Question

exam 2500 students of appeared and 8% of students fail how many students passed the examination​

Answer 1

Step-by-step explanation:

2500students

girls are 1100

and

⇒boys are(2500−1100)=1400⇒ 100

50 ×1400=700 boys are passin exam⇒ 100

40 ×1100=440 girls arepassin exam

then,2500−(700+440)=2500−1140

1360 students are failed in exam

Answer 2

Step-by-step explanation:

8 percent failed.

It means that 8 out of 100 failed the examination.

I means that 8/100 of 2500 failed.

100 is taken as 2500 and to find the 8% of it,

we just use the 'of'

So the number of students who failed are:

8/100 of 2500

=25 x 8(zeros will neutralize)

=200 students failed.

Now then in an examination there are oy 2 types of people- failures and passers.

Now if the given amount of the total students is failed, then the remaining would obviously be the passed students.

That is,

2500-200

2300 students passed.
