The following data shows the comparative data for state-wise literacy and population growth. Study the data carefully to answer these questions.
The ratio of the simple overall average of the percentage increase in female literacy to the simple overall average of the percentage increase in total literacy is approximately equal to ___.
The overall simple average of the percentage increase in female literacy is
$$\dfrac{23.32+19.48+26.2+28.67+31+26.63+31.2+22.86+25.92+29.68}{10}=26.496$$
The simple overall average of the percentage increase in total literacy is
$$\dfrac{25.17+22.34+27.21+29.19+31.06+27.52+30.17+25.58+25.87+29.61}{10}=27.372$$
Hence, the ratio is $$\dfrac{26.496}{27.372}=0.968$$
Hence, the answer is Option B.
