Question

In an examination 2500 students appeared out which 1100 were girls. 50% of the boys and 40% of the girls passed the examination. What percentage of the candidates failed in the examination?

Answer 1

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%

$Total \: number \: of \: student = 2500 \\ No. \: of \: Girls = 1100 \\ No. \: of \: Boys = 2500 - 1100 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1400 \\ \\ No. \: of \: Boys \: passed = \frac{1400 \times 50}{100} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 700 \\ No. \: of \: Girls \: passed = \frac{1100 \times 40}{100} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 440 \\ \\ Total \: no. \: of \: Students \: passed = 700 + 440 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1140 \\ Total \: no. \: of \: Students \: failed = 2500 - 1140 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1360 \\ \% \: of \: Student \: failed = \frac{1360}{2500} \times 100\% \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{272}{5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 54.4 \\ \\ Ans. \: 54.4\%$
