Question

In a quiz competition, Ravi gave answers of 70% of the questions. He failed to give answers of six questions. Find the total number of questions asked in the quiz competition.

Answer 1

correct answer = 70 %
uncorrect answers = 100 - 70 = 30 %
uncorrect answers = 30 % = 6 question
= 30/6 = 5 %
= 1 question = 5 %
total quiz = 5% ÷ 100% = 20 quiz
20 question asked in competition

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
