Directions(1-5): Find the relation between x and y and choose a correct option.

  1. I. 8x2 + 6x + 1 = 0
    II. 5y2 + 8y – 4 = 0

    y>=x
    x>y
    x>=y
    y>x
    x=y or no relation cannot be established.
    Option E
    I. 8x2 + 6x + 1 = 0
    8x2 + 6x + 1 = 0
    8x2 + 4x + 2x + 1 = 0
    x = -1/4, -1/2
    II. 5y2 + 8y – 4 = 0
    5y2 + 8y – 4 = 0
    5y2 + 10y – 2y – 4 = 0
    y = -2, 2/5
    x = y or relationship cannot be determined

     

  2. I. 12x2 – 5x – 3 = 0
    II. 4y2 – 11y + 6 = 0

    y>=x
    y>x
    x>=y
    x=y or no relation cannot be established.
    x>y
    Option A
    I. 12x2 – 5x – 3 = 0
    12x2 – 5x – 3 = 0
    12x2 + 4x – 9x – 3 = 0
    x = -1/3, 3/4
    II. 4y2 – 11y + 6 = 0
    4y2 – 8y – 3y + 6 = 0
    y= 3/4, 2
    x ≤ y

     

  3. I. 2x2 – (6 + √3)x + 3√3 = 0
    II. 3y2 – (9 + √3)y + 3√3 = 0

    x=y or no relation cannot be established.
    y>x
    x>y
    y>=x
    x>=y
    Option A
    I. 2x2 – (6 + √3)x + 3√3 = 0
    2x2 – 6x – √3x + 3√3 = 0
    2x (x- 3) – √3 (x – 3) = 0
    x = 3, √3/2 (0.7)
    II. 3y2 – (9 + √3)y + 3√3 = 0
    3y2 – 9y – √3y + 3√3 = 0
    3y (y – 3) – √3 (y – 3) = 0
    y = 3, √3/3 (0.6)
    x = y or relationship cannot be determined

     

  4. I. 9/√x + 8/(√x +1) = 5
    II. 12/√y – 4/√y = 2

    x>=y
    y>=x
    x>y
    x=y or no relation cannot be established.
    y>x
    Option E
    I. 9/√x + 8/(√x +1) = 5
    9/√x + 8/(√x +1) = 5
    [9(√x +1) + 8√x]/[√x * (√x +1)] = 5
    17√x + 9 = 5 (x + √x)
    5x – 12√x – 9 = 0
    5x – 15√x + 3√x – 9 = 0
    5√x (√x – 3) + 3 (√x – 3) = 0
    √x cannot be -3/3
    So √x = 3
    x = 9
    II. 12/√y – 4/√y = 2
    12/√y – 4/√y = 2
    8/√y = 2
    √y = 4
    y = 16
    y > x

     

  5. I. 4x2 – 23x + 30 = 0
    II. 4y2 – 3y – 45 = 0

    y>=x
    x>y
    x>=y
    y>x
    x=y or no relation cannot be established.
    Option E
    I. 4x2 – 23x + 30 = 0
    4x2 – 23x + 30 = 0
    x2 – 15x – 8x + 30 = 0
    x = 15/4, 2
    II. 4y2 – 3y – 45 = 0
    4y2 – 3y – 45 = 0
    4y2 + 12y – 15y – 45 = 0
    y = -3, 15/4
    x = y or relation cannot be established

     

  6. Directions(6-10): Study the following pie-chart and answer the following questions.
    Total number of Employees = 12600 Percentage-wise distribution of Employees

  7. What is the average number of employees in Accounts, Admission and Research department together?
    1620
    1700
    1525
    1722
    1202
    Option D
    Number of employees in Accounts Department
    =17 * 12600/100 = 1890
    Average = 2142 + 1134 + 1890/3
    = 5166/3 = 1722

     

  8. What is the difference between the total number of employees in the department of HR and Admission together and the total number of employees in Accounts and Examination department together?
    2268
    2200
    2040
    2525
    3500
    Option A
    Difference = (38% of 12600 – 20% of 12600)
    = 18% of 12600
    = 18 * 12600/100
    = 2268

     

  9. The number of employees in Examination department is approximately what percentage of the total number of employees in the department of HR and Academic Affairs together?
    40
    55
    30
    60
    80
    Option B
    Number of employees in examination department
    = 21 * 12600/100 = 2646
    Number of employees in the HR Department = 11 * 12600/100 =1386
    Number of employees in Academic Affairs 27 * 12600/100 = 3402
    Total number of employees in both the departments Academic Affairs and HR together = 3402 + 1386 = 4788
    Required % = 2646/4748*100 = 55.26 == 55

     

  10. If 30 per cent of the number of employees of Research department is females, then what is the number of male employees in the Research department?
    1470
    1350
    1454
    1600
    1323
    Option E
    Number of employees in Research Department = 15 * 12600/100 =1890
    female employees in Research department = 1890 * 30/100 = 567
    Hence, number of male employees in Research department = 1890 – 567
    = 1323

     

  11. The number of employees in the department of Academic Affairs is approximately what per cent more than the number of employees in Examination department?
    18%
    10%
    29%
    31%
    14%
    Option C
    Number of employees in Academic affairs
    = 27 * 12600/100 = 3402
    Number of employees in Examination Department = 21 * 12600/100 = 2646
    Required % = (3402 – 2646)/2646*100 = 28.57 == 29%
