Question

39. In a class, 60% is girls. After leaveing of 22 girls,
now percent of boys is same as before of,
girls.what was the initial number of students?​

Answer 1

in a class if 60% is girls then boys must be 40% in class

and after leaving 22 girl the percentage of boys equal of girls

then the number of the students in class must be 88

because we have to decrease the 20 percent of girl from the class for the equal percentage of boys in class so if 20 percent is 22 the 1 percent equal to 11 and the total percentage of student are 80 in which 40% is girls and 40% boys

so the 80% of 11 eqaul to 88
