Answers :

1) Answer: A

(15.95 * 17.925) = ? * √899.8 + (5.92 * 3.14)

288 = ? * 30 + 18

? = 9


2) Answer: B

8.11 * √1295 + 18.95 * 23.01 – √120 * 47.91 =?

8 * √1296 + 19 * 23 – √121 * 48 =?

288 + 437 – 528 =?

? = 197


3) Answer: B

7.981 % of 325 + 30.891 % of 699.871 + 127.01 =?

8/100 * 325 + 31/100 * 700 + 127 =?

26 + 217 + 127 =?

370 =?


4) Answer: A

747.03 ÷ √6890 + √170 * 16.91 – 26.16 * √65 =?

747 ÷ √6889 + √169 * 17 – 26 * √64 =?

9 + 221 – 208 =?

22 =?


5) Answer: E

621.11 ÷ 23 + 28.009% of 750.99 =? + 36% of 351.33

621 ÷ 23 + 28% of 751 =? + 36% of 351

27 + 210 =? + 126

237 =? + 126

= 237 – 126

= 111


6) Answer: A

432 – 375 =?

? = 57 approx.


7) Answer: A

36.09% of 449.87 + 23.99% of 150 – 43.93% of 259.99 = ?% of 700

36% of 450 + 24% of 150 – 44% of 260 = ?% of 700

(36/100 × 450) + (24/100 × 150) – (44/100 × 260) = ?% of 700

162 + 36 – 114 =?% of 700

198 – 114 =?% of 700

84 =?% of 700

= 84 × 100/700

= 12


8) Answer: D

(324.8/5) x (490.21/14) =? -3475

(325/5) x (490/14) =? – 3475

? = 65 x 35 + 3475

? = 5750 approx.


9) Answer: B

(20.13)2 – (11.74)2 + (240.17 + 79.75) ÷ x = 259.998

202 – 122 + (240 + 80) / x = 260

320 / x = 260 – 400 + 144

320 / x = 4

x = 320 / 4 = 80

Hence, the required answer =80


10) Answer: D

(18.18 × 3.86 + 7.12 × 6.13 – 22.33) = x + 11.73

(18 * 4 + 7 * 6 – 22) – 12 = x

x = 72 + 42 – 22 – 12

x = 80

Hence, the required answer = 80

Answers :

11) Answer: B

45.432% of 59.923 + 2099.891 ÷ √50.12 – 126.912 = ?

27 + 300 – 127 = ?

? = 200


12) Answer: C

√1090.12 * 1.908 + 1899.908 ÷ √1444.189 = ? – 11.11 * 4.210

66 + 50 = ? – 44

? = 160


13) Answer: A

199.99 % of 109.819 + 325.251 ÷ √169.169 = √625.12 * ?

220 + 25 = 25 * ?

?=9.8


14) Answer: A

6399.912 ÷ √255.879 + 120.12 % of 59.980 =? * 7.908

400 + 72=? * 8

?=59


15) Answer: C

√289 × 14 ÷ 7 = ?2 + (8)1/3 + 28 ÷ 4

17*(14/7) = x2 + 2 + (28/4)

34 – 2 – 7 = x2

x2 = 25

x = 5


16) Answer: B

(13)2 – (9/13) × 39 ÷ 9 + (2)3 = x – (8)2

169 – (9/13)*(39/9) + 8 = x – 64

169 – 3 + 8 + 64 = x

x = 238


17) Answer: D

14 % of 3050 – (5/9) of (7/2.5) of 72 = 23 + x

(14/100)*3050 – (5/9)*(7/2.5)*72 = 23 + x

427 – 112 – 23 = x

X = 292


18) Answer: A

√14399.90 ÷ 60.03 + 139.890 * 11.90 – √256.15 * 105.065 +? =4.07

√14400 ÷ 60 + 140 * 12 – √256 * 105 +? = 4

120 ÷ 60 + 1680 – 16 * 105 +? = 4

2 + 1680 – 1680 +? =4

?= 2


19) Answer: D

(35.88)2 – (79.999)2 + (86.012)2 – √195.99 =?

=> (36)2 – (80)2 + (86)2 – √196 =?

=> 1296 – 6400 + 7396 – 14 =?

=> 2278 =?


20) Answer: D

35.9 % of 499.99 – 4.001% of 1600 + 24.9% of 500.01 = ?

=> 36% of 500 – 4% of 1600 + 25% of 500 = ?

=> 36/100 x 500 – 4/100 x 1600 + 25/100 x 500 = ?

=> 180 – 64 + 125 = ?

=> 241 = ?
