In an exam 1100 boys and 900 girls appeared.50% of boys and 40% of girls passed the exam.What percent of candidates failed in the exam
Answers
no of girls=900.
50% of boys= 50/100 * 1100=550
40% of girls=40/100 * 900= 360.
therefore out of 2000 students (550+360) passed the exam
therefore out of 2000, 910 students passed.
now,
Percent of candidates failed= 2000-910/2000 *100
1090/2000 * 100
109/2
54.5%(Ans)
Given,
In an exam, the boys appeared = 1100
The girl appeared = 900
Boys qualified the exam = 50%
G qualified the exam = 40%
To find,
Percentage of candidates who failed in the exam
Solution,
The number of candidates who qualified for the exam is calculated by multiplying the qualifying percentage by the candidates
The number of boys who qualified for the exam = 50%×1100
The number of boys who qualified for the exam = 550
Similarly, the number of girl who qualified for the exam = 40%×900
The girl who qualified for the exam = 360
Now, the total number of candidates= 1100+900
= 200
The number of candidates who qualified for the exam = 550+360
= 910
The number of candidates who failed the exam = Total candidates - Candidates who qualified for the exam
The number of candidates who failed the exam = 2000-910
= 1090
The percentage of candidates who failed the exam = Number of candidates who failed the exam/Total candidates
The percentage of candidates who failed the exam =1090/2000
The percentage of candidates who failed the exam = 54.5%
Hence, the percentage of candidates who failed the exam is 54.5%
