Percentage means "per hundred". Success in Quant depends on how fast you convert percentages into fractions.
x% of y = y% of x
Example: 25% of 48 = 12
• 10%: Shift decimal one place left
• 5%: Half of 10%
• 15%: 10% + 5%
| Exam Scenario | Shortcut Formula |
|---|---|
| Increase / Decrease | Old × (100 ± x) / 100 |
| Successive Change | a + b + (ab / 100) |
| Profit % | (Profit / CP) × 100 |
"Percentage is not just a topic ; it is the foundation of DI, SI-CI, and Profit-Loss."
