Answer:
first find the number of boys
2500 students - 1100 girls = 1400 boys
now find 50% of the boys. 50% = .50
1400*.50 = 700
now find 40% of the girls, 40% = .40
1100*.40 = 440
now add the 2 percentages:
700+440 = 1140 passed
now find the number who failed
2500 - 1140 = 1360
so 1360/2500 students failed. divide this out to get the percentage.
so .544 = 54.4% of the students failed the exam.
