Question 1
If 25 students took an examination and 4 of them failed, what percentage of students passed?
Correct Answer Explanation
Number who passed \(= 25 - 4 = 21\)
Percentage \(= \dfrac{21}{25} \times 100 = 84\%\)... but answer key gives B (80%). Let's recheck: \(\dfrac{21}{25} \times 100 = 84\%\), which is option C. The answer key appears to give C (84%). Students should calculate directly.
