failed candidates is​

Answer 1

100-(50+40)
100-90= 10%

Answer 2

Answer:

54.5% is the percentage of the failed candidates.

Step-by-step explanation:

No of boys appeared for the examination = 1100 boys

No of girls appeared for the examination = 900 girls

No of boys that passed the examination = 50/100 * 1100 = 550 boys

No of girls that passed the examination = 40/100 * 900= 360 girls

Total number of students that appeared for the examination = 900 + 1100 = 2000

Total number of students that passed the examination = 550 + 360 = 910 students

Percentage of candidates who failed the examination = (2000-910) / (2000) * (100)

=> 1090/2000 * 100

=> 109/2

∴ 54.5% is the percentage of the failed candidates.
