Total Questions: 50

1. (560.12% of 80.012 − 1260.02 ÷ 7.09 + 320.32) × √326 = ? × 6.032

Correct Answer: (b) 1762
Solution:

560.12% of 80.012 ≈ 5.6012 × 80 ≈ 448

1260.02 ÷ 7.09 ≈ 178

Inside bracket ≈ 448 − 178 + 320 ≈ 590

√326 ≈ 18.05, so product ≈ 590 × 18 ≈ 10620

? ≈ 10620 ÷ 6.032 ≈ 1760 ≈ 1762

2. 12.45% of 521.11 + 1235.45 ÷ 13.02 − 472.2 = ? × 12.02

Correct Answer: (c) −26
Solution:

12.45% of 521.11 ≈ 0.1245 × 521 ≈ 65

1235.45 ÷ 13.02 ≈ 95

65 + 95 − 472.2 ≈ −312

? ≈ −312 ÷ 12.02 ≈ −26

3. (50.11% of 1568.23 ÷ √786.86 × (896.34 ÷ 31.98)) = (?)²

Correct Answer: (d) 28
Solution:

50.11% of 1568.23 ≈ 0.5011 × 1568 ≈ 786

√786.86 ≈ 28.05

896.34 ÷ 31.98 ≈ 28.03

So value ≈ (786 ÷ 28.05) × 28.03 ≈ 785

(?)² ≈ 785 ⇒ ? ≈ √785 ≈ 28

4. (7349.89% of 60.12 ÷ 18.13 + 1322.97) ÷ 28.043 = ?

Correct Answer: (a) 56
Solution:

7349.89% ≈ 7350% = 73.5. 60.12 ≈ 60, 18.13 ≈ 18, 28.043 ≈ 28.

(73.5 × 60) ÷ 18 ≈ 4410 ÷ 18 = 245.

245 + 1323 = 1568.

1568 ÷ 28 ≈ 56

5. (√576.24 of √1764.34 ÷ √323.63) = (?)² − 88.08 × 11.11

Correct Answer: (b) 32
Solution:Let's simplify:
√576.24 ≈ √576 = 24
√1764.34 ≈ √1764 = 42
√323.63 ≈ √324 = 18
88.08 × 11.11 ≈ 88 × 11 = 968

So, (24 of 42 ÷ 18) = (?)² - 968
=> (24 × 42 ÷ 18) = (?)² - 968
=> 56 = (?)² - 968
=> (?)² = 56 + 968
=> (?)² = 1024
=> ? = √1024
=> ? = 32

6. 23.98% of 624.99 = 19.98% of ? + 14.98% of 639.99

Correct Answer: (b) 270
Solution:

Approximate: 23.98%≈24%, 19.98%≈20%, 14.98%≈15%.

24% of 625 ≈ 150.

15% of 640 ≈ 96.

So 20% of ? ≈ 150 − 96 = 54 ⇒ ? ≈ 54 ÷ 0.20 = 270

7. ? + 242.99 − 176.01 = 7.99 × 24.98

Correct Answer: (d) 133
Solution:

7.99×24.98 ≈ 8×25 = 200.

242.99 − 176.01 = 66.98 ≈ 67.

So ? ≈ 200 − 67 = 133.

8. 6.99 × 13.98 + 15.01 × 7.98 − 11.97 × 11.02 = ?

Correct Answer: (a) 86
Solution:

Approximate: 6.99≈7, 13.98≈14 ⇒ 7×14=98.

15.01≈15, 7.98≈8 ⇒ 15×8=120.

11.97≈12, 11.02≈11 ⇒ 12×11=132.

So ≈ 98 + 120 − 132 = 86.

9. (19.98 of 74.98) ÷ 29.99 = ? − 19.98% of 124.99

Correct Answer: (a) 75
Solution:

19.98 of 74.98 ≈ 20×75 = 1500.

1500 ÷ 30 = 50.

19.98% of 124.99 ≈ 20% of 125 = 25.

So ? ≈ 50 + 25 = 75.

10. 49.98% of 499.98 = ? − (24.98% of 799.98) ÷ 9.99

Correct Answer: (c) 270
Solution:

49.98% of 499.98 ≈ 50% of 500 = 250.

24.98% of 799.98 ≈ 25% of 800 = 200.

200 ÷ 9.99 ≈ 200 ÷ 10 = 20.

So ? ≈ 250 + 20 = 270.
