In a survey of 46 shoppers at a mall, 22 bought clothes, 24 bought shoes and 10 bought both. How many shoppers bought clothes only?

  1. 26
  2. 36
  3. 12
  4. 10
Answer

C) 12

At least one = 22 + 24 - 10 = 36; first group only = 12; second group only = 14; exactly one = 26; neither = 46 - 36 = 10. So the answer is 12. SLO M-09-A-14 · Application
