Question

plz answer fast............................

Answer 1

Hari gave answers of 70% que.

The percentage of answers he didn't give = (100 - 70)% = 30 %.

Now,

Let the total que be x.

Then ques unanswered = 30% of x

Acc to question -

30/100 x = 6

x = 6 ☓ 100/30

x = 20

Hence, 20 question were asked

Answer 2

Hey mate,Here is ur answer

$<i>Percentage of questions Ravi attempted=70%$

Percentage of questions Ravi didn't attempted=100-70

=30%

A/Q

Let the total question be x.

30% of x=6



$\frac{30}{100} \times x = 6$

By -Cross multiplication



$x = 6 \times \frac{100}{30}$



$x = \frac{100}{5}$


x=20 .

So, total question asked=20



2)Total students=45

Absent students=5

Present students=45-5

=40

Students failed to do homework=30% of present students



$= \frac{30}{100} \times 40$


$= \frac{1200}{100}$


=12

Students who did homework=Present students-Who didn't do homework

=40-12

=28.
