option c - 45 girls are in jonathan’s class
in this question given is that 30 boys in a class and 60% are girls
this means 100 - 60 = 40% are boys,
now we can find total number of students by putting the numbers in formula percentage which is equal to the number of boys *100 / total number of students.
wherby the total number of students is equal to number of boys * 100 /percentage
= 30 * 100 / 40
= 3000 / 40 = 75 total numbers of students,
now boys + girls = total students
henceforth, total students - boys = girls
75 - 30 = 45
numbe of girls = 45.
