11. ? − 19.98% of 1799.99 = 479.99% of 39.98 + 169.98 ÷ 9.99

Correct Answer: (c) 569
Solution:

19.98% of 1799.99 ≈ 0.20 × 1800 = 360

479.99% of 39.98 ≈ 4.8 × 40 = 192

169.98 ÷ 9.99 ≈ 17

RHS ≈ 192 + 17 = 209

? ≈ 209 + 360 = 569

12. 24.99% of 359.98 + 199.98% of 35.01 = ?% of 799.98

Correct Answer: (b) 20
Solution:

24.99% of 359.98 ≈ 0.25 × 360 = 90

199.98% of 35.01 ≈ 2 × 35 = 70

Sum ≈ 160

?% of 799.98 ≈ 160 ⇒ ?% ≈ (160/800)×100 = 20%

13. ? = 52,09^2.01 ÷ (12.97 × 25.99) + 25.91% of (34.96 × 20.11)

Correct Answer: (b) 190
Solution:Let's break it down:
52,09^2.01 ≈ 52² = 2704
12.97 × 25.99 ≈ 13 × 26 = 338
34.96 × 20.11 ≈ 35 × 20 = 700
25.91% ≈ 26%

So, ? ≈ 2704 ÷ 338 + 26% of 700
=> ? ≈ 8 + 182
=> ? ≈ 190

14. ? = 27.91% of (36.2 × (144.01 + 5.95))

Correct Answer: (c) 1512
Solution:

144.01 + 5.95 ≈ 149.96 ≈ 150

36.2 × 150 ≈ 5430

27.91% of 5430 ≈ 0.2791 × 5430 ≈ 1515 ≈ 1512

15. ? = {(18.95 × 108.08) ÷ 75.95} + 70.91 × 12.01

Correct Answer: (d) 879
Solution:

(18.95 × 108.08) ÷ 75.95 ≈ 27

70.91 × 12.01 ≈ 71 × 12 ≈ 852

Total ≈ 27 + 852 ≈ 879

16. ? = (153.98 × 198.06) ÷ (22.02^1.98) + 12.86 × 14.07

Correct Answer: (c) 245
Solution:

22.02^1.98 ≈ 22^2 ≈ 484

(153.98 × 198.06) ÷ 484 ≈ 63

12.86 × 14.07 ≈ 13 × 14 ≈ 182

Total ≈ 63 + 182 ≈ 245

17. ? = 9.96% of 64.93% of 6799.98 + 32.96% of 849.81

Correct Answer: (a) 723
Solution:

64.93% of 6799.98 ≈ 0.6493 × 6800 ≈ 4415

9.96% of 4415 ≈ 0.0996 × 4415 ≈ 440

32.96% of 849.81 ≈ 0.3296 × 850 ≈ 280

Total ≈ 440 + 280 ≈ 720 ≈ 723

18. ? = 4782.24 + 1476.87 − 8.86²

Correct Answer: (b) 6180
Solution:

8.86² ≈ 78.5

6259.11 − 78.5 ≈ 6181 ≈ 6180

19. ? = 43.88% of 1399.73 + 12^2.02 − 264.22
