Expert Answer
girls : boys = 2 :3
and total students are 40
Number of girls = 2/5 x 40 = 2 x 8 = 16
Number of boys = 3/5 x 40 = 3 x 8 = 24
5 new students came so total number of students = 45
if the new ratio should be 4 : 5
then number of girls = 4/9 x 45 = 20
number of boys = 5/9 x 45 = 25
earlier the number of boys was 24 so out of new 5 student 1 student has to be a boy.
