Yes, you can definitely prepare better for the SNAP Quantitative Ability section by keeping a complete formula list with you. Instead of memorising everything randomly, it helps to organise formulas chapter-wise so you can revise faster.

Here is a useful formula list for the SNAP Quant section:

1. Arithmetic
• Percentages → % = (Value/Total) × 100
• Profit & Loss → Profit = SP − CP | Loss = CP − SP
• Discount → SP = MP − Discount
• Simple Interest → SI = (P × R × T) / 100
• Compound Interest → A = P (1 + R/100)^T

2. Ratio & Proportion / Mixtures
• Ratio → a : b = a/b
• Mixture formula → (Quantity × Difference) rule (Alligation)

3. Time, Speed & Distance
• Speed = Distance / Time
• Time = Distance / Speed
• Relative Speed → Same direction: (A − B), Opposite direction: (A + B
• Average speed → (2AB) / (A + B)

4. Time & Work
• Work = Rate × Time
• If A does work in X days → 1 day work = 1/X
• A and B together → 1/x + 1/y formula

5. Numbers
• HCF × LCM = Product of two numbers (for two integers)
• Divisibility rules (2,3,5,9 etc.)
• Sum of n natural numbers → n(n + 1)/2

6. Algebra
• (a + b)² = a² + b² + 2ab
• (a − b)² = a² + b² − 2ab
• a² − b² = (a + b)(a − b)
• Quadratic Equation → x = [−b ± √(b² − 4ac)] / 2a

7. Geometry / Mensuration
• Area of triangle → 1/2 × base × height
• Area of circle → πr²
• Circumference → 2πr
• Surface area of cuboid → 2(lb + bh + hl)
• Volume of cylinder → πr²h

8. Probability & Permutation
• Probability → Favourable / Total outcomes
• Permutation → nPr = n! / (n − r)!
• Combination → nCr = n! / [r! (n − r)!]

9. Data Interpretation
• Percentage change → ((New − Old) / Old) × 100
• Average → Sum of values / Number of values

If you revise these formulas along with short practice every day, your speed in SNAP Quant improves a lot. If you want, I can also share a chapter-wise important question list for quick practice.

All the best.
