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
