A) 54.5%

B) 45.5%

C) 45%

D) 60.5%

No. of boys=1100
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%
