Answer:

  • 50 students

Step-by-step explanation:

Given:

  • 4/9 of students are Science Society members
  • The rest are Mathematics Society members
  • 2/5 of Science Society members are girls = 16 people

Find the number of Science Society members:

  • 2/5x = 16
  • x = 16*5/2 = 40

Find the total number of group members:

  • 4/9x = 40
  • x = 40*9/4 = 90

Find the number of Mathematics Society members:

  • 90 - 40 = 50
