Question 115

In a school, 60% of the numberof students are boys and the rest are girls. If 20% of the number of boys failed and 65% of the number of girls passed the examination, then the percentage of the total number of students who passed is:

Solution

Let total number of students in school = 100

=> Number of boys = 60 and number of girls = 40

Boys who passed = $$\frac{80}{100}\times60=48$$

Girls who passed = $$\frac{65}{100}\times40=26$$

$$\therefore$$ Total percentage of students passed = $$48+26=74\%$$

=> Ans - (C)
