Question

Kevin answered 62 questions correctly on his multiple choice history final and earned a grade of 31%. How many total questions were on the final exam?

Answer 1

Let x be the total number of questions on the final exam.

We know that Kevin answered 62 questions correctly and earned a grade of 31%, which means he got 31% of the total questions correct.
So, 31% of x = 62
0.31x = 62
x = 62 / 0.31
x = 200

Therefore, there were a total of 200 questions on the final exam.
