Question

In a combined test in Maths and Science 8% failed in both subjects and 12% passed in both subjects. If the total number of students who gave the exam is 500, then number of students who passed in both subjects is ___ and the number of students who failed in both subjects is ___

• A. 60, 40
• B. 40, 60
• C. 50, 60
• D. 50, 70

Answer 1

The correct option is A

60, 40

Percentage of students who failed in both subjects = 8%

Total number of students = 500

Number of students failed in both subjects = $\frac{8}{100}\times 500=40$

Percentage of students who passed in both subjects = 12%

Number of students passed in both subjects = $\frac{12}{100}\times 500=60$
