    93/67
    99/8
    94/8
    99/13
    None of these

    1). Answer: b)
    ? = [6/4 × 32/8 × 6/16] + [6/16 × 24/8 × 36/4]
    = (9/4) + (81/8) = 99/8

    2. (6160 + 12320) ÷ ? = 660

    35
    22
    25.5
    32.4
    28
    2). Answer: e)
    (6160 + 12320) ÷ ? = 660
    (6160 + 12320) / 660 = 18480/660 = 28

    3. ? × (1047 + 137.5) = 46195.5

    27.4
    26

    39
    28
    3). Answer: d)
    ? × (1047 + 137.5) = 46195.5
    ? = 46195.5 / (1047 + 137.5)
    ? = 46195.5 / 1184.5 = 39


    4. (10 × 10 × 10) / (4 + 4 + 4 + 4) = ?

    59.5
    50.5
    62.5
    67.5
    72.5
    4). Answer: c)
    ? = (10 × 10 × 10) / (4 + 4 + 4 + 4)
    = 1000 / 16 = 62.5


    5). (6/8) + (10/16) + (26/32) + (6/10) = ?

    51/16
    26/9
    29/12
    53/16
    None of these
    5). Answer: e)
    ? = (6/8) + (10/16) + (26/32) + (6/10)
    ? = (3/4) + (5/8) + (13/16) + (3/5)
    ? = 223/80


    6. 8743 + 486 ÷ 18 × 148 = ?

    13729
    12739
    12729
    13279
    None of these
    6). Answer: b)
    ? = 8743 + 486 ÷ 18 x 148
    = 8743 + 27 x 148 = 8743 + 3996 = 12739


    7. [(135)^2 ÷ 15 × 39] ÷ ? = 60×52

    15.18
    16.18
    17.18
    19
    None of these
    7). Answer: a)
    [(135)^2 ÷ 15 x 39] ÷ ? = 60 x 52
    or, [135 × (135/15) × 39] ÷ ? = 3120
    or, 47385 ÷ ? = 3120
    ? = 47385 / 3120 = 15.18


    8. 6348 + 8515 – 695 - ? = 4312 + 2162

    7394
    7943
    7439
    7440
    7694
    8). Answer: e)
    6348 + 8515 - 695 - ? = 4312 + 2162
    or, 14168 - ? = 6474
    or, ? = 14168 - 6474 = 7694

    9. 1272 ÷ ? = 1382 – 956 – 214

    6
    8
    16
    18
    21
    9). Answer: a)
    1272 / ? = 1382 - 1170
    or, 1272/? = 212
    ? = 1272 / 212 = 6

    10. 10^37 × 10^-33 = 10^?

    4
    7
    6
    5
    None of these
    10). Answer: a)
    10^? = 10^37 × 10^(-33)
    = 10^(37-33) = 10^4
    ? = 4

    Direction (11-20): What approximate value should come in place of question mark (?) in the following questions?
    11. 90.05 + 281 ÷ 4 – 151.06 = 3√?

    27
    343
    216
    729
    243
    11). Answer: d)
    3√? = 90.05 + 281 ÷ 4 - 151.06 90
    = 90 + 280 ÷4 - 151 = 90 + 70 - 151 = 9
    ? = 9 x 9 x 9 = 729

    12. 17.98^2 ÷ (4.05)^2 × 90.11 ÷ 4.98 = ?

    396
    336
    242
    325
    365
    12). Answer: e)
    ? = (18)^2 ÷ (4)^2 × 90 ÷ 5
    = (4.5)^2 × 18 = 20.25 x 18 = 364.5 = 365

    13. 80.04% of 150.16 + 60.02% of 50.07 = ?

    150
    125
    210
    175
    140
    13). Answer: a)
    ? = 80.04% of 150.16 + 60.02% of 50.07 = 80% of 150 + 60% of 50
    = 80 x 1.5 + 60 x 0.5 = 120 + 30 = 150

    14. √628 × 17.996 ÷ 15.04 = ?

    30
    10
    5
    20
    15
    14). Answer: a)
    ? = √628 x 17.996 ÷ 15.04
    = 625 × 18 ÷ 15 = 25 × 18 ÷15 = 30

    15. (1/8) × 121 + (1/5) × 76 - ? = 25

    5
    45
    15
    10
    25
    15). Answer: a)
    (1/8) x 121 + (1/5) x 76 - ? =25
    or, ? = (1/8) x 120 + (1/5) x 75 - 25 = 15 + 15 – 25 = 5

    16. (28.07 × 4.97 + 15 × 6.05) / [(7.03)2 + √256.10 + 13.0001] = ?

    2
    -2
    3
    6
    4

    16). Answer: c)
    ? = (28.07x4.97 + 15x6.05) /[ (7.03)2 + √256.10 +13.0001]
    ? = (28 x 5 + 15 x 6) / [(7)^2 + √256 + 13] =(140+90) / (49+16+13)
    = 230 / 78 = 2.94 = 3

    17. 849 of (11/16.13) of (441.26 / 20.98) ÷ (17.13 / 319.85) = ?

    238000
    201300
    234500
    231000
    213000
    17). Answer: d)
    ? = 849 × 11/16.13 × 441.26/20.98 ÷ 17.13/319.85
    = 850 × 11/16 × 441/21 × 320/17 = 50 × 11 × 21 × 20 = 231000

    18. √[√(14640) + √? ] = 13

    2400
    2916
    2305
    2210
    2350
    18). Answer: c)
    13 = √[√(14640) + √? ]
    Squaring both sides
    or, 169 = {√[√(14640) + √? ]} ^2 = √(14640) + √?
    or, 169 = √(14640) + √? = 121 + √?
    or, √? = 169 – 121 = 48
    ? = (48)^2 = 2304 = 2305


    19. 17.156 × (864.63 – 356.34) = ? – 6909.8003

    15782
    15802
    15402
    15852
    15560
    19). Answer: e)
    ? = 17 x (865 – 356) + 6910
    = 8653 + 6910 = 15563 = 15560

    2590
    2409
    2380
    2700
    2485
    20). Answer: d)
    ? = 5059 - 4567.8 + (221 x 9.7)
    = 5060 - 4570 + (221 x 10) = 5060 – 4570 + 2210 = 7270 - 4570 = 2700
