Answers
Answer:
68/boys
and
50/ girls.
Step-by-step explanation:
total number of boys=1800
32 percent of boys pass=32/100×1800
32 percent of boys pass =576
total number of girls=1200
50 percent of girls pass=50/100×1200
50 percent of girls pass=600
total number of students=no. of boys +no.of girls
total number of students=1800+1200
total number of students=3000
number of pass students=number of pass boys + no. of pass girls
total number of pass students=576+600
total number of pass students=1176
No. of failed students=No. of total students - No. of pass students
No. of failed students=3000-1176
No. of failed students=1824
Percentage of failed students=no. of failed students × 100/ No.of total students
Percentage of failed students=1824×100/3000
Percentage of failed students=60.8 percent
60.8% students did not pass
