Question

In a quiz competition ravi gave answers of 70% of the questions. He failed to give answer of 6 questions. Find the total no of asked in the competituon

Answer 1

Let total no. of questions asked be x,
Correct answers percentage = 70%
Worng answers percentage = 30%
Wrong answers = 6

Equation Formed is
30% of (x) = 6

30/100 of (x) = 6

30/100x = 6

x = 6 X 100/3

x = 20

20 is the correct answer to the following question hope it will help.

Answer 2

$\huge\bold\purple{\bigstar{solution}}$

number of questions he failed to answer=6

percentage of questions he failed to answer=30%(100%-70%)

30%=6

let the total number of questions asked in the quiz competition

be x.

$30\% \: of \: x = 6$

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

$= > \frac{3}{10} \times x = 6$

$= > x = 6 \times \frac{10}{3}$

$= > x = 2 \times 10$

$= > x = 20$

hope this helps you
