BANK & INSURANCE (SIMPLIFICATION PERCENTAGE) Part 1

Total Questions: 50

1. 60% of 240 + 20% of 280 = ?

Correct Answer: (b) 200
Solution:

60% of 240 = 0.60 × 240 = 144

20% of 280 = 0.20 × 280 = 56

Required value = 144 + 56 = 200

2. 50% of ? = 45 + 25 × 6

Correct Answer: (a) 390
Solution:

25 × 6 = 150

45 + 150 = 195

50% of ? = 195

? = 195 ÷ 0.50 = 390

3. 40% of 525 + 25% of 340 = ? + 95

Correct Answer: (c) 200
Solution:

40% of 525 = 0.40 × 525 = 210

25% of 340 = 0.25 × 340 = 85

LHS = 210 + 85 = 295

? + 95 = 295

? = 295 − 95 = 200

4. [{(150% of 44) − 11}% of 660] % of 25 = (?)% of 165

Correct Answer: (b) 55
Solution:

150% of 44 = 1.5 × 44 = 66

66 − 11 = 55

55% of 660 = 0.55 × 660 = 363

363% of 25 = 3.63 × 25 = 90.75

So, (?)% of 165 = 90.75

? = (90.75 ÷ 165) × 100 = 55

5. 70% of 540 − 120% of 350 = ? × 6

Correct Answer: (b) −7
Solution:

70% of 540 = 0.70 × 540 = 378

120% of 350 = 1.20 × 350 = 420

378 − 420 = −42

? × 6 = −42

? = −42 ÷ 6 = −7

6. x% of 160 = √[(√675.989) + 110% of 111 + 20.9% of 99.998]

Correct Answer: (a) 8.125
Solution:

√675.989 ≈ 26

110% of 111 = 1.10 × 111 = 122.1

20.9% of 99.998 ≈ 0.209 × 99.998 ≈ 20.9

Inside bracket ≈ 26 + 122.1 + 20.9 = 169

√169 = 13

So, x% of 160 = 13

x = (13 ÷ 160) × 100 = 8.125

7. 22% of 168 − 19% of 320 + 24% of 460 − 13% of 110 = ?

Correct Answer: (c) 72.26
Solution:

 22% of 168 = 0.22 × 168 = 36.96

19% of 320 = 0.19 × 320 = 60.8

24% of 460 = 0.24 × 460 = 110.4

13% of 110 = 0.13 × 110 = 14.3

Required value = 36.96 − 60.8 + 110.4 − 14.3 = 72.26

8. 2189 + 892 − 1207 − ? = 210% of 820 + √1444 × 4

Correct Answer: (b) 0
Solution:

2189 + 892 = 3081

3081 − 1207 = 1874

210% of 820 = 2.10 × 820 = 1722

√1444 = 38, so √1444 × 4 = 38 × 4 = 152

RHS = 1722 + 152 = 1874

1874 − ? = 1874

? = 0

9. 215 × ? = 78% of 550 + 180 × √64 + 11 × 6

Correct Answer: (b) 9
Solution:

78% of 550 = 429

√64 = 8, so 180 × 8 = 1440

11 × 6 = 66

RHS = 429 + 1440 + 66 = 1935

215 × ? = 1935

? = 1935 ÷ 215 = 9

10. 78% of 150 + 168 ÷ √144 − 120% of 45 − ? = 19 × √9

Correct Answer: (c) 20
Solution:

78% of 150 = 117

√144 = 12, so 168 ÷ 12 = 14

120% of 45 = 54

19 × √9 = 19 × 3 = 57

117 + 14 − 54 − ? = 57

77 − ? = 57

? = 20
