1. What is a Percentage Calculator for 3 Subjects?

Definition: This calculator computes the percentage score based on marks obtained in 3 subjects, each out of 100.

Purpose: It helps students and educators quickly determine overall performance across multiple subjects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \% \) — Percentage score
• \( Sum \) — Total marks obtained in all 3 subjects
• 300 — Maximum possible marks (3 subjects × 100 each)

Explanation: The sum of marks from all subjects is divided by the total possible marks (300) and multiplied by 100 to get percentage.

3. Importance of Percentage Calculation

Details: Percentage scores provide a standardized way to compare academic performance across different subjects and grading systems.

4. Using the Calculator

Tips: Enter marks obtained in each subject (out of 100). The calculator automatically sums them and computes the percentage.

5. Frequently Asked Questions (FAQ)

Q1: What if my subjects have different maximum marks?
A: This calculator assumes each subject is out of 100. For different maximums, you'll need to normalize the scores first.

Q2: How is this different from average?
A: Percentage shows your score relative to total possible marks, while average is the sum divided by number of subjects.

Q3: Can I use this for more than 3 subjects?
A: No, this is specifically for 3 subjects. The denominator would change based on number of subjects.

Q4: What's considered a good percentage?
A: This varies by institution, but generally: 60-79% is good, 80-89% is very good, 90%+ is excellent.

Q5: Does this calculator round the result?
A: Yes, it displays percentages rounded to 2 decimal places for clarity.
