Step Type Explanation Answer

1

Problem

What is the total number of students who took the test?

4

2

Step

The provided image shows a frequency table with scores and the number of students who received those scores. By summing the number of students in each score range, we can find the total number of students.

3

Step

Here’s the breakdown:
→ Scores 0 - 10: 2 students.
→ Scores 11 - 20: 5 students.
→ Scores 21 - 30: 8 students.
→ Scores 31 - 40: 10 students.
→ Scores 41 - 50: 6 students.

4

Step

Total Students = 2 + 5 + 8 + 10 + 6 = 31 students.

5

Step

Therefore, The correct answer based on the image is 31.

6

Choice.A

This option is incorrect. It suggests there are 42 students, but based on the fact that option C (31) is correct, the actual number is likely lower

42

7

Choice.B

This option is also incorrect. Similar to option A, it suggests a higher number of students (40) compared to the actual total (31)

40

8

Choice.C

This is the correct answer based on the assumption that the information you have access to (the image) shows a frequency table with student scores and their corresponding counts. If we sum the number of students across all score ranges, we should get 31

31

9

Choice.D

This option is incorrect. While it’s closer to the actual number (31) compared to options A and B, it’s still not the exact total based on your confirmation

35
