Practice the questions so as to familiarize yourself with the pattern of questions to be asked in the exam. 

 

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

  1. I. (17)^2 + 144 /18 = x
    II. (26)^2 – 18*21 = y

    x>=y
    x>y
    y>=x
    y>x
    x=y or relation cannot be established.
    Option D
    I. (17)2 + 144 /18 = x
    => x = 297
    II. (26)2 – 18*21 = y
    =>y = 298
    y>x

     

  2. I. 16x2 -106x +13=0
    II. 8y2 + 47y – 6 = 0

    y>x
    y>=x
    x=y or relation cannot be established.
    x>y
    x>=y
    Option E
    I. 16x2 -106x +13=0
    16x2 – 104x – 2x + 13 =0
    => (2x – 13)(8x – 1)=0
    => x= 13/2 , 1/8
    II. 8y2 + 47y – 6 = 0
    8y2 + 48y -1y – 6 =0
    => (y+6)(8y – 1) = 0
    => y = -6, 1/8
    x>=y

     

  3. I. x2 – 529 = 0
    II. y3-19683 = 0

    x>y
    x=y or relation cannot be established.
    x>=y
    y>=x
    y>x
    Option E
    I. x2 – 529 = 0
    => x = +23, -23
    II. y3 -19683 = 0
    => y = 27
    y>x

     

  4. I. 40x2 -101x +12 =0
    II. 40y2 – 13y + 1 =0

    x>=y
    y>=x
    y>x
    x>y
    x=y or relation cannot be established.
    Option A
    I. 40x2 -101x +12 =0
    40x2 – 96x – 5x + 12 =0
    => (5x – 12)(8x – 1) = 0
    => x = 12/5, 1/8
    II. 40y2 – 13y + 1 =0
    40y2 – 8y – 5y + 1 =0
    => (8y – 1)(5y – 1) = 0
    => y = 1/8, 1/5
    x>=y

     

  5. I. 55x2 – 495x + 1100 =0
    II. 5y2 + 10y – 120 = 0

    y>=x
    y>x
    x>=y
    x=y or relation cannot be established.
    x>y
    Option C
    I. 55x2 – 495x + 1100 =0
    55x2 – 220x – 275x + 1100 =0
    => x = 4,5
    II. 5y2 + 10y – 120 = 0
    5y2 + 30y – 20y – 120 =0
    => y = -6,4
    x>=y

     

    6. Directions(6-10): Study the following table carefully and answer the questions that follow.
    Few values are missing in the table. A candidate is expected to calculate the missing value, if it is required to answer the given questions on the basis of the given information.

  6. The number of appeared candidates from State B increased by 100% from 2010 to 2011. If the total number of qualified candidates from State B in 2010 and 2011 together is 408, what is the number of appeared candidates from State B in 2010?
    300
    280
    340
    330
    310
    Option C
    Let the number of appeared candidates form State B in 2010 be x.
    Then number of appeared candidates in 2012 = x + (x*100)/100 = 2x
    Now, (x*30)/100 + (2x*45)/100 = 408
    =>12x = 408*10
    => x= 340

     

  7. If the ratio of the number of qualified candidates from State A in 2013 to that in 2014 is 14:9, what is the number of qualified candidates from State A in 2014?
    150
    200
    188
    216
    110
    Option D
    In 2013, number of qualified candidates
    = (480*70)/100 = 336
    Let the number of qualified candidates from State A in 2013 be 14x and that in 2014 be 9x.
    Then,
    14x = 336
    => x = 24
    So, the number of qualified candidates from State A in 2014
    = 9*24 = 216

     

  8. What is the difference between the number of qualified candidates from State A in 2010 and that in 2011?
    12
    10
    8
    15
    20
    Option A
    Required difference
    = (450*60)/100 – (600*43)/100
    =270-258 = 12

     

  9. If the average number of qualified candidates from State B in 2012, 2013 and 2014 is 210, what is the number of qualified candidates from State B in 2014?
    125
    187
    170
    154
    136
    Option B
    Let the percentage of candidates who qualify from State B in 2014 be x%.
    Average
    => [(280*60)/100 + (550*50)/100 + 400*x%]/3= 210
    => x = 46.75%
    Number of qualified candidates from State B in 2014 = (400*46.75)/100
    = 187

     

  10. Out of the number of qualified candidates from State A in 2012, the ratio of male to female candidates is 11:7. If the number of female qualified candidates from State A in 2012 is 126, what is the number of appeared candidates (both male and female) from State A in 2012?
    400
    480
    380
    520
    540
    Option E
    Let the number of male and female qualified candidates be 11x and 7x respectively.
    Then, 7x = 126
    => x = 18
    Males = 18*11 = 198
    Total number of qualified candidates = 198+126 = 324
    Let the number of appeared candidates be y.
    Then , y * 60% = 324
    => y = (324*100)/60 = 540
