Answer:
900
Explanation:
Let x be no. of attendees.
No. of students = x/3
No. of female students = x/6 = (1/2)(x/3) = (1/2) no. of students
This implies (1/2) of students are male. So,
No of male students = (1/2)(x/3) = x/6 .......eq (1)
No. of female attendees = 2x/3
No of male attendees = x - (2x/3) = x/3 ...eq (2)
Using eq(1) and eq(2)
No of male non-student attendees = (x/3) - (x/6) = x/6 ....eq(3)
No of male non-student attendees= 150 (Given in question) ....eq(4)
Using eq(3) and eq(4)
=> x/6=150
=> x=150*6
=> x=900 (Answer)
