11. ? = 49.98% × 999.97 + 19.98% of (34.98)²

Correct Answer: (c) 745
Solution:

49.98%×999.97 ≈ 50%×1000 = 500.

(34.98)² ≈ 35² = 1225.

19.98% of 1225 ≈ 20% of 1225 = 245.

So ? ≈ 500 + 245 = 745.

12. ? = 44.98 × 4.97 + 11.04% of 1299.87

Correct Answer: (d) 368
Solution:

44.98×4.97 ≈ 45×5 = 225.

11.04% of 1299.87 ≈ 11% of 1300 = 143.

So ? ≈ 225 + 143 = 368.

13. 49.99% of 469.99 + 29.98% of 559.98 = ?

Correct Answer: (a) 403
Solution:

49.99% of 469.99 ≈ 50% of 470 = 235.

29.98% of 559.98 ≈ 30% of 560 = 168.

Sum ≈ 235 + 168 = 403.

14. (24.98% of 799.897) × 19.97 = ?

Correct Answer: (b) 4000
Solution:

24.98% of 799.897 ≈ 25% of 800 = 200.

200 × 19.97 ≈ 200 × 20 = 4000.

15. 449.99% of 21.98 + 34.06 × 28.96 = ?

Correct Answer: (c) 1085
Solution:

449.99% of 21.98 ≈ 450% of 22 = 4.5×22 = 99.

34.06×28.96 ≈ 34×29 = 986.

Total ≈ 99 + 986 = 1085.

16. ?² − 2499.98% of 23.98 + (14.98)² = (34.99)²

Correct Answer: (b) 40
Solution:

2499.98% of 23.98 ≈ 2500% of 24 = 25×24 = 600.

(14.98)² ≈ 15² = 225; (34.99)² ≈ 35² = 1225.

So ?² ≈ 1225 + 600 − 225 = 1600 ⇒ ? ≈ 40.

17. 139.98% of 349.99 = ?² − (14.98)³ ÷ 24.98

Correct Answer: (d) 25
Solution:

139.98% of 349.99 ≈ 140% of 350 = 1.4×350 = 490.

(14.98)³ ÷ 24.98 ≈ 15³ ÷ 25 = 3375 ÷ 25 = 135.

So ?² ≈ 490 + 135 = 625 ⇒ ? ≈ 25.

18. 39.99% of 159.98 = ? − 319.99% of 79.99

Correct Answer: (d) 320
Solution:

39.99% of 159.98 ≈ 40% of 160 = 64.

319.99% of 79.99 ≈ 320% of 80 = 3.2×80 = 256.

So ? ≈ 64 + 256 = 320.

19. 13.98² + 6.02² − ? = 174.03 − 3.001³

Correct Answer: (d) 85
Solution:

13.98² ≈ 14² = 196.

6.02² ≈ 6² = 36.

LHS ≈ 196 + 36 − ? = 232 − ?.

3.001³ ≈ 27 (since 3³=27).

RHS ≈ 174.03 − 27 = 147.03.

So 232 − ? ≈ 147 ⇒ ? ≈ 85.

20. 635.99 = ? × 1.99 + 18.99% of 2200.02

Correct Answer: (b) 109
Solution:

18.99% of 2200.02 ≈ 19% of 2200 = 418.

So ?×1.99 ≈ 636 − 418 = 218.

? ≈ 218 ÷ 1.99 ≈ 218 ÷ 2 = 109.
