The ratio of boys and girls in a class is 1 : 2 and the classroom has 24 students. How many boys would have to be admitted to make ratio of boys to girls 1 : 1? Correct Answer 8

Number of girls = {2/(2 + 1)} x 24 = 16 Number of boys = 24 - 16 = 8 If the number of boys becomes 16, the ratio of boys and girls will be 16 : 16 = 1 : 1 So, the number of boys needed to be admitted = 16 - 8 = 8
