Let number of boys in the school = x Let number of girls in the school = y Number of students participated in the sports = 300 Out of which boys = 100 but given number of boys participated in sports = x/3 => x/3 = 100 => x = 300 Remaining girls = 300 - 100 = 200 => y/2 = 200 => y = 400 Therefore, total number of students in the school = x + y = 300 + 400 = 700Related questions
