When a class took a math test, 15% of the class failed, 25% made some mistakes (but didn’t fail), and 24 students got perfect scores. How many students were in the class?

40 students were in the class.

Did you know?

Did you know that to determine the total number of students in a class, we can use the information about the percentage of students who failed, made mistakes, and got perfect scores? In this case, if 15% of the class failed and 25% made some mistakes (but didn't fail), then the remaining percentage, 100% - 15% - 25% = 60%, represents the proportion of students who scored perfectly or made no mistakes. Since we know that 24 students got perfect scores, we can set up a proportion: (24 / Total number of students) = (60/100) By cross-multiplying, we get: 24 * 100 = Total number of students * 60 Simplifying further, 2400 = Total number of students * 60 And dividing both sides of the equation by 60, we find that the total number of students in the class is 40. So, there were 40 students in the class who took the math test.
