To calculate the number of each preference:
- 24 youths preferred electronic books
- 109 total people were surveyed, so 109 - 24 = 85 adults were surveyed
- 21 adults preferred printed paper books
- 52 total people preferred electronic books, so 52 - 24 = 28 adults preferred electronic books
- 24 youths preferred electronic books
- 21 adults preferred printed paper books
Therefore:
- The number of youths who preferred printed paper books is 24 - 0 = 24
- The number of adults who preferred electronic books is 28
- The number of adults who preferred printed paper books is 21
- The number of youths who preferred electronic books is 24
- The total number of people who preferred printed paper books is 21 + 24 = 45
- The total number of people who preferred electronic books is 24 + 28 = 52
- The total number of people surveyed is 109.
