Profit and loss contributes 3–5 questions to every SBI PO Prelims Quantitative Aptitude paper — and it's one of the few topics where knowing the formula is only half the battle. The other half is calculation speed. SBI PO questions are designed with numbers that make traditional formula application slow and error-prone.
The shortcuts and tricks in this guide bypass long calculations entirely. They work because they're built on the same underlying mathematics but structured for exam conditions — fast to apply, hard to miscalculate.
- Profit and loss appears 3–5 times in SBI PO Prelims Quantitative Aptitude
- The multiplier method replaces percentage calculations with single multiplication steps
- The successive discount formula — (100−a)(100−b)/100 — solves two-discount questions without two separate calculations
- The dishonest dealer formula finds profit percentage from false weight in one step
- Two weeks of shortcut-based practice (15 questions/day) achieves 90%+ accuracy

The Multiplier Method: Replace Percentages with Direct Multiplication
The most time-consuming part of profit and loss calculations is converting percentages into addition or subtraction steps. The multiplier method eliminates this entirely.
The rule: Express every percentage change as a multiplier.
- 20% profit → multiply CP by 1.20 to get SP
- 15% loss → multiply CP by 0.85 to get SP
- 25% discount → multiply MP by 0.75 to get SP
When multiple percentage changes apply, multiply all multipliers together in one step instead of calculating each change separately.
A shopkeeper buys at ₹500, marks up 40%, then gives 20% discount. SP = 500 × 1.40 × 0.80 = 500 × 1.12 = ₹560. One calculation. No intermediate steps.
Harish from Coimbatore cleared SBI PO 2024 after switching to the multiplier method: "I used to take 90 seconds on profit and loss questions with multiple steps. The multiplier approach brought that down to 25 seconds consistently."
The 4 Essential Profit and Loss Shortcuts for SBI PO
Shortcut 1: Successive Discount Formula
When two discounts are applied one after another, the effective single discount is NOT their sum.
Formula: Effective discount = a + b − (ab/100)
Example: 20% and 10% successive discounts = 20 + 10 − (20×10/100) = 30 − 2 = 28% effective discount
Shortcut 2: Dishonest Dealer Formula
When a dealer uses a false weight, the profit percentage is:
Profit% = (True weight − False weight) / False weight × 100
Example: Dealer uses 900g weight instead of 1000g. Profit% = (1000−900)/900 × 100 = 100/900 × 100 = 11.11%
Shortcut 3: Equal CP Shortcut (Two Items, Same Cost)
When two items are sold — one at x% profit and one at x% loss — the net result is always a loss, equal to (x²/100)%.
Example: Two items at 10% profit and 10% loss each → Net loss = 10²/100 = 1% loss
Shortcut 4: Cost Price from Profit and SP
When SP and profit% are given, CP = SP × 100/(100 + profit%). When SP and loss% are given, CP = SP × 100/(100 − loss%).

Your 2-Week Action Plan
Week 1 — Shortcut Drilling by Type: Practise each shortcut type separately — 15 questions per type per day. For every question, identify which shortcut applies before starting the calculation. Do not use the traditional formula-first approach during this phase.
Week 2 — Mixed Timed Practice: Attempt 20 mixed profit and loss questions daily under timed conditions. Target: under 30 seconds per question by Day 14. Any question exceeding 45 seconds signals a shortcut identification problem — review which type it was and reinforce that shortcut specifically.
In our analysis of 500+ PrepGrind students, those who practised shortcut identification before calculation improved profit and loss accuracy from 63% to 91% within two weeks (PrepGrind internal data, 2024).
