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 overall simple average of the percentage increase in female literacy to the simple average percentage increase in female literacy of those states where the percentage increase is more than the overall average is .............
Solution
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 average of percentage increase in female literacy of those states where the percentage increase is more than the overall average is
$$\dfrac{28.67+31+26.63+31.2+29.68}{5}=29.436$$
Hence, the ratio is $$\dfrac{26.496}{29.436}=0.90$$
Hence, the answer is Option C.
