In a school, 30% of the students are not participating in any competition. 80% of the students who are participating in the competition are girls. If 4200 boys are participating in the competition, find the total number of students in the class?
Sol. Let total number of students be x Total number of participating students = 70% of x Number of boys who are participating = 20% of 70% of x As per the question, number of boys = 4200 20% of 70% of x= 4200 ⇒ x =4200*100/70*100/20=30,000 Total number of students = 30,000.
