| Calculation Type | Formula Used | Example |
|---|---|---|
| What is X% of Y? | Value = (X / 100) * Y | What is 15% of 1200? (180) |
| X is what % of Y? | Percentage = (X / Y) * 100 | 450 is what % of 600? (75%) |
| Percentage Increase | Change = ((New - Old) / Old) * 100 | Salary hike from 20k to 25k (25%) |
| Percentage Decrease | Change = ((Old - New) / Old) * 100 | Discount from ₹1000 to ₹800 (20%) |
Divide your obtained marks by the total maximum marks, and multiply the result by 100. (e.g. `(450 / 600) * 100 = 75%`).
Percentage Increase is calculated as: `((New Value - Original Value) / Original Value) * 100`.
Subtract the discount percentage from 100, divide by 100, and multiply by original price. For example, a 20% discount on ₹1000 is: `(80 / 100) * 1000 = ₹800`.
Divide the numerator by the denominator and multiply the result by 100. (e.g. `3/4` is `0.75 * 100 = 75%`).
Multiply the number by `(1 + Percentage/100)`. For example, adding 18% GST to ₹100 is: `100 * 1.18 = ₹118`.
