent, is below even the national average and does not match Haryana in 2011. Option B, 72.40 per cent, is placed to catch the candidate who remembers only that the state is a little above India and guesses downwards. Option D, 80.14 per cent, is far too high for a state whose female literacy was below sixty-six per cent. In the census a person aged seven years or above who can both read and write with understanding in any language is counted as literate, so children below seven are left out of the calculation altogether.
