Answer 2

$\texttt{Let the total no. of the questions}$$\texttt{asked in the quiz be x.}$

$\mathtt{Question \; answered \; = 70\%}$

$\texttt{A/q}$

$\texttt{Question not answered = 6}$

$\implies \mathtt{(100\% -70\%) \; of \; Ques \; = 6}$

$\implies \mathtt{30\% \; of \; questions \; = 6}$

$\implies \mathtt{\frac{30}{100} × \; x \; = 6}$

$\implies \mathtt{x \; = 6 × \frac{100}{30}}$

$\implies \texttt{x = 20}$

$\therefore \texttt{Total questions asked in quiz was 20}$$\texttt{ }$
