1336
1136
1236
1363
none of these
Option A
Correct Option: A
1366 + 336 – 666 – 33 + 333 = ?

⇒ 1336 = ?

Hence, option A is correct

10/3
20/3
6
Option C
?% of 3510 = 117

or, (? × 3510 / 117) =100

or, ? = 100 / 30 = 10 / 3

Hence, option C is correct.

3. √(1686 – 317) + √(3440 – 524) = ?
92
95
91
99
none of these
Option C
√(1686 – 317) + √(3440 – 524) = ?

√1369 + √2916 = ?

? = 37 + 54 = 91

Hence, option C is correct

4. 64% of √409600 ÷ 1.6 = ? × 2.56
64
81
10
100
110
Option D
64% of √409600 ÷ 1.6 = ? × 2.56

? × 2.56 = 64% of 640 ÷ 1.6

? × 2.56 = (64 × 640 / 100) ÷ 1.6 = (64 × 640) / 100 × 1.6) = 256

∴ ? = (256/2.56) = 100

Hence, option D is correct.

5. 10*0.5 × √? = 735 ÷ 3
7
49
2401
97
68
Option C
10*0.5 × √? = 735 ÷ 3

5 × √? = 245

√? = 49
? = 2401
Hence, option C is correct

6. 534.255 – 786.55 + 678.45 + 45.324 – 23.122 = ?
448.348
438.438
443.838
438.448
none of these
Option A
534.255 – 786.55 + 678.45 + 45.324 – 23.122 = 448.348

Hence, option (A) is correct.

7. 221 ÷ 23.6 × 94.4 ÷ 169 ÷ 17 = ? ÷ 91
10
28
14
18
17
Option B
221 ÷ 23.6 × 94.4 ÷ 169 ÷ 17 = ? ÷ 91

(221/23.6) × {94.4/ (169 × 17)} × 91 = ?

(4/13) × 91 = ?

? = 28

Hence, option B is correct.

8. 2 + [ 2 – { 2 – 2 ( 2 + 2 ) } ] =?
10
-10
6
-6
none of these
Option A
Given expression = 2 + [2 – {2 – 2 x 4 }]

⇒ 2 + [ 2 – {2 – 8}] ⇒ 2 + [ 2 – (–6)]

⇒ 2 + [2 + 6] ⇒ 2 + 8

⇒ 10.

Hence, option A is correct.

9. 100 × 10 – 100 – 2000 ÷ 100 = ?
290
980
880
780
740
Option C
Given expression = 100 x 10 – 100 – 20

⇒ 1000 – 120

⇒ 880

Hence, option C is correct.

10. 85% of 620 + x% of 480 = 70% of 890
10%
20%
33%
45%
64%
Option B
85% of 620 + x% of 480 = 70% of 890

527 + x × 480 ÷ 100 = 623

x × 4.8 = 623 – 527

x × 4.8 = 96

x = 20%

Hence, option B is correct
