Solution:

√1445 ≈ 38

29.92 × 15 ≈ 30 × 15 = 450

38 + 450 − 222 ≈ 266

? ≈ 266 − 145 ≈ 121 ≈ 120

2. ? = [(696.17 / 16.84) + (7.12 × 16.97)] × 3.12

Correct Answer: (a) 490
Solution:

696.17 / 16.84 ≈ 700/17 ≈ 41

7.12 × 16.97 ≈ 7 × 17 ≈ 119

Sum ≈ 160

160 × 3.12 ≈ 500

Nearest option = 490

3. ? = 47.89 × 12.21 + 976.08 − 242.02

Correct Answer: (c) 1310
Solution:

47.89 × 12.21 ≈ 48 × 12 = 576

576 + 976 − 242 ≈ 1310

4. ? = [23.93 × (5.98^2.03 + 4.03)] / 8.11

Correct Answer: (d) 120
Solution:

5.98^2.03 ≈ 6² = 36

36 + 4.03 ≈ 40

23.93 × 40 ≈ 960

960 ÷ 8.11 ≈ 118 ≈ 120

5. ? = (31.82 × 584.95) / 117.04 + 740.21

Correct Answer: (d) 900
Solution:

(31.82 × 584.95) / 117.04 ≈ (32×585)/117 ≈ 160

160 + 740 ≈ 900

6. 11.98% of 224.99 = 19.99% of ?

Correct Answer: (b) 135
Solution:

11.98% of 224.99 ≈ 0.12 × 225 ≈ 27

? ≈ 27 ÷ 0.20 ≈ 135

7. √483.99 + √? − √360.99 = √840.98

Correct Answer: (a) 676
Solution:

√483.99 ≈ 22, √360.99 ≈ 19, √840.98 ≈ 29

22 + √? − 19 = 29 ⇒ √? = 26

? = 26² = 676

8. 40.09% of 840.02 + 502.96 − 24.09 × 13.98 = ?

Correct Answer: (a) 503
Solution:

24.09 × 13.98 ≈ 24 × 14 ≈ 336

These nearly cancel, so result ≈ 503

9. 654.08 + 18.13 × 15.11 − 363.91 ÷ 13.89 = ?

Correct Answer: (b) 898
Solution:

18.13 × 15.11 ≈ 18 × 15 = 270

363.91 ÷ 13.89 ≈ 364 ÷ 14 ≈ 26

654 + 270 − 26 ≈ 898

10. 564.08 + 933.13 − 845.91 + 634.21 − 302.98 = ?
