The percentage of questions correctly answered by the student was 92.5%

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of questions incorrectly answered by the student = 3

Number of questions on the test = 40

2. What percentage did the student answer correctly?

Number of questions correctly answered by the student = Number of questions on the test - Number of questions incorrectly answered by the student

Replacing with the real values:

Number of questions correctly answered by the student = 40 - 3

Number of questions correctly answered by the student = 37

Now, let's calculate the percentage:

Percentage = Number of questions correctly answered by the student / Number of questions on the test * 100

Percentage = 37 / 40 * 100

Percentage = 0.925 * 100

Percentage = 92.5%
