1. What is a Percentage Calculator by Marks Formula?

Definition: This calculator computes the percentage score based on marks obtained out of total marks.

Purpose: It helps students, teachers, and professionals quickly determine percentage scores for tests, exams, or any graded work.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \% \) — Percentage score
• \( \text{Obtained} \) — Marks obtained (unitless)
• \( \text{Total} \) — Total possible marks (unitless)

Explanation: The obtained marks are divided by total marks to get a decimal value, which is then multiplied by 100 to convert to percentage.

3. Importance of Percentage Calculation

Details: Percentage scores provide a standardized way to compare performance across different tests or evaluation systems with varying total marks.

4. Using the Calculator

Tips: Enter the marks obtained and total possible marks. Both values must be positive numbers, and total marks must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Can obtained marks be greater than total marks?
A: Normally no, but the calculator will still compute the percentage (which would be over 100%).

Q2: What if I get zero marks?
A: The calculator will correctly show 0% as the result.

Q3: How many decimal places does it show?
A: The result shows 2 decimal places for precision (e.g., 87.50%).

Q4: Can I use this for weighted averages?
A: No, this is for simple percentage calculations. Weighted averages require additional inputs.

Q5: What if I enter non-numeric values?
A: The calculator requires numeric inputs and will not accept text or special characters.
