Total number of students=2500
no of girls= 1100
no of boys= 2500-1100=1400
50% of the boys passed the exam,
no of boys who passed the exam= (1400*50)/100= 700
40% of the girls passed the exam,
No of girls who passed the exam= (1100*40)/100= 440
total no of students who passed= 700+440= 1140
no of students who failed the exam= 2500-1140= 1360
percentage of students who failed the exam= (1360/2500)*100%= 54.4%.
Ans=54.4%
