In an examination, 1,100 Boys and 900 Girls appeared, \(50 \%\) percent of the Boys and \(40 \%\) Girls passed the examination. The fail percentage is?
A. 54.5\% B. \(45.5 \%\) C. \(75.4\) D. \(44.5\)
Correct Answer: A
Explanation
Total number of students \(=1100\) \(+900\) No of boys that passed \(=\frac{50}{100}=1100=\) \(550 .\) No of girls that passed \(=\frac{40}{100} \times 900=\) \(360 .\) Total number of students that passed \(=\) \(550+360=910\) Total number of students that failed \(=\) \(2000-910=1090\) Therefore the percentage of student that failed \(=\frac{1090}{2000} \times 100 \%=54.5 \%\).
