Question

In an examination 1100 boys and 900 girls appeared 50% of the boys and 40% of the girls passed the examination what is the percentage of candidates who failed

Answer 1

Number of boys passed=550
Number of girls passed = 360
So total number of boys and girls who passed in the examination=(550+360 )=910
Now total number of students = 2000
so total no of students who failed in the examination is (2000-910)=1090
So the fail percentage is (1090*100)/2000 = 54.5%
