A music playlist has 38 songs: 20 are qawwalis, 19 are pop songs and 12 are tagged as both. How many songs are qawwalis only?

  1. 27
  2. 8
  3. 11
  4. 15
Answer

B) 8

At least one = 20 + 19 - 12 = 27; first group only = 8; second group only = 7; exactly one = 15; neither = 38 - 27 = 11. So the answer is 8. SLO M-09-A-14 · Application
