Solution:

84.07% of 399.94 ≈ 0.8407 × 399.94 ≈ 336.23

84.12 ÷ 6.91 ≈ 12.17

Total ≈ 336.23 + 144.13 − 12.17 ≈ 468.19

22. 184.08 + 3.13 × 47.91 – (12.99)² = ?

Correct Answer: (c) 163
Solution:

3.13 × 47.91 ≈ 149.96

(12.99)² ≈ 168.74

Total ≈ 184.08 + 149.96 − 168.74 ≈ 165.30 ≈ 163 (nearest option)

23. 70.08% of 59.94 + 83.93 – 69.07 + 7.19 × 27.95 = ?

Correct Answer: (a) 255
Solution:

70.08% of 59.94 ≈ 0.7008 × 59.94 ≈ 42.00

7.19 × 27.95 ≈ 200.90

Total ≈ 42.00 + 83.93 − 69.07 + 200.90 ≈ 257.83 ≈ 255 (nearest option)

24. 97.08 + 12.15 – 42.93 + 91.27 – 47.86 = ?

Correct Answer: (d) 109
Solution:

Combine stepwise: (97.08 + 12.15) = 109.23

109.23 − 42.93 = 66.30

66.30 + 91.27 = 157.57

157.57 − 47.86 = 109.71

25. 7.13 × 57.94 – 9.97% of 1680.09 + 129 = ?

Correct Answer: (b) 370

7.13 × 57.94 ≈ 413.12

9.97% of 1680.09 ≈ 0.0997 × 1680.09 ≈ 167.51

Total ≈ 413.12 − 167.51 + 129 ≈ 374.61 ≈ 370 (nearest option)

26. ? = 19.937% of 8003 + 39.579% of 8003

Correct Answer: (a) 4800
Solution:

Total % = 19.937% + 39.579% = 59.516%

59.516% of 8003 ≈ 0.59516×8003 ≈ 4763 ≈ 4800

27. ? + 68.83 = 34.13 × 12.95 + 28.81

Correct Answer: (b) 402
Solution:

34.13×12.95 ≈ 34×13 ≈ 442

442 + 28.81 ≈ 471

? ≈ 471 − 68.83 ≈ 402

28. 29.98% of ?² = 99.02 + 998.91 ÷ 3.08

Correct Answer: (c) 38
Solution:

998.91 ÷ 3.08 ≈ 324

RHS ≈ 99 + 324 = 423

0.2998×?² ≈ 423 ⇒ ?² ≈ 423/0.30 ≈ 1410

? ≈ √1410 ≈ 38

29. 18.23 × 23.04 ÷ ? + 252 = 329.07

18.23 × 23.04 ÷ ? = 329.07 − 252 = 77.07

18.23 × 23.04 ≈ 18 × 23 = 414

So, 414 ÷ ? ≈ 77 ⇒ ? ≈ 414/77 ≈ 5
