31. 75% of 180 + 150% of 110 − √169 × 12 = ? − 116

Correct Answer: (b) 260
Solution:

75% of 180 = 135

150% of 110 = 165

√169 × 12 = 13 × 12 = 156

LHS = 135 + 165 − 156 = 144

144 = ? − 116

? = 144 + 116 = 260

32. 80% of 320 + 30% of √12100 + ?% of 40 = √9 × 443

Correct Answer: (a) 2600
Solution:

80% of 320 = 256

√12100 = 110, so 30% of 110 = 33

√9 × 443 = 3 × 443 = 1329

256 + 33 + (?% of 40) = 1329

?% of 40 = 1329 − 289 = 1040

? = (1040 ÷ 40) × 100 = 2600

33. 720 ÷ 8 + 25% of 680 + 15% of 60 + 30% of 40 = ?

Correct Answer: (b) 281
Solution:

720 ÷ 8 = 90

25% of 680 = 170

15% of 60 = 9

30% of 40 = 12

Required value = 90 + 170 + 9 + 12 = 281

34. 8800 ÷ √484 + ? + 12 × 15 = 160% of 360

Correct Answer: (b) −4
Solution:

√484 = 22

8800 ÷ 22 = 400

12 × 15 = 180

160% of 360 = 1.6 × 360 = 576

400 + ? + 180 = 576

? = 576 − 580 = −4

35. (64 ÷ 126) × (315 ÷ 16) × ? = 40% of 150

Correct Answer: (c) 6
Solution:

40% of 150 = 60

(64 ÷ 126) × (315 ÷ 16) = (64×315) ÷ (126×16)

Simplify: 64/16 = 4 and 315/126 = 5/2

So the product = 4 × (5/2) = 10

10 × ? = 60

? = 60 ÷ 10 = 6

36. ?% of 625 + 130 ÷ 5 = 80% of 720 + 29 × 50

Correct Answer: (c) 320
Solution:

130 ÷ 5 = 26

80% of 720 = 576

29 × 50 = 1450

RHS = 576 + 1450 = 2026

?% of 625 + 26 = 2026

?% of 625 = 2000

? = (2000 ÷ 625) × 100 = 320

37. (17)² − 20% of 400 + √324 = ?

Correct Answer: (a) 227
Solution:

17² = 289

20% of 400 = 80

√324 = 18

Required value = 289 − 80 + 18 = 227

38. 20% of 650 × 25% of 160 = ? × 100

Correct Answer: (d) 52
Solution:

20% of 650 = 130

25% of 160 = 40

LHS = 130 × 40 = 5200

? × 100 = 5200

? = 5200 ÷ 100 = 52

39. 126 ÷ √49 + ? × 12 = 75% of 320 + 15 × 2

Correct Answer: (d) 21
Solution:

√49 = 7

126 ÷ 7 = 18

75% of 320 = 240

15 × 2 = 30

RHS = 240 + 30 = 270

18 + 12? = 270

12? = 252

? = 252 ÷ 12 = 21

40. √529 × 5 + 80% of 135 = ? + 15% of 180

Correct Answer: (b) 196
Solution:

√529 = 23

23 × 5 = 115

80% of 135 = 108

LHS = 115 + 108 = 223

15% of 180 = 27

223 = ? + 27

? = 223 − 27 = 196
