Question

In a class, there are 40% girls. Out of the boys, 80% passed but overall, only 56% students passed. Among the girls, what is the pass percentage?

• A. 12
• B. 15
• C. 20
• D. 25

Answer 1

The correct option is C 20

Let the total number of students be 100, then
Number of girls = 40 and the number of boys = 60
According to question
Total number of students passed = 56
Number of boys passed = 80% of 60 = 48
⇒Number of girls passed = 56 – 48 = 8

Girls’ pass percentage =$\frac{4}{40\times 100}=20$%

Hence, option C is the correct answer.
