Question

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam? 32 40 44 48

Answer 1

44

Explanation:

Let x and y be the total number of questions in part 1 and part 2 exams respectively.

For part 1:

Number of correct question = 4/5 of the total number of question in part 1

`\Rightarrow 16=(4)/(5)* x`

`\Rightarrow x=20`

For part 2:

Number of corrected question = 2/3 of total number of question in part 2

`\Rightarrow 16=(2)/(3)* x`

`\Rightarrow x=24`

So, the total umbers of the questions on Stephanie's exam

=x+y

=20+24

=44

Hence, the total umbers of the questions on Stephanie's exam was 44.
