Q(1-5) In the following questions two equations numbered I & II are given. You have to solve both equations and mark the option.

  1. X² – 49√2X + 1200 = 0
    Y² – 45√3Y + 1518 = 0
    A. X > Y
    B. X <Y
    C. X ≥ Y
    D. X ≤ Y
    E. X = Y or relationship cannot be established
    B. X <Y
    Solution:
    X = 24√2, 25√2 = 33.94, 35.35
    Y = 23√3, 22√3 = 39.98, 38.10
    Representing on number line we get X<Y

  2. I. X²  + 15√2X + 112 = 0
    II. Y²  + 13√2Y + 84 = 0
    A. X > Y
    B. X <Y
    C. X ≥ Y
    D. X ≤ Y
    E. X = Y or relationship cannot be established
    D. X ≤ Y
    Solution:
    X = -14/√2, -16/√2
    Y = -12/√2, -14/√2 By comparison We get X ≤ Y

  3. I. 6X² – 75√2X + 450 = 0
    II.6Y² – 70√3Y + 588 =0
    A. X > Y
    B. X <Y
    C. X ≥ Y
    D. X ≤ Y
    E. X = Y or relationship cannot be established
    E. X = Y or relationship cannot be established
    Solution:
    X = 15/√2, 5√2 = 10.60, 7.07
    Y = 7√3, 14/√3 = 12.12, 8.08

  4. I. 12X² – 96X + 180 = 0
    II. 6Y² – 20Y + 6 =0
    A. X > Y
    B. X <Y
    C. X ≥ Y
    D. X ≤ Y
    E. X = Y or relationship cannot be established
    C. X ≥ Y
    Solution:
    X = 15/3, 12/4 = 5,3
    Y = 6/2, 1/3 = 3, 0.333

  5. I. X² = 289
    II.Y² – 34Y +289 =0
    A. X > Y
    B. X < Y
    C. X ≥ Y
    D. X ≤ Y
    E. X = Y or relationship cannot be established
    D. X ≤ Y
    Solution:
    X = 17, -17
    Y = 17, 17

Q(6-10) Find the missing number in the number series.

  1. 10, 22, 120, 1176, ?
    A. 16440
    B. 17240
    C. 19840
    D. 20040
    E. None
    C. 19840
    Solution:
    (10+1³)*2 = 22
    (22+2³)*4 = 120
    (120+3³)*8 = 1176
    (1176+4³)*16 = 19840

  2. 12, 13, 44, 423, ?
    A. 6523
    B. 6660
    C. 6960
    D. 6704
    E. None
    D. 6704
    Solution:
    12*1² + 1³ = 13
    13*2² – 2³ = 44
    44*3² + 3³ = 423
    423*4² – 4³ = 6704

  3. 1, 4, 9, 25, 69.5, ?
    A. 219.5
    B. 220.5
    C. 221
    D. 222.5
    E. None
    A. 219.5
    Solution:
    1*1+2+1 = 4
    4*1.5+4- 1 = 9
    9*2 +6 +1 = 25
    25*2.5 +8 -1 =69.5
    69.5*3 +10+1 = 219.5

  4. 365, 365, 372, 346, 409, ?
    A. 285
    B. 326
    C. 378
    D. 426
    E. None
    A. 285
    Solution:
    365 – 1³ + 1  = 365
    365 + 2³ – 1 = 372
    372 – 3³ + 1 = 346
    346 + 4³ – 1 = 409
    409 – 5³ + 1 = 285

  5. 2, 2, 3, 5.5, 12,?
    A. 29
    B. 30
    C. 31
    D. 31.5
    E. None
    C. 31
    Solution:
    2*0.5 +1 = 2
    2*1+1 = 3
    3*1.5 +1 = 5.5
    5.5*2 +1 = 12
    12*2.5 +1 = 31
