    Direction (1-10): What value should come in place of question mark (?) in the following questions?
    1). 1/6 of (92)% of 1 1/23 of (650) = 85 + ?

    18
    21
    19
    28
    None of these

    1). Answer: c)
    650 × 24/23 × 92/100 × 1/6 = 85 + ?
    or, ? = 104 - 85 = 19

    2. 92 × 576 ÷ (2 × √1296) = (?)^3 + √49

    3
    9^2
    9
    27
    None of these
    2). Answer: c)
    92 × 576 ÷ (2 × √1296) = (?)^3 + √49
    or, 92 × 576 / 72 = (?)^3 + 7
    or, 736 - 7 = ?^3
    ?3 = 729
    ? = ³√729 = 9

    3. 3 1/4 + 2 1/2 – 1 5/6 = (?)^2 /10 + 1 5/12

    25
    √5
    625
    15
    5
    3). Answer: e)
    (3 + 2 – 1 – 1) + (1/4 + 1/2 – 5/6 – 5/12) = ?^2 / 10
    3 + ((3 + 6 – 10 – 5) / 12) = ?^2 / 10
    3 - 6/12 = ?^2 / 10
    3 – 1 /2 = ?^2 / 10
    ?2 = 5/2 × 10 = 25
    ? = 5.


    4. (√8 × √8)^(1/2) + (9)^(1/2) = (?)^3 + √8 – 340

    7
    19
    18
    9
    None of these
    4). Answer: a)
    (√8 × √8)^(1/2) + (9)^(1/2) = (?)^3 + √8 – 340
    √8 + 3 = (?)^3 + √8 – 340
    (?)^3 = 340 + 3
    (?)^3 = 343
    ? = 7


    5. (15 × 0.40)^4 ÷ (1080 ÷ 30)^4 × (27 × 8)^4 = (3 × 2)^(?+5)

    8
    3
    12
    16
    None of these
    5). Answer: b)
    (15 × 0.40)^4 ÷ (1080 ÷ 30)^4 × (27 × 8)^4 = (3 × 2)^(? + 5)
    6^4 ÷ (36)^ 4 × (216)^ 4 = (6)^(? + 5)
    6^4 ÷ (6^2)^4 × (6^3)^ 4 = (6)^ (? + 5)
    6^(4 + 12 – 8) = (6)^(? + 5)
    (6)^ 8 = (6)^(? + 5)
    ? + 5 = 8
    ? = 3

    15
    18
    21
    24
    7). Answer: b)
    ? × 999 / 100 = 166.5 × 0.9
    ? = 14985 / 999 = 15


    8. {(157.8)^2 - (117.2)^2} × 0.008 = ?

    89.32
    92.34
    94.86
    96.12
    98.5
    8). Answer: a)
    ? = {(157.8 + 117.2) × (157.8 - 117.2)} × 0.008
    ? = (275 × 40.6) × 0.008 = 11165 × 0.008

    1130
    1230
    14). Answer: d)
    5998 ÷ 9.98 + 670.99 - 139.99 = ?
    ? ≈ 6000/10 + 670 – 140
    ? = 600 + 670 – 140
    ? = 1130
