Total Questions: 40

1. (45% of 210) / (420% of 240) = (X% of 32) / (15% of 640)

Correct Answer: (a) 28.125
Solution:

45% of 210 = 94.5

420% of 240 = 4.2 × 240 = 1008

LHS = 94.5 ÷ 1008 = (189/2) ÷ 1008 = 189/2016 = 3/32

X% of 32 = (X/100) × 32 = 8X/25

15% of 640 = 96

RHS = (8X/25) ÷ 96 = 8X/2400 = X/300

So, X/300 = 3/32 ⇒ X = 300 × 3/32 = 900/32 = 28.125

2. (358 + 718) + (93 × 20) + 41.66% of 480 − 75% of 12 = ?

Correct Answer: (b) 3127
Solution:

(358 + 718) = 1076

(93 × 20) = 1860

41.66% of 480 = (5/12) × 480 = 200

75% of 12 = 9

Required value = 1076 + 1860 + 200 − 9 = 3127

3. (9/14) of 560 + 12.5% of 64 + 16% of 250 + (73 × 67) = x + 299

Correct Answer: (b) 5000
Solution:

(9/14) of 560 = (560 ÷ 14) × 9 = 40 × 9 = 360

12.5% of 64 = (1/8) × 64 = 8

16% of 250 = 40

73 × 67 = 4891

LHS = 360 + 8 + 40 + 4891 = 5299

5299 = x + 299

x = 5299 − 299 = 5000

4. 11.11% of 729 + 25% of 48 + 62.5% of 88 + 52 = ?

Correct Answer: (a) 200
Solution:

11.11% of 729 = (1/9) × 729 = 81

25% of 48 = 12

62.5% of 88 = (5/8) × 88 = 55

Required value = 81 + 12 + 55 + 52 = 200

5. 66.66% of 66 − 6.25% of 480 + 87.5% of 320 + (13 × 20) = ?

Correct Answer: (c) 554
Solution:

66.66% of 66 = (2/3) × 66 = 44

6.25% of 480 = (1/16) × 480 = 30

87.5% of 320 = (7/8) × 320 = 280

13 × 20 = 260

Required value = 44 − 30 + 280 + 260 = 554

6. 5(15/17)% of 510 + 7(1/7)% of 140 + 11(1/9)% of 81 = ?

Correct Answer: (d) 49
Solution:

5(15/17)% = (5 + 15/17)% = (100/17)%

(100/17)% of 510 = (1/17) × 510 = 30

7(1/7)% = (7 + 1/7)% = (50/7)% = (1/14) of the number

(1/14) of 140 = 10

11(1/9)% = (11 + 1/9)% = (100/9)%

(100/9)% of 81 = (1/9) × 81 = 9

Required value = 30 + 10 + 9 = 49

7. (15² + 45²) × 1/5 + ?% of 220 = 549

Correct Answer: (a) 45%
Solution:

15² = 225 and 45² = 2025

15² + 45² = 225 + 2025 = 2250

2250 × 1/5 = 450

So, 450 + (?% of 220) = 549

?% of 220 = 549 − 450 = 99

? = (99 ÷ 220) × 100 = 45%

8. (5% of 750) + (9% of 4900) + (65% of 220) + (22% of 450) = ?

Correct Answer: (d) 720.5
Solution:

5% of 750 = 37.5

9% of 4900 = 441

65% of 220 = 143

22% of 450 = 99

Required value = 37.5 + 441 + 143 + 99 = 720.5

9. (570 × 32/95 × 3/16) + (14% of 2800) = ?

Correct Answer: (b) 428
Solution:

570 ÷ 95 = 6

So, 570 × 32/95 × 3/16 = 6 × 32 × 3/16 = 6 × 2 × 3 = 36

14% of 2800 = 392

Required value = 36 + 392 = 428

10. 12% of 32 + 16% of 21 + 19% of 17 + 21% of 33 = ?

Correct Answer: (b) 17.36
Solution:

12% of 32 = 3.84

16% of 21 = 3.36

19% of 17 = 3.23

21% of 33 = 6.93

Required value = 3.84 + 3.36 + 3.23 + 6.93 = 17.36
