Question

Three hundred students took a test. Out of these students; 28% received an A, 54% scored a B and the remaining just passed. Assuming that no student failed; how many students who just passed?

Answer 1

To find the number of students who just passed, subtract the percentages of those who received an A and B from 100% and then calculate 18% of 300 students, which equals 54 students.

Step-by-step explanation:

Three hundred students took a test. To find the number of students who just passed, we need to calculate the percentage of students who did not receive an A or B.

First, we know that 28% received an A and 54% scored a B. To find the percentage of students who just passed, we subtract these percentages from 100%:

• 100% - 28% - 54% = 18%

Now that we know 18% of the 300 students just passed, we can calculate the number:

• (18/100) * 300 = 54

Therefore, 54 students just passed the test.
