Happy Town had a circus performance during the school holidays. 20% of the people were performers and the rest were audience. Female performers were twice the number of male performers. 60% of the audience were male and there were 1200 more male audience than female audience. After some males left the circus, 20% of the remaining people in the circus were male. How many males left the circus?
Q. Happy Town had a circus performance during the school holidays. 20% of the people were performers and the rest were audience. Female performers were twice the number of male performers. 60% of the audience were male and there were 1200 more male audience than female audience. After some males left the circus, 20% of the remaining people in the circus were male. How many males left the circus?
Denote Total People: Let's denote the total number of people in the circus as T. According to the problem, 20% of the people were performers. Therefore, the number of audience members is 80% of T. Number of audience =0.8×T
Calculate Male and Female Audience: We are given that 60% of the audience were male and there were 1200 more male audience than female audience. Let's denote the number of male audience as Ma and the number of female audience as Fa. We can set up the following equation:Ma=0.6×(Number of audience)Fa=Ma−1200Substituting the expression for the number of audience from Step 1, we get:Ma=0.6×(0.8×T)Fa=0.6×(0.8×T)−1200
Equation for Male and Female Audience: Since Ma is 1200 more than Fa, we can write:0.6×(0.8×T)=(0.6×(0.8×T)−1200)+1200This simplifies to:0.6×(0.8×T)=0.6×(0.8×T)This is a tautology and does not help us find T. We need to find another way to express the relationship between Ma and Fa.
