Practice Questions
Q1. 498 + 302
≈ 500 + 300 = 800
Q2. 999 × 48
≈ 1000 × 48 = 48000
Q3. 203 × 49
≈ 200 × 50 = 10000
Q4. 798 ÷ 4
≈ 800 ÷ 4 = 200
Q5. 52 × 19
≈ 50 × 20 = 1000
Q6. 1001 × 32
= 32000 + 32 = 32032
Q7. 999 × 72
= 72000 − 72 = 71928
Q8. 49 × 51
= 2500 − 1 = 2499
Q9. 75 × 96
= 7500 − 300 = 7200
Q10. 125 × 64
= (64 ÷ 8) × 1000 = 8000
High-Level Questions
Q11. 996 × 104
= (1000 − 4)(100 + 4)
= 100000 − 16 = 103584
Q12. 502 × 498
= (500 + 2)(500 − 2)
= 250000 − 4 = 249996
Q13. 1005 × 995
= (1000 + 5)(1000 − 5)
= 1000000 − 25 = 999975
Q14. 48 × 52
= 2500 − 4 = 2496
Q15. 102 × 98
= 10000 − 4 = 9996
