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 overall average of the percentage increase in total literacy is
$$\dfrac{25.17+22.34+27.21+29.19+31.06+27.52+30.17+25.58+25.87+29.61}{10}=27.372$$
