In a town survey of 47 people, 20 speak Urdu at home, 19 speak Punjabi at home and 5 speak both. How many people are in exactly one of the two groups?

  1. 29
  2. 34
  3. 13
  4. 15
Answer

A) 29

At least one = 20 + 19 - 5 = 34; first group only = 15; second group only = 14; exactly one = 29; neither = 47 - 34 = 13. So the answer is 29. SLO M-09-A-14 · Application
