📘 BANK EXAM SPEED MATHS – PAGE 10

🔹 High-Level Speed Tricks

✅ Trick 1: Option Elimination (Advanced)

Instead of solving completely, eliminate incorrect options using approximation.

Example: 49 × 21

• Approximate → 50 × 20 = 1000
• Select option closest to 1000

✅ Trick 2: Digital Root for Quick Verification

Example: 36 × 27 = 972

• 3+6 = 9
• 2+7 = 9
• 9 × 9 = 81 → 8+1 = 9
• 9+7+2 = 18 → 1+8 = 9 ✔

✅ Trick 3: Reverse Calculation

Substitute options back into the question instead of solving forward.
