1/4 of the boys and 1/2 of the girls fail the test.
This corresponds to an equal number of boys and girls.
Then, “1 unit” of boys and “1 unit” of girls fail the test.
There must have been “4 units” of boys and “2 units” of girls present for the test.
6 units = 24 students
1 unit = 4 students
2 units = 8 students
so 8 girls are present for the test.
