Correct Answer: 400

Step 1: Understand that the student scored 75% of the maximum marks.
Step 2: Let the maximum marks be represented by 'x'.
Step 3: Write the equation for the score: 75% of x equals 300 marks. This can be written as 0.75 * x = 300.
Step 4: To find 'x', we need to isolate it. We can do this by dividing both sides of the equation by 0.75.
Step 5: Perform the division: x = 300 / 0.75.
Step 6: Calculate the result: 300 divided by 0.75 equals 400.
Step 7: Conclude that the maximum marks of the exam are 400.
