Shortcut Techniques • Fast Calculation • Exam Strategy
Concept
Multiplication speed is crucial for clearing bank exams. Instead of direct calculation, use shortcut techniques.
Core Shortcut Formulas
125 × n = (n ÷ 8) × 1000
25 × n = (n ÷ 4) × 100
99 × n = 100n − n
999 × n = 1000n − n
101 × n = 100n + n
Practice Questions
Q1. 125 × 32
= (32 ÷ 8) × 1000 = 4 × 1000 = 4000
Q2. 25 × 48
= (48 ÷ 4) × 100 = 12 × 100 = 1200
Q3. 99 × 84
= 8400 − 84 = 8316
Q4. 999 × 72
= 72000 − 72 = 71928
Q5. 101 × 56
= 5600 + 56 = 5656
Q6. 125 × 64
= (64 ÷ 8) × 1000 = 8 × 1000 = 8000
Q7. 98 × 75
= (100 × 75) − (2 × 75)
= 7500 − 150 = 7350
Q8. 97 × 48
= (100 × 48) − (3 × 48)
= 4800 − 144 = 4656
Q9. 250 × 48
= 25 × 48 × 10
= 1200 × 10 = 12000
Q10. 75 × 96
= (100 − 4) × 75
= 7500 − 300 = 7200
Advanced Techniques
Q11. 48 × 48
= (50 − 2)²
= 2500 − 200 + 4 = 2304
Q12. 49 × 51
= (50 − 1)(50 + 1)
= 2500 − 1 = 2499
Q13. 98 × 102
= (100 − 2)(100 + 2)
= 10000 − 4 = 9996
Q14. 999 × 48
= 48000 − 48 = 47952
Q15. 1005 × 32
= 32000 + 160 = 32160
