  In a town, 30% are illiterate and 70% are poor. Among the rich 10% are illiterate.
  If there are 100 people in town, 70 are poor and 30 are rich.
  30 are illiterate and 70 are literate.
  Out of 30 rich people, 3 (10% of 30) are illiterate.
  so out of 70 poor people 27 (30-3) are illiterate.
  so % of population of illiterate people which is illiterate = 100*27/70 = 270/7 = 38.57%
