💡 “It’s not about how much you know — it’s about how fast and accurately you solve!”
Maths and Reasoning are the heart of every government exam — from SSC, Banking, Railway, Defence, to State PSCs.
To score high in these sections, you need speed, accuracy, and smart tricks that save your precious time during the exam.
So, here’s your complete guide to Maths & Reasoning shortcut techniques that can turn tough questions into easy ones! 🚀
🔢 Part 1: Maths Shortcut Tricks for Quick Calculation
🧠 1️⃣ Multiplication in Seconds
Trick:
If you multiply any number by 5 —
👉 Just divide it by 2 and add a zero (for even) or .5 (for odd).
Example:
🧮 2️⃣ Square of Numbers Ending with 5
Formula:
Example:
⚡ 3️⃣ Simple Percentage Conversion
| Fraction | Percentage |
|---|---|
| 1/2 | 50% |
| 1/3 | 33.33% |
| 1/4 | 25% |
| 1/5 | 20% |
| 1/6 | 16.66% |
| 1/8 | 12.5% |
| 3/4 | 75% |
Memorize this chart — it’s a lifesaver for profit & loss, SI/CI, and percentage questions!
📏 4️⃣ Simple Interest Trick
If Rate (R) and Time (T) are same for both principal and interest:
👉 SI = (P × R × T) / 100
To quickly double your money:
💡 Use Rule of 72:
Divide 72 by the rate of interest to get approximate doubling time.
Example: 72 ÷ 8% = 9 years (to double your money)
🧮 5️⃣ Average Shortcut
If one item is replaced:
👉 New Average = Old Average + (Change ÷ Total Items)
Useful in SSC CHSL, CGL, and Banking questions.
🧩 Part 2: Reasoning Shortcut Tricks for Logical Accuracy
🔄 1️⃣ Coding-Decoding Trick
-
If letters are shifted forward → Add position value.
-
If shifted backward → Subtract position value.
Example:
“CAT” → “DBU” (each letter +1)
💡 Tip: Always note the difference between letters to decode the pattern easily.
🧠 2️⃣ Blood Relation Shortcut
👉 Use the “+ for male” and “– for female” technique.
Example:
A is the father of B → A(+) → B
C is the daughter of A → A(+) → C(–)
Now you can easily identify relationships step-by-step!
🪜 3️⃣ Syllogism Trick
Replace with symbols:
-
All A are B → A ⊂ B
-
Some A are B → A ∩ B ≠ ∅
Then check common intersections logically.
💡 Tip: Practice with Venn Diagrams for quick visualization.
🧩 4️⃣ Direction Sense Trick
Imagine you’re facing North:
-
Left → West
-
Right → East
-
Back → South
👉 Clockwise = Right turn
👉 Anti-clockwise = Left turn
Visualize with a simple “L” pattern — it works in every reasoning test!
⏱️ 5️⃣ Seating Arrangement & Puzzle Strategy
✅ Read all conditions first.
✅ Fix the most definite position.
✅ Eliminate impossible cases quickly.
✅ Use abbreviations (A, B, C…) to avoid confusion.
💡 Practice at least one puzzle daily from previous year SSC or Banking papers.
