Question

Evelyn answered 42 questions correctly on her multiple choice history final and earned a grade of 21%. How many total questions were on the final exam?

Answer 1

200 questions

Explanation:

Given data

Let the total questions be x

so that

21% of x= 42 questions

let us solve for x

21/100*x= 42

0.21*x= 42

0.21x= 42

Divide both sides by 0.21

x= 42/0.21

x= 200 questions

Hence the questions are 200 questions
