Why Calculation Speed is the #1 Factor in Banking Exams

In banking exams like IBPS PO, SBI PO, and IBPS Clerk, you get less than 40 seconds per question in the Quantitative Aptitude section. Out of this, 15-20 seconds are spent on calculation alone. If you can reduce calculation time to 5-8 seconds, you gain a massive competitive advantage.

At Shortcut Maths Bank Coaching, students who complete our 30-day calculation speed programme solve quant questions 3x faster than when they started.

  • Standard student: 20 seconds per calculation = 15 questions in 20 minutes

  • After 30 days: 8 seconds per calculation = 25+ questions in 20 minutes

  • Difference: 10 extra questions = 10 extra marks = Higher rank

Impact of Calculation Speed:

            Standard student: 20 seconds per calculation = 15 questions in 20 minutes
            After 30 days: 8 seconds per calculation = 25+ questions in 20 minutes
            Difference: 10 extra questions = 10 extra marks = Higher rank

Foundation: What You MUST Memorise

Before starting the 30-day plan, memorise these completely:

You should be able to recall any multiplication instantly. No thinking, no counting.

Essential for number series and simplification.

See our simplification guide for the complete table.

Week 1: Basic Operations Speed

Goal: Solve basic addition, subtraction, multiplication, and division mentally.

  • Practice adding 3-digit numbers mentally: 456 + 378 = ?

  • Break into hundreds, tens, units: 400+300=700, 50+70=120, 6+8=14, Total=834

  • Target: 50 additions in 5 minutes

  • Multiply by 5: Divide by 2, multiply by 10. 68 x 5 = 34 x 10 = 340

  • Multiply by 25: Divide by 4, multiply by 100. 48 x 25 = 12 x 100 = 1200

  • Multiply by 125: Divide by 8, multiply by 1000. 64 x 125 = 8 x 1000 = 8000

  • Multiply by 11: Add adjacent digits. 45 x 11 = 4(4+5)5 = 495

  • Divide by 5: Multiply by 2, divide by 10. 230/5 = 460/10 = 46

  • Divide by 25: Multiply by 4, divide by 100. 300/25 = 1200/100 = 12

  • Divide by 125: Multiply by 8, divide by 1000. 4000/125 = 32000/1000 = 32

Week 2: Fractions, Percentages & Decimals

  • 10% of any number: Move decimal one place left. 10% of 450 = 45

  • 5%: Half of 10%. 5% of 240 = 12

  • 1%: Move decimal two places left. 1% of 375 = 3.75

  • 50%: Half the number. 50% of 688 = 344

  • 25%: Quarter the number. 25% of 480 = 120

  • 75%: Three-quarters. 75% of 320 = 240

  • 15%: 10% + 5%. 15% of 200 = 20 + 10 = 30

  • 20%: Double 10%. 20% of 350 = 70

  • 30%: Triple 10%. 30% of 120 = 36

  • 12.5%: Half of 25%. 12.5% of 400 = 50

  • 33.33%: One-third. 33.33% of 300 = 100

Week 3: Advanced Multiplication & Squares

  • Base Method: 98 x 95 = (100-2)(100-5) = 10000 - 700 + 10 = 9310

  • Cross Method: 23 x 45 = (20+3)(40+5) = 800 + 100 + 120 + 15 = 1035

  • Numbers near 50: 53 x 48 = 2500 + (3-2)50 + (-3)(2) = 2544

  • Square of numbers ending in 5: 65^2 = 6x7 followed by 25 = 4225

  • Square of numbers near 100: 103^2 = 10609 (103+3 = 106, 3^2 = 09)

  • Square roots: Memorise perfect squares up to 50

Week 4: DI & Exam-Level Calculations

  • Ratio comparison: Compare fractions by cross-multiplication

  • Percentage change: (New-Old)/Old x 100. Use approximation

  • Average calculation: Assume a base number, calculate deviations

  • Unit digit verification: Verify answers without full calculation

  • Solve 50 simplification questions daily with timer

  • Attempt 2 DI sets daily (20 questions)

  • Track time per question. Target under 10 seconds for basic calculations

  • Review mistakes and practice weak areas

FAQs

Yes! Our students improve by 50-70% in 30 days with consistent 60-minute daily practice. The key is daily practice without breaks.

Yes, selective Vedic Maths techniques are very helpful. Focus on multiplication, squaring, and division shortcuts. Avoid complex Vedic methods that take longer than standard methods.

Start with simple calculations. Do not use pen and paper for additions under 500 or multiplications under 20x20. Gradually increase difficulty.
