    Direction (1-10): What value should come in place of question mark (?) in the following questions?
    1). 24.5% of 48 + 8.4% of 125 = ?% of 139.125

    12
    14
    16
    18
    20

    1). Answer: c)
    ? × 139.125 / 100 = 24.5 × 48 / 100 + 8.4 × 125 / 100
    ? × 139.125 / 100 = 11.76 + 10.5
    ? = 22.26 × 100 / 139.125 = 16

    2. (24.84 ÷ ?) / (0.2 × 0.03) = 300

    11.2
    13.8
    14.5
    16
    18.8
    2). Answer: b)
    24.84 / ? = 300 × 0.2 × 0.03 = 1.8
    ? = 24.84 / 1.8 = 13.8

    3. 8/13 of 7/3 of 12.5% of 13728 = 320% of ?

    748
    756
    764
    770
    780
    3). Answer: d)
    320 × ? / 100 = 8 × 7 × 12.5 × 13728 / (13 × 3 × 100) = 2464
    ? = 2464 × 100 / 320 = 770


    4. (1296)^3.8 × (216)^(-4) ÷ 1 / 7776 = (36)^?

    3.2
    4.1
    4.8
    5.6
    2.8
    4). Answer: b)
    (6^4)^3.8 × (6^3)^(–4) ÷ 1 / (6)^5 = (36)^?
    (6)^15.2 × (6)^(-12) (6)^(–5) = (36)^?
    (36)^? = (6)^(15.2 - 12 + 5) = (6)^8.2 = (36)^4.1
    ? = 4.1


    5). √6084 ÷ ³√2197 = ³√?

    64
    125
    216
    343
    512
    5). Answer: c)
    ³√? = 78 ÷ 13 = 6
    ? = (6)^3 = 216


    6. (1089)^2.8 ÷ (33)^(-3.4) × 1/35937 = (1089)^?

    1
    2
    3
    4
    5
    6). Answer: c)
    (33^2)^2.8 ÷ (33)^(-3.4) × 1/ (33)^3 = 1089^?
    or, (33)^5.6 ÷ (33)^(-3.4) × (33)^(-3) = (1089)^?
    or, (33)^(5.6 + 3.4 – 3) = (1089)^?
    or, (33)^6 = (1089)^?
    or, (1089)^3 = 1089^?
    ? = 3


    7. 1.4641 ÷ 0.0011 = ?

    1
    11
    121
    1331
    14641
    7). Answer: d)
    ? = 1.4641 / 0.0011
    ? = 14641 / 11 = 1331


    8. 3.6% of 180 + 2.4% of 555 = ?% of 49.5

    40
    60
    80
    100
    120
    8). Answer: a)
    ? × 49.5 / 100 = 3.6 × 180 / 100 + 2.4 × 555 / 100
    ? × 49.5 / 100 = 6.48 + 13.32 = 19.8
    ? = 19.8 × 100 / 49.5 = 40

    9. 7/9 of 4/3 of 78% of 4950 = ?

    4004
    4008
    4012
    4016
    4020
    9). Answer: a)
    ? = 7 × 4 × 78 × 4950 /(9 × 3 × 100)
    ? = 4004

    1125
    1135
    1145
    1155
    1165
    10). Answer: b)
    ? = (7.25 × 244 – 2.75 × 148) / 1.2
    ? = (1769 – 407) / 1.2
    ? = 1362 / 1.2 = 1135

    Direction (26-30): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and given answer:
    a) If x< y
    b) If x ≥ y
    c) If x> y
    d) If x ≤ y
    e) Relationship between x and y cannot be established

    26. I. 9x^2 - 51x - 18 = 0
    II. 7y^2 – 61y – 18 = 0

    a)
    b)
    c)
    d)
    e)
    26). Answer: e)
    I. 9x^2 - 51x - 18 = 0
    x = – (54/9) , 3/9
    x = 6, -(1/3)
    II. 7y^2 – 61y – 18 = 0
    y = - (63/7), (2/7)
    y = 9, - (2/7)
    Hence relation can’t be established.

    27.I. 4x^2 - 3x - 27 = 0
    II. 6y^2 – 83y + 27 = 0

    a)
    b)
    c)
    d)
    e)
    27). Answer: e)
    I. 4x^2 - 3x - 27 = 0
    x = -(12/4), (9/4)
    x = 3, -(9/4)
    II. 6y^2 – 83y + 27 = 0
    y = (81/6) , (2/6)
    y = (27/2), (1/3)
    Hence no relation can be established.

    28. I. 21x - 4y = 140
    II. 9x – 8y = 148

    a)
    b)
    c)
    d)
    e)
    28). Answer: c)
    21x – 4y = 140 …(i)
    9x – 8y = 148 …(ii)
    Solving eqn (i) and (ii) we get
    [ 42x – 8y = 280 ] – [ 9x – 8y = 148]
    33x = 132
    x = 4
    Putting the value of x in equation (i), we get
    84 – 4y = 140
    Or, -4y = 56
    Y = -(56/4) = -14
    Hence x> y

    29. I. 3^(x-y) = 243
    II. 3^(x+y) = 27

    a)
    b)
    c)
    d)
    e)
    29). Answer: c)
    I. 3^(x-y) = 243
    3^(x-y) = 3^5
    x – y = 5 …(i)
    II. 3^(x+y) = 27
    3^(x+y) = 3^3
    x + y = 3 …(ii)
    By adding (i) and (ii), we get
    (x – y = 5) + (x + y = 3)
    2x = 8
    x = 8/2 = 4
    Putting the value of x in equation (i), we get
    4 – y = 5
    or, -y = 5 – 4 = 1
    or , y = -1
    Hence x> y

    30. I. 8x^2+ 27x+ 22 = 0
    II. 4y^2 – 25y -56 = 0

    a)
    b)
    c)
    d)
    e)
    30). Answer: e)
    I. 8x^2+ 27x+ 22 = 0
    x = (16/8), (11/8)
    x = -2, -(11/8)
    II. 4y^2 – 25y -56 = 0
    y = - (32/4), (7/4)
    y = 8, -(7/4)
    Hence no relation can be established.
