Profit & Loss Tricks (Basic + Advanced) – Bank Exams
Concept Clarity • Formula Based • Easy Scoring
1. Basic Concept
- Cost Price (CP) → Buying price
- Selling Price (SP) → Selling price
👉 If SP > CP → Profit ✔
👉 If SP < CP → Loss ✔
2. Important Formulas
Profit = SP - CP
Loss = CP - SP
Profit % = (Profit / CP) × 100
3. Example
CP = 100
SP = 120
👉 Profit = 20
👉 Profit % = 20% ✔
4. Discount Concept
Marked Price (MP) → Original price
Discount → reduction
SP = MP - Discount
5. Important Trick
👉 If Profit = 20%
SP = 120 when CP = 100
Use base value 100 for quick solving
6. Successive Discount
10% + 10% ≠ 20% ❌
👉 Formula:
Final = a + b - (ab/100)
7. Common Mistakes
- Confusing CP and SP ❌
- Wrong percentage calculation ❌
- Ignoring discount logic ❌
8. Topper Tip
Assume CP = 100 for percentage questions. This simplifies calculations.
9. Quick Practice
CP = 200
Profit = 20%
