Bank Exam Simplification & Approximation – Page 2 (Premium Guide)
BODMAS • Shortcut Tricks • Fast Calculation • Exam Strategy
🔷 BODMAS Rule
B – Bracket
O – Order (Power/Root)
D – Division
M – Multiplication
A – Addition
S – Subtraction
Shortcut Tricks
- 25 × n = (n ÷ 4) × 100
- 125 × n = (n ÷ 8) × 1000
- 99 × n = 100n − n
- Approximate numbers for speed
Simplification Practice
Q1. 25 × 4 + 10
= 100 + 10 = 110
Q2. 100 ÷ 5 × 2
= 20 × 2 = 40
Q3. 50 + 20 × 3
= 50 + 60 = 110
Q4. (40 + 60) ÷ 5
= 100 ÷ 5 = 20
Q5. 200 − 50 × 2
= 200 − 100 = 100
Q6. 144 ÷ 12 × 3
= 12 × 3 = 36
Q7. 36 × 2 − 10
= 72 − 10 = 62
Q8. (20 + 30) × 2
= 50 × 2 = 100
Q9. 80 − (10 × 5)
= 80 − 50 = 30
Q10. 64 ÷ 8 + 12
= 8 + 12 = 20
🔥 Approximation Practice
Q11. 498 + 302
≈ 500 + 300 = 800
Q12. 999 × 48
≈ 1000 × 48 = 48000
Q13. 203 × 49
≈ 200 × 50 = 10000
Q14. 798 ÷ 4
≈ 800 ÷ 4 = 200
Q15. 52 × 19
≈ 50 × 20 = 1000
