  1. 66
  2. 59
  3. 55
  4. 62

Answer: 66

Solutions:
Let us assume that the total number of people is 100.
28 are young and 72 are old. 65 are literate and 35 are illiterate.
Among the literate, 25% (ie 16.25 are young) and the rest 65-16.25 = 48.75 are old.
Among the old, illiterate will be 72-48.75 = 23.25
So, percentage of old in illiterate will be 23.25/35 * 100, which is approximately 66%
