Question: 366

3. In a group of friends, 17 people are on the chess team, 13 people are in the band, and 8 people are both in the band and on the chess team. How many people are in the group of friends?

  • A. 18
  • B. 19
  • C. 22
  • D. 24

Correct Answer: C

Explanation:

C is correct. 8 people are both on the chess team and in the band. That means that there are 17 − 8 = 9 additional chess players and 13 − 8 = 5 additional band members. 8 + 9 + 5 = 22 people in the group.
