Answer

To calculate the percentage of marks scored by the student, we can follow these steps:

### Step 1: Identify the total marks and the marks scored
The total marks for the test are 25, and the marks scored by the student are 21.

### Step 2: Use the percentage formula
The formula to calculate the percentage is:
\[ \text{Percentage} = \left( \frac{\text{Marks Scored}}{\text{Total Marks}} \right) \times 100 \]

### Step 3: Substitute the values into the formula
Substituting the values we have:
\[ \text{Percentage} = \left( \frac{21}{25} \right) \times 100 \]

### Step 4: Perform the division
Calculating the division:
\[ \frac{21}{25} = 0.84 \]

### Step 5: Multiply by 100
Now, multiply by 100 to convert it into percentage:
\[ 0.84 \times 100 = 84 \]

### Step 6: Conclusion
The student's marks in percentage terms is 84%.
