Still working on the test. At first glance you know that at least one third of the class is still working on it (half the girls are one third of the class). And since over half the boys have finished, you know the total remaining is less than half.
You can figure it out using any numbers to set it up, but let's use 20 girls and 10 boys as the simplest. So 10 girls and 8 boys have finished for a total of 18, which leaves 12 still working on it. 12/30 is 6/15ths which is 2/5ths which is the same as 40%.
